It operates as a constituent part of software-hardware tools of main pipelines and converts the temperature of external surface of pipelines, soil (including explosion hazard zones) into 4–20 mA current signal.

High precision of conversion at operation conditions without adjustment during its service life, capability to operate in severe environment, possibility of self-testing, galvanic isolation of output circuits from power supply and check-out circuits.

Description

The sensor consists of:

measuring transducer IKLZh.405511.001-06 (MT);
measuring probe IKLZh.405212.002 or IKLZh.405212.003 (MP) in compliance with the

Table
The description of MT and MP composition and operation are presented in IKLZh.405511.001RE and IKLZh.405212.002RE (IKLZh.405212.003RE) respectively.
