Usage
These temperature transducers are intended for temperature measurement of firm, loose, liquid and gaseous media and ensure the functioning of recording devices, systems of control and automatic regulation of different purpose.
The temperature transducer is calibrated in accordance with GOST 8.461.
The temperature transducers should be used with protective sleeves
Construction
TThe temperature transducer consists of a sensing element, which is located in a protection tube, and of a cable with the proper section and amount of wires.
The isolation of joining wire tips is removed.Dealing with 4-wire circuit, pairs of wires have different length in acc. with inner connection.

Installation
The resistive temperature transducer is mounted to a pipeline with the help of protection sleeves and weldolets.
If the length of a temperature transducer is from 60 to 250 mm it’s better to use for mounting protection sleeve of design 2 and weldolet БП1(or БП2).
The leaden seal is fixed through a sleeve screw.
Connecting
A connecting with external devices is made with the help of the proper section of a flexible cable and the amount of wires corresponding to the temperature transducer circuit.
