The electrical contact bimetal thermometer uses the change of the contact point when the temperature changes. When it contacts or disconnects with the upper and lower limit contacts, the relay in the circuit is actuated, thereby automatically controlling and alarming.
Precautions
1. Use range: -50-50°C;-20-80°C;0-50°C;0-100°C;0-120°C;0-150°C°C;0-200°C;0-300°C;0 -400; 0-500 °C can be customized.
2, the installation of screw teeth (mobile teeth and fixed teeth can be customized) 27 × 2mm; 3/4; 1/2; 1/43: applicable to the ambient temperature -40 ~ +85 °C, relative humidity 5 ~ 100%. 4: The dial diameter is: 100mm, universal installation type. Fourth, use and maintenance
3. In the storage, use and installation of bimetal thermometers, collision with the support tube should be avoided. Do not bend the support tube and use the case wrench.
4. All kinds of bimetal thermometers should not be used to measure the temperature of the medium in open containers. The live contact thermometer should not be allowed to work under strong vibration, so as not to affect the reliability of the contacts.
5, when the pressure is greater than 1.5MPa, JX series protection tube should be used.
Use maintenance
1. During the storage, installation, use and transportation of WSS series bimetal thermometers, collision protection tubes should be avoided as far as possible. Do not bend or deform the protection tube. Do not twist the meter housing during installation.
2. The meter should work normally within the ambient temperature of -30°C～80°C.
3, the temperature of the instrument often works best in the scale range of 1/2 to 3/4.
4. The length of the bimetal thermometer protection tube immersed in the measured medium must be greater than the length of the temperature sensing element. Typically, the length of the bimetal thermometer protection tube is greater than 100mm, and the immersion length of the 0-50°C range is greater than 150mm to ensure the accuracy of the measurement.
5, all kinds of bimetal thermometers should not be used to measure the temperature of the medium in open containers, live contact thermometers should not be used in the control loop of the occasion where the work vibration.
6. In the storage, use, installation and transportation of bimetal thermometers, collision protection tubes should be avoided. Do not bend the protection tube and use it as a wrench.
7. The thermometer should be tested regularly under normal use. It is generally appropriate every six months. Electrical contact thermometers are not allowed to work under strong vibrations so as not to affect the reliability of the contacts.
