E2218
Rev 14.05.2021
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.
