General description The transmitters T3111 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 and specific enthalpy. The transmitters are equipped with an external humidity and temperature probe on a cable.
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 at www.cometsystem.com. IE-SNC-T3111-13...

“Typical application wiring”. For device connection it is recommended to use a shielded cable with a maximum length of 1200m. External diameter of the cable for T3111, T3111P and T3111Ex connection is 4 to 8 mm. For T3311L connection use cable with respect to female connector parameters (do not connect shielding at connector side).
During info mode no measurement and no output current generation proceed. The transmitter stays at info mode 15 s, and then automatically goes back to measuring cycle. The verifying of settings of the T3111Ex transmitter is permitted only in non-hazardous area. IE-SNC-T3111-13...
Error 3 - there is a reading „Err3“ on LCD display upper line. Error of internal A/D converter appeared (converter does not respond, probably damage of A/D converter). No measurement and calculations of values are proceeded. It is a serious error, contact distributor of the instrument. IE-SNC-T3111-13...
