Bimetallic Temperature Meter Automatic Temperature Controller

I.Summary
WSS series bimetal thermometer is akind 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 aalarm when the measured temperature reach set value.

IV.Maintenance Precautions
1. Before using the thermometer should check the expiration date, If it has been out
of date, expired, it need to re-examined; under normal use, sthermometer should be
regularly inspected, usually every other year, test one for suitable.
2. Bimetal thermometer's sensor immerse in the measured medium, and the
immersion length must be greater than 100mm (0 ~50 ºCrange immersion length
is greater than 150mm), in order to ensure the accuracy of measurement.
3. 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.
4. Thermometer regularly working temperature should be in the measured
temperature range's 1/ 2~ 3/ 4.
5. For measuring large flow or strong corrosive medium, it should be additional
protection tube before using.
6. Electrification contact bimetal thermometer should not use in the great vibration
occasion.
