<1. Introduction>
1. Introduction
The EJA564E solid-state pressure and level
transmitters are based on a piezoresistive silicon
sensor, with a very high burst pressure. The
sensor element is mounted in a stainless steel
"foot".Atemperature sensor is mounted inside the
foot to and is used for active temperature
compensation. A strong stainless steel “flush”
diaphragm protects the sensor from the process
medium. A minimal amount of special oil fills the
chamber surrounding the sensor and transfers
pressure from the flush mounted diaphragm to the
sensor hydraulically.
Pressure on the sensor element creates a small
deection of the silicon substrate and bridge network.
The resulting strain in the silicon resistors causes a
change in the bridge resistance that is proportional to
the pressure being applied. The transmitter
electronics detect this change in the bridge
resistance and converts it into the measured value.
The amplifier system is based on a single Integrated
Circuit, which ensures perfect linearity in the output,
all within an accuracy of 0.2 %.
1.1 Description
The EJA564E transmitter is specially designed with
a flush mounted diaphragm so it fully meet the
needs of the food, pharmaceutical, chemical and
other industries. Standard wetted parts are made of
316L SST, other materials are also available, like
Hastelloy C. Various process connections can be
adapted and available for manufacture;
(1.5”, 2” and 3” tri-clamp), SMS (1.5” and 2”), dairy
milk couplings (DN 25, 40 and 50), flanges (DIN and
ANSI) and sanitary weld-on nipples (ø 48, 62 and
85 mm.), among others.
Certain variants of the EJA564E are designed to be
non-clogging and are capable of being cleaned
inside. Various process connection types are
manufactured according to 3-A (74-06)
requirements such as Tri-Clamp and others.
1.2 Barometric Reference
The EJA564E is a “relative transmitter” which means
that barometric changes will not affect the zero.
The venting is placed in the cover of the electronics
housing next to the cable entry and is the lter for the
barometric reference to atmospheric pressure.
The vent mechanism must be kept clean.

<3. Installing the Transmitter>
3. Installing the Transmitter
The diaphragm of the transmitter is protected with
a special protection cap. Protect the diaphragm
until installation takes place. Take special care
with the fragile diaphragm.
3.1 Installing Weld-On Nipple
A certied welder should perform the installation of
the weld-on nipple. Weld with Argon, MIG or TIG,
with the smallest welding pin possible.
1. Cut a hole in the process vessel or pipe for
a precise t of the weld-on nipple. The hole
should be a tight t when coupled with the
weld-on nipple.
2. Prepare the hole by bevelling the edge to
accept ller material.
3. Remove the weld-on nipple from the
transmitter.
Remove the gasket and O-Ring out of the
weld-on nipple!
WARNING
Improper installation may result in distortion
of the weld-on nipple. Excessive heat will
distort the weld-on nipple. Weld in sections
as shown in the figure below and allow
adequate cooling between passes. To
reduce the chances of distortion to the weld-
on nipple, use a mandrel.
4. Position the weld-on nipple in the vessel hole
and tack six places. The weld sequence is
shown in the gure above.
5. Weld the weld-on nipple in place using 0.03
to 0.045 in. (0.762 to 1.143 mm) stainless rod
as ller material in the bevelled area. Adjust
amperage for penetration.
6. Remove the mandrel after the welding
operation.
3.2 Installing Transmitter
(Code W33)
1. After welding, clean up edges, and take care
of the inside nipple wall.
2. Make sure the O-ring (10) is properly located.
3. Improper installation of the O-ring can cause a
process leak.
4. Apply silicone grease to the O-ring (10),
diaphragm ring and the hole inside wall of
the weld-on nipple, this prevents galvanic cell
corrosion between transmitter and the nipple
inside.
5. Install the transmitter and x it with the SS M8
bolt.
3.3 Mounting Position
When the transmitter is mounted horizontally,
the cable gland must be pointed downwards.
Furthermore, 3-A certified units with leakage
detection holes in weld-on nipples should be on
the lowest point and pointing down 90 degrees
from the horizontal.
3.4 Mounting Position Effect
All transmitters are calibrated in a vertical position
(diaphragm points downwards). If the transmitter is
mounted in another position, there can be a slight
zero shift. (example 4.02 mA instead of 4.00 mA).
After installation of the transmitter,the zero must
be set to 4.00 mA with P103 (cancelsmounting
position effect). This will not affect the span.
3.5 Calibration
All transmitters are calibrated at the factory to the
customer specified range. If the calibration is not
specified, the transmitter will be calibrated to the
maximum span.
Determine (before welding) the position of
the electronics housing so that the cable
entry and the venting are in the right position.
These positions are fixed after welding.

<3. Installing the Transmitter>
3.6 Connection Terminal
The figure below shows the wiring connection of the transmitter. The 2-wires must be connected to the
terminal board. The wiring terminals can be connected without a screwdriver. The opening levers of the
terminal can be lifted and pressed down by hand. Lift the opening levers of the terminals and insert the
corresponding wires. Press down the levers by hand. The terminal spring will close and the wire is clamped.
3.7 Wiring
The transmitter must always be connected to ground. The transmitter must be connected with standard
two-wire shielded cable. Do not run signal wiring in open trays with power wiring or near heavy electrical
equipment (Frequency controller or heavy pumps). Shielding must always be connected at the side of the power
supply. In case the process connection is already connected to ground (e.g. via the tank or pipe line) do not
connect the instrument to ground. Please ensure that the instrument is not connected to ground twice to prevent
an ‘earth loop’. In applications with synthetic process connections, the enclosure (internal or external) must be
connected to ground.
Reversing the polarity will not damage the transmitter, but the transmitter will not function until the + and – are
properly connected.
CAUTION
•Please ensure that the transmitter is not connected to ground twice to prevent an earth loop.

6.2 Span Adjustment
(SPAN)
This setting can be used to adjust
the range (SPAN) according to an
entered value or adjusted with or without an applied
pressure. The maximum pressure value that can be
measured: The measurement at ZERO (P101) +
the entered value SPAN (P102). If the ZERO (P101)
is increased, the maximum measured value will
automatically be set higher by the same amount as
the zero. This will be explained step by step by an
example.
6. Explanation of Programming Points
6.1 Zero Adjustment
(ZERO)
The transmitter is set to 0 mbar at
atmospheric pressure.
The ZERO can be adjusted at a lower or higher
point. This will be explained step by step by an
example.
Example: Increase ZERO to 100 mBar.
1. The measuring unit of the transmitter is set to
mBar. If not, this can be selected by choosing
the right measuring unit in program point
P104.
2. Navigate to program point P101, and push the
menu button to enter the menu.
3. The actual measured value appears on the
display.
4. Increase this value with the arrow button to
100 mBar, and push the button until
save appearson the display.
5. The transmitter will return to the home screen.
The measurement value at atmospheric
pressure is now -100 mBar. At an applied
pressure of 100 mbar the transmitter will
display 0 mbar.
The transmitter can be adjusted to zero in a real
process situation. The transmitter will measure the
pressure in an actual process. This measurement
will be used as the zero value (4 mA).
1. Go to the home screen, the transmitter will
display the actual measured value.
2. Push the button until the actual measured
zero andthe message ZERO PUSHED
appearson the display.
3. The transmitter will return to home screen.
Example: Measurement range 0 – 2000 mbar.
1. The span must be set to 2000 mbar
2. Navigate to program point P102, and push the
menu button to enter the menu.
3. Adjust the SPAN with the push buttons to
2000 mbar and push the button until save
appearson the display.
4. The transmitter will return to the home screen.
The span can also be adjusted to a real process
situation. The transmitter will measure the pressure
in an actual process. This measurement will be used
as the span value (20 mA).
1. Go to the home screen, the transmitter will
display the actual measured value.
2. Push the button until the actual measured
span and the message SPAN
PUSHED appearson the display.
3. The transmitter will return to home screen.
TIP
P102 is the adjustment of the total span.
When a compound range must be adjusted
(for example -1 till +3 bar), a span of 4 bar
must be programmed.
The Zero (P101) must be set at -1 bar. The
transmitter is adjusted at - 1 bar = Zero and +3
bar = Span.
6.3 Cancel Mounting
Position Effect
All transmitters are calibrated
vertically. If the transmitter is
installed horizontally, the transmitter has a small

9. Precautions and Warnings
CAUTION
• Check if the specications of the transmitter meet the needs of the process conditions
•When the EJA564E is used as a level transmitter, be aware of the place where the transmitter is
mounted. Here are some suggestions:
•DO NOT mount a level transmitter in- or near lling or discharging pipes.
• In case of automatic cleaning systems or hand cleaning: never point the water jets on the
diaphragm, take necessary steps to avoid this. This will void the warranty.
•When the EJA564E is used as a pressure transmitter, be aware of the following points:
•Rapid closing valves in combination with high ow velocity will cause water hammer(spikes) and
can destroy the transmitter. DO NOT mount a transmitter near such valves, always a few pipe
bends away up or down stream (avoid suction).
•Install a pressure transmitter a few pipe bends away from pumps, as well on the suction or
pressure side of the pump.
nWelding Information
CAUTION
•When using the EJA564E process connectors suffix code “W□□”, the welding information on
page 6 must be followed exactly. This is very important to prevent distortion of the weld-on
nipples. It also prevents the screw thread from the EJA564E from being deformed.
•The diaphragm of the transmitter is protected with a special protection cap. Protect the diaphragm until
installation takes place to prevent damaging of the diaphragm.
• Configuring the transmitter locally and remotely simultaneously will cause transmission errors and must be
prevented.
•As soon as the wiring is brought inside through the cable gland and connected to the terminal board,
make sure the cable gland is tightly fixed so that moisture cannot enter into the electronics housing.
• Avoid high pressure water-jets pointed at the venting.
•If the ambient conditions are very wet, we advise to use a venting through the cable. A special vented
cable can be connected on request. (The normal venting will be removed) In that case the transmitter is
IP68 rated.
•The covers must be fully engaged so that moisture cannot ingress into the electronics housing.
