COMET T3111Ex Intrinsically Safe Humidity and Temperature Transmitter

Intrinsically Safe Humidity and Temperature Transmitter with Cable Probe, Cable 1m
Programmable transmitters T3110Ex, T3111Ex, T3113Ex with 4-20 mA outputs are designed for measurement of relative humidity and temperature in potentially explosive environments.

Electrical equipments for use in potentially explosive atmospheres Special devices that can be a source of potential danger. Such devices must be designed, installed, operated, and maintained so as to not cause an explosion in potentially explosive atmosphere. The basic information about equipments intended for use in the potentially explosive atmosphere contains 94/9/EC (ATEX) Directive.

Potentially explosive atmosphere
An area, in which could be present a mixture of air and flammable substances (gas, vapor, mist, combustible dust) in such concentration, that it may catch fire. Explosion may be initiated by a spark or hot surface.

T311xEx transmitters are intrinsically safe
It is a way of equipment protection, which is based on the limitation of energy (electrical and thermal) at a level lower than the level that could cause ignition of a specific hazardous atmospheric mixture.

The principle of intrinsic safety equipment
Lies in limitation of the amount of electric energy supplied to electric circuits from power source and energy accumulated into parts of electric circuits. Intrinsically safe zener barriers and intrinsically safe isolation amplifiers are elemental types of intrinsically safe interfaces designed to protect electrical circuits installed in potentially hazardous areas.
