ATEX certified temperature and humidity transmitter COMET T3110Ex

ATEX certified relative humidity temperature transmitter. Outdoor, indoor use.

Built-in relative humidity, temperature sensors. Measured values are also converted to other humidity interpretation: dew point temperature, absolute humidity, specific humidity, mixing ratio, specific enthalpy.

ATEX certification for use in potentially explosive environments.

The transmitters T3110 are designed for measurement of ambient temperature and relative humidity of air without aggressive substances. Measured values are converted to other humidity interpretation: dew point temperature, absolute humidity, specific humidity, mixing ratio, specific enthalpy.

Measured and computed values are displayed on a two-line LCD display. The first line displays temperature (ºC / ºF). Value displayed on the second line is selectable among relative humidity and computed value. It is also possible to display both readings with cyclic overwriting (4 seconds interval) or to switch off the LCD display at all.

The transmitter communicates by means two galvanically separated current loop 4-20mA. Each loop has two-wire connection and each loop requires power from evaluation device. It is always necessary to connect loop I1 which is designed for supplying of measuring part of the device. Using the configuration software can be assigned to each current loop any measured or computed value.

All transmitter setting is performed by means of the PC connected via the optional SP003 communication cable (not included in delivery). Using TSensor software (see www.cometsystem.com) you can assign to each output any measured or computed value and to set its measuring range. It is also possible to assign both outputs to the same value (with the same range), if two evaluation devices are necessary to connect. The program supports make the adjustment of the device too. This procedure is described at file „Calibration manual.pdf“ which is installed commonly with the software.

Transmitter T3110Ex is designed and certified for use in hazardous areas. In compliance with European Directive 2014/34/EU (ATEX) the T3110Ex transmitter conforms to European Standards EN 60079-0:2018 and EN 60079-11:2012.

Transmitter is suitable for use in potentially explosive atmospheres (Apparatus Groups llC) in applications requiring devices category 3G.

Type Examination Certificate number FTZÚ 13 ATEX 0189X is available.
