OPP-SENS® Pressure transmitter for water P-…
• Captive cover with 8-way positioning
• IP65 housing including seal
• Fast cable connection due to rotary lid and
spring terminals – tool-free
• 10 oset points: linear shift of characteristic
curve using the rotary switch
• 10 measurement ranges can be set using
the rotary switch
• 5P calibration: interpolation of the output
characteristics curve with 5 user-dened
interpolation points
Optional:
• Illuminated display, indicator and control
panel with capacitive keys
• BACnet / Modbus versions with 2 cable glands
Function
Measuring the pressure of uids in pipes and containers.
Installation
All work (such as assembly, electrical connection, commissio-
ning, operation and maintenance) must be carried out by sui-
tably qualied personnel. The current local rules and regulations
(e.g. building regulations, electrical/VDE guidelines etc.) should
be observed. Installers and operators are required to inform
themselves suciently before use. Read the product description
before operating. Make sure that the product is suitable for your
application. We accept no liability for misprints or changes after
publication. Intended use also includes compliance with the
operating and installation instructions. We assume no liability
for damage caused by improper use. Unauthorized or improper
alterations to this device will invalidate the type approval and
the warranty and guarantee claims.
Because of its minimal dimensions, the pressure transmitter
can be screwed almost anywhere via a sleeve into the medium,
if possible via a pressure gauge value with shut-o ventilation.
Attention to proper sealing should be ensured.

Important recommendations for installation
• The ceramic diaphragm can be ruptured by pressure con-
ditions or mechanical contact. HANDLE WITH CARE. Do not
attempt to test the sensor by pressing on the diaphragm.
• Short pressure pulses or surges (also called“hydro lock”)
are generated by a rapid change in the ow rate caused by
the operation of system components such as compressors,
pumps, pistons and valves. Hydro lock can reach pressure
levels that exceed the pressure rating of our pressure sensors
and damage the ceramic membrane.
• A pressure reducer (“snubber”) is a device to reduce the rate
of change of the ow system. The installation of a properly
sized snubber at the input of a pressure sensor, or nearby,
protects it from hydro lock damages. Snubbers are available
through plumbing and instrumentation dealers.
• When the sensor is screwed into a pipe system, back pressure
can cause damage to the ceramic membrane. Open nearby
valves to relieve any back pressure when screwing the sensor
into the pipe.
• While threading the sensor, if the nearby valves cannot be
opened in the pipe, a vent valve can be installed to prevent
over pressure.
• Make sure that there are no air bubbles in the pipe, especially
if a long tube is used to connect to the process pipe. Air
bubbles can cause measurement variations and errors. Main
valve closed.

5P calibration
In all of the pressure transmitters 5-point calibration can be per-
formed. (optional display required).
Between the two end values 5 points can be adjusted as required
in X (sensor reading) and Y (output value). There is a linear inter-
polation between these points.
A reference point cannot be made through the measurement
limits in X and Y. The X values of the nodes must be numerically
in the order 1-2-3-4-5.
Non-monotonic values are ignored.
The following gures illustrate this:
Since the curve shown in the lower gure between the nodes
3 and 4 would be ambiguous (dashed line), the support
point 4 is ignored.
Should less than 5 calibration points be used, the unused
set points for X values should be set at the lower limit
(minimum setting) or the upper end value (maximum setting).
The corresponding Y value can be arbitrary.
In the conguration menu under
“ passwd ” , enter the string
“ 0000 ”* (by pressing the button to jump to the next position,
with the
and keys to change the respective number), the
calibration menu opens. Then additionally can be selected:
