Thermometers electrocontact TPK-U (angular)

DESCRIPTION
Electrocontact thermometer.
The thermometer is intended for the alarm system about achievement of the set temperature or maintenance of any temperature within a working scale in various installations.
9871-75 are made in accordance with GOST.

DESIGN Connecting contact from a platinum wire is sealed in a thermometer capillary; executive contact - the lower end of a tungsten wire which is fixed on the mobile nut which is put on the microscrew can move to the channel of a capillary by means of the magnet rotating the microscrew up and down. On the enclosed school plate from glass of dairy color two scales are put: top serves for preliminary setup of the thermometer for the set temperature (under the provision of the lower cut of a mobile nut on a scale); lower - for a control correcting by position of a sting (the lower end of a tungsten wire) counted on a scale and the indication of the control thermometer.
Works in chains of direct and alternating current in the bezyskrovy mode. The allowed electric loading on contacts no more than 1 VChA at current no more than 0,04 And yes at a tension on contacts no more than 220 Century. Length of the top part is 355±10 mm Length of the top part of the thermometer: 355±10 mm Length of the lower part of the thermometer: 141, 201, 291, 441 mm Diameter: 18±1/9±1 mm. Thermometric liquid: mercury.
