WSS-310 WSS-311 WSS-410 Bimetallic thermometer

Overview

WSS-310 WSS-311 WSS-410 WSS series bimetal thermometer is an on-site detection instrument for measuring low and medium temperature. The bimetal thermometer can directly measure the temperature of liquid, steam and gaseous media in the range of -80℃～+500℃ in various production processes.

Working Principle

WSS-310 WSS-311 WSS-410 The bimetallic thermometer uses a hot bimetallic piece wound in a threaded shape as a temperature sensing device, and it is installed in a protective sleeve. One end is fixed, called the fixed end, and the other end is connected to a thin shaft, called Free end. A pointer is provided on the free end spool. When the temperature changes, the free end of the temperature sensing device rotates accordingly, driving the pointer on the thin shaft to produce an angle change, and the corresponding temperature is indicated on the dial.

Features

WSS-310 WSS-311 WSS-410 bimetallic thermometer

The thermoelectric potential of the bimetal thermometer is only related to the thermoelectric properties of the thermoelectrode material and the temperature difference between the two ends.

Using the same homogeneous conductor or semiconductor to form a loop will not generate thermoelectric potential.

The two junction temperatures of the thermocouple are T and T0. If T=T0, the thermoelectric potential of the thermocouple is zero. The law of intermediate temperature lays the foundation for the formulation of thermocouple index tables.
