ATEX-certified for installation in explosive atmosphere hazardous areas, the COMET T3110Ex transmits humidity, temperature and calculated dew point via a 4-20 mA analogue output. Review the applicable ATEX zone classification, measurement range and process connection requirements to confirm this transmitter meets your site safety standards and instrumentation specifications before ordering.
1 READY TO SHIP
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.
Included in delivery:3 year warranty
NOTE: The COMET T3110Ex 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.
