Bimetallic Pointer Temperature And Humidity Meter

Product Details


WSS series bimetal thermometer is a kind measuring middle-temperature, low-temperature field instrument, is widely used in petroleum, chemical, electric power, printing dyeing industry production process

Electrification contact bimetal thermometer can automatic control signal or give a alarm when the measured temperature reach set value

Maintenance precautions:

Before using the thermometer should check the expiration date, if it has been out of date, expired, it need to re-examined, under normal use, s thermometer should be regularly inspected, usually every other year, test one for suitable 

Bimetal thermometer's sensor immerse in the measured medium, and the immersion length must be greater than 100mm (0 to 50ºC range immersion length is greater than 150mm), in order to ensure the accuracy of measurement 

Bimetal thermometer should avoid the collision and impact in any case, not to make the temperature sensor bending deformation, strictly prohibit taking the meter as the wrench tighten screw

Thermometer regularly working temperature should be in the measured

temperature range's 1 / 2 to 3 / 4

For measuring large flow or strong corrosive medium, it should be additional protection tube before using 

Electrification contact bimetal thermometer should not use in the great vibration occasion
