4/20mA 

circuit 

Effectively combining a 4/20mA loop powered temperature transmitter plus a loop 

powered indicator, these instruments accurately display temperature on a large easy to 

read display and transmit an accurate, linear 4/20mA current proportional to 

temperature. Designed for use in all hazardous areas, this range of indicating 

temperature transmitters can be conditioned on-site to operate with most types of 

resistance thermometer and thermocouple.
