Conversion of ground temperature in the range of -40 до +80°С into a unified output DC current signal of 4–20 mA. It can operate in explosion hazardous zones.

Area of application

In automatic systems operating at main pipelines.

Description

Temperature sensor comprises a copper temperature probe (CTP) as operating primary transducer with a unique sensor curve (USC 50M) according to GOST 6651-94, a conditioning amplifier and can also include up to two additional sample CTP installed in in a molded steel housing.

Distinctive features are high accuracy of conversion in rigid operation environemnt during service life, connection via a 2-wire communication line, possibility of control that does not require dismounting.
