WSS-311 WSS-411 WSS-511 Bimetallic temperature gauge

Overview of WSS-311 WSS-411 WSS-511 Bimetallic temperature gauge

WSS series bimetal thermometer is a field detection instrument for measuring medium and low temperature. Bimetallic thermometer can straight measure the temp of liquid, vapor and gas medium in the range of - 70 ℃ ~ & 500 ℃ in various production techniques.

Bimetal thermometer includes two metals with various linear expansion rapport, and one conclusion is fixed. Any time the temperature changes, the thermal development of the 2 alloys is different, which drives the tip to deflect to point the temp. This is certainly bimetal linen thermometer, as shown in the physique on the above page. The temp measurement range is - 80 ~ 500C, which is suited to temperature dimension when the reliability requirement is not rich in industry. Since a temperature realizing element, bimetallic linen can be used for programmed temperature control.

Working basic principle

WSS-311 WSS-411 WSS-511 Bimetallic temperature gauge uses the hot bimetallic linen wound into a thread as a temperature sensing as well as puts it in the protective sleeve. A single conclusion is set, which is called the fixed conclusion, and the other conclusion is linked to a thin shaft, which is called the free end. A tip is attached to the free conclusion line shaft. Once the temperature changes, the free conclusion of the temperature realizing device rotates, generating the pointer on the fine base to change the angle, and suggesting the related temp on the call.

Features of WSS-311 WSS-411 WSS-511 Bimetallic temperature gauge

Bimetallic temperature gauge has the benefits of fast response, small volume, good linearity and stability. Several foreign products also have high-temperature working performance.

The thermoelectric potential of bimetal thermometer is just related to the thermoelectric property of thermoelectric electrode material and the temperature variation between two comes to an end.

Using the same homogeneous conductor or semiconductor to form a circuit will not produce energy potential.

The two contact temperatures of the thermocouple are t and t0. If t sama dengan T0, the thermoelectric potential of the thermocouple is no. The intermediate temp law lays a foundation for the formulation of thermocouple graduation table.

Regarding many years, researchers have tried to study whether the relationship involving the temp of the conclusion (measuring end) of the thermocouple and the thermoelectric possible created by the thermocouple loop can be expressed by functional relationship or even piecewise perform, nevertheless they failed in the end.

When the two conductors A and M form thermoelectricity with the 3rd director respectively, there is a wide temp measurement range and stable physical and chemical properties for long-term use

Large conductivity and low resistance temperature pourcentage; ※ The set up thermoelectric potential has high sensitivity, geradlinig relationship between thermoelectric potential and temp, easy replication, simple process and low price.

Nevertheless , the compensation bridge of Ni Cr National insurance Si is mistakenly used, and the balance point of the compensation connection is 0º C。 When the cool conclusion temperature is 30 & ordm; C. The temp indicated by the thermometer is nine hundred & ordm; D. Very best actual temp of the heat furnace? The standard electrode law can be used to determine the elements that fluctuate with temperature.
