Description

The TPK glass mercury electrocontact thermometer is designed to measure temperature and issue single-position control signals when a given temperature is reached.
Thermometers are manufactured with a scale plate made of milky glass inserted inside the glass shell, magnetic adjustment of the position of the working contact within the measuring range, immersed lower part. The form of production is straight. Temperature measurement range from 0 to 200oC. Scale division value, 2oC. Limit of permissible absolute error, ±2oC.
Thermometers must be connected through an amplifying device in accordance with clause 1.1 of GOST 9871-75. Switching power is not more than 1 VA at a current strength of not more than 0.04 A and a voltage of not more than 220 V. Thermometers can operate for direct and alternating current with a frequency of up to 50 Hz.
