ATEX certified humidity and temperature transmitter. Use in potentially explosive atmosphere. Outdoor, indoor use.
Relative humidity, temperature sensors at probe on the cable. 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 device is supplied with T+RH probe with 1 meter cable.
INCLUDED IN DELIVERY:- T3111Ex
- Instruction Manual
- Traceable Calibration Certificate
- FREE software TSensor for Configuring of the Transmitter
3 year warranty
NOTE: The COMET T3111Ex is an intrinsically safe (Ex i) transmitter. Devices with this protection method must be connected through an energy-limiting interface, such as a zener barrier or galvanic isolator, when used with standard control systems. This is a fundamental requirement of intrinsic safety and ensures the device remains compliant for hazardous area use.
