2 Product Description
2.1 General
The EE300Ex-M1 and the EE300Ex-M3 intrinsically safe sensors are intended for the measurement of
relative humidity (RH) and temperature (T) or temperature alone, in the explosion hazard areas, in gas
and dust up to Zone 0/20. The entire device can be placed in the explosion endangered area.
The sensor may only be powered by an intrinsically safe power supply device or protective barriers.
It features a 2 wire 4…20 mA design and has two individually scalable analogue outputs.
In addition to the measured RH and T, the EE300Ex-M1 calculates also the following parameters:
• Absolute humidity dv
• Wet-bulb temperature Tw
• Specific enthalpy h
• Dew point temperature Td
• Frost point temperature Tf
• Mixing ratio r
• Water vapour partial pressure e
Besides measurement in the air, the EE300Ex-M1 with ATEX or IECEx approval is also suitable for
measuring water content (X) in ppm and water activity (aw) in isolation, lubrication and
hydraulic oils.
EE300Ex-M1 humidity and temperature sensor types:
Type Pressure range Temperature range Probe Ø)
T1 Wall mount ambient -40...60 °C (-40...140 °F) 12 mm (0.47")

3.1 General
The EE300Ex is certified according to ATEX 2014/34/EU Directive, IECEX Scheme, National Electrical
Code ANSI-NFPA 70 (NEC©) and Canadian Electrical Code (CSA C22.1).
The use of the EE300EX in explosion hazard areas is only permitted under following atmospheric conditions:
 -20°C(-4°F) ≤T≤ 40°C(104°F)
 0.8bar(12psi)≤p≤ 1.1bar(16psi)

The EE300Ex may be employed beyond above atmospheric conditions range only observing EN 1127-1
and only in line with the manufacturer‘s instructions.
The EE300Ex may only be supplied by intrinsically safe power supply devices or via protective barriers.
This applies also for the case when just the probe is located inside the explosion hazard area.
The rules for wiring intrinsically safe electrical circuits according to EN 60079-14, EN 60079-25, IEC
60079-14, IEC 60079-25 (proof of intrinsic safety in the system description) as well as all applicable
national regulations must be strictly observed. For the U.S., Canada refer to the Control
Drawing M1_1309080 (page 51) and ANSI/ISA RP12.6.01, NEC and CEC.
The intrinsically safe circuitry shall include an overvoltage protection device if the analysis according EN
1127-1 reveals a risk of lightning strike.
Requirements for the installation of overvoltage protection devices are set in European Normative EN
60079-25. For the U.S., Canada refer to ANSI/ISA RP12.6.01, NEC and CEC.

3.5 Probe Mounting
The probe of the EE300EX sensor shall be located
at the most representative location for the RH and
T of the process to be monitored.
For accurate measurement it is of paramount
importance to avoid temperature gradients along
the probe.
Whenever possible, install the entire probe inside
the environment to monitor. If the probe is installed
into a wall, than isolate thermally the backend of
the probe looking out of the wall.
The probe shall be mounted horizontally or vertically, with the tip of the probe pointing downwards.
In applications where condensation is likely to happen:
• The cable shall form a drip
loop close to the probe.
• Use the drip water protection
(see datasheet accessories,
code HA010503) for vertically
mounted probe.

User Manual EE300Ex Humidity / Temperature Sensor
Ensure appropriate mechanical stability and sealing of the probe mounting taking into account specific
influences at the site, such as vibrations, shocks or temperature changes.
The probe and the cabling shall be handled and installed to avoid electrostatic charges. (e.g. metal
hose)
Filter caps
The following filter caps offer good protection against electrostatic discharge for explosion group IIB, but
are not permitted for use in EPL Ga IIC or Class I, Division 1, Group A, B:
• Membrane filter (order code F2)
• PTFE filter(order code F5)
• Membrane on stainless steel body (order code F10)
• PTFE on stainless steel body (order code F11)
• H2O2filter (order code F12)
The following filter caps are permitted for use in EPL Ga IIC or Class I, Division 1, Group A, B:
• Stainless steel sintered (order code F4)
• Stainless steel grid (order code F9)
• Oil (order code F13)
Filter caps F2, F5, F10, F11 and F12 not allowed for EX6 (TIIS)
3.5.1 Probe Feedthrough with Cut-in Fitting
The feedthrough with cut-in fitting (ordering code PA20, PA21, PA22) can be used as Zone or Division
bushing. For this, the tightness of its mounting into the Zone separation wall must correspond to IP67.
Once mounted, the cut-in fitting creates a permanent clamping-ring onto the probe.
Safety instructions for pressure-tight feedthrough:
• Do not assemble the probe and tighten the feedthrough if the plant is under pressure.
• The plant must not be vented by releasing the nut (A).
• Use appropriate seal on conical probe threads.
• Never rotate the screw connection body (B) but hold the screw connection body (B) securely and turn
the nut (A).
• Avoid unnecessary disassembly of pipe screw connections.
• Position the cut in fitting >75 mm (2.95”) from the end of the filter cap to the end of the fitting!
For a probe length of 65 mm a cut in fitting is not possible.
>75 mm (2.95“)
Installation instructions:
• Tighten the nut (A) finger-tight.
• Mark the nut (A) at 6 o‘ clock position.
• Hold the screw connection body (B) tight and tighten the nut (A) with
1 ¼ turns till 9 ‚o clock position.
Assembly with high pressure applications and applications with a
high security factor:
• Tighten the nut (A) until the probe (C) can no longer be turned by
hand and moved axially in the feedthrough.
• Mark the nut (A) at 6 o‘ clock position.
• Hold the screw connection body (B) tight and tighten the nut (A) with
1 ¼ turns to 9‚ o clock position.

Re-mounting:
• Slide the measurement probe with clamping ring into the fitting as far as it goes.
• Tighten the nut finger-tight, then tighten by approx. a ¼ turn using a spanner.
3.5.2 Mounting Flange
The optional mounting flange (see datasheet accessories) may not be used as Zone or Division
bushing. When installed with the mounting flange, the hazard areas on the filter cap side and at the
cable outlet side must be of the same category.
3.5.3 Ball Valve and Sliding Fitting
The optional ball valve HA011403 (ATEX certified)
allows for the probe to be mounted or removed without
interrupting the process to be monitored.
Only ball valve approved for use in explosion hazard
areas are permitted.
The two metal sealing rings (see figure) shall be
replaced with new ones after each removal of the
probe.
MOUNTING THE PROBE:
The process temperature may not deviate from the
mounting temperature by more than ±40 °C (104 °F).
The maximum permitted process pressure during
mounting is 10 bar (145 psi).
• Mount the probe onto the ball valve with the ball
valve closed.
• Open the ball valve.
• Slide the probe through the ball valve into the pro-
cess to the desired immersion depth. For rather high process pressure a manual pressing tool might
be needed for sliding easily the probe into the process.
• For secure probe installation the closing nut shall be tightened with a torque of 30 Nm. If a torque
wrench is not available, turn first the closing nut by hand as tight as possible, then turn another
approx. 50° using a suitable open-ended spanner.
A lower tightening torque means lower clamping force of the clamp sleeve. Consequently there is a
risk for the probe being pushed out by the process pressure.
An excessive tightening torque may cause permanent deformation of the clamping sleeve and of the
probe. This makes the removal and re-mounting difficult or even impossible.
