The electric contact double metal thermometer is used for driving the contact change when the temperature changes, and the relay action in the circuit can be automatically controlled and the alarm can be controlled automatically when the contact and the upper and lower contacts are contacted or disconnected.

application

The electric contact thermometer is used in the production field to control the temperature and alarm automatically. Direct measurement of the range of -80 ~ 500 C in the production process, steam and gas medium temperature.

The characteristics of electric contact thermometer:

Field display temperature, intuitive and convenient;

With automatic cut-off power supply and alarm function;

Safe and reliable, long service life;

A variety of structural forms, can meet different requirements.

technical parameter

matters needing attention

1, the range of use: -50-50; -20-80; 0-50; 0-100;; 0-120; 0-150; 0-200; 0-300; 0-400; 0-500; special can be customized.

2, the installation of Luo teeth (movable teeth and fixed teeth can be customized) 27 x 3/4; 2mm; 1/2; 1/43: suitable for ambient temperature -40 ~ +85 C, relative humidity 5 ~ 100%. 4: Dial diameter: 100mm, universal mounting type. Four, use and maintenance

3, double metal thermometer in storage, use and installation should be to avoid collision supporting pipe, never make the supporting pipe bending deformation and the watchcase wrench.

4, various types of dual metal thermometer should not be used to measure the temperature of the open container, charged contact thermometer, do not allow the work under strong vibration, so as not to affect the reliability of the contact point.

5, when the pressure is greater than 1.5MPa, should use JX series of protective tube.
