Product description
Humidity and temperature transmitter E2218 is a member of the new PluraSens® family of
multifunctional measurement instruments. The transmitter is intended for measurement of
relative humidity and temperature in air and non-aggressive gases with high accuracy and
stability. Absolute humidity and dew point values can be found as well.
The instrument utilises digital fully calibrated and temperature compensated combined
relative humidity and temperature sensors with excellent repeatability and stability. Thanks
to the digital interface the sensor probes are detachable and fully interchangeable. The
range of probes for different applications may be attached to the main unit using standard
water- and dustproof M12 connectors.
Two freely configurable 4-20 mA or 0-10 V analog outputs can be used to connect the
transmitter to secondary instruments. Each output can be independently assigned either to
temperature, relative humidity or dew point channel. RS485 interface with
industry-standard Modbus RTU protocol allows direct Fieldbus networking of the
transmitter.
Safety requirements
Always adhere to the safety provisions applicable in the country of use.
Do not perform any maintenance operation with the power on. Do not let water or foreign
objects inside the device.
Operating conditions
The device should be used in explosion-safe (non ATEX -rated) indoor areas, without
aggressive gases in the atmosphere. Allowed conditions are:
– Temperature in the range of -40...+85 °C;
– Relative humidity in the range of 0...100%;
– Atmospheric pressure in the range of 84...106,7 kPa.

Installation and connections
Connect the sensor probe to the device main unit directly or via connecting cable.
Mark and drill four mounting holes on the wall at the chosen mounting place (see
dimensional drawing).
Unscrew four lid screws and detach the lid from the instrument. Fix the transmitter through
mounting holes by screws.
Plug the power cable and connect the analog outputs and/or digital interface terminals to
the relevant devices according to the connection diagram and table.

Make certain that the cable gland is properly tightened to ensure the conformity to IP65
protection class.
The screwless quick connect spring terminals on the E2218 are suitable for a wide range
of wires with cross-section 0,2...1,5 mm2. The recommended wire stripping length is 8...9
mm. Push the spring loaded terminal lever, insert the wire end into the terminal hole and
release the lever.
Use twisted pair cable, e.g. LiYY TP 2×2×0,5 mm2 or CAT 5, to connect the device to the
RS485 network. Use one pair for A and B wires and the second pair for common 0V and
power +U wires. to connect the transmitter to the Fieldbus network.polarity must be
respected when connecting to an external RS485 network.
Overall length of all connections via RS485 interface should not exceed 1200 m.
Place the lid back and tighten it with the four screws.
Both analog outputs can be independently changed between 4-20 mA and 0-10 V type
using jumpers J1 (OUT1) and J2 (OUT2). By closing pins on a specific jumper the related
output is 0-10 V, with an open jumper the output is 4-20 mA. Power restart is required after
changing the position of the jumpers.
By default the output OUT1 is assigned to relative humidity with default scale 0-100 %RH.
By default the output OUT2 is assigned to temperature with default scale 0-100 °C.
The output assignments and scales can be changed by Modbus commands.

Sensor probe handling
The sensor probes HT-RP16 and HT-RP16H are equipped with a hydrophobic microporous
PTFE filter to protect the sensor from dust, dirt and water drops. The round filter is
snap-fitted and may be replaced if it gets strongly contaminated.
To replace the PTFE filter, carefully hook the filter near it’s edge with a small flat
screwdriver and pull it off. Place a new filter onto the sensor opening and press it to snap
into the groove.
Note! Never stab or press the filter near its center where the sensor is located, as this may
damage the sensor. Do not remove the filter as it may cause the device to show incorrect
values and/or break the sensor.
The recommended orientation of the sensor probe is vertical with the sensor tip pointing
downwards. This prevents possible accumulation of condensed water on the sensor
protection filter. The horizontal orientation is also suitable. Avoid upward position of the
sensor tip.
After replacing the sensor probe check if the M12 connector is securely tightened to
ensure appropriate electrical contact and protection.
