Intrinsically Safe Temperature Sensor type ICT
The intrinsically safe temperature sensor type ICTis used to measure the temperature of gases, liquids and solids in equipment, tanks, pressure piping etc.
This sensor can be used in hazardous areas at risk of gas and dust explosion classified in group I (methane, coal dust) and in group II. The device is equipped with an analogue output of 4-20 mA.
