Product Introduction
WSS series bimetal thermometer is a kind of field detection instrument for measuring medium and low temperature. Bimetallic thermometers can directly measure the temperature of liquid, steam and gas medium in the range of -80 ° C to +500 ° C in various production processes.

Principle Structure
Bimetal thermometer is wound into a threaded shape of the hot bimetal sheet as a temperature sensing device, and it is installed in the protective sleeve tube, one end is fixed, called the fixed end, the other end is connected to a thin shaft, called the free end. The free end spool is provided with a pointer. When the temperature changes, the free end of the temperature sensing device will rotate accordingly, driving the pointer on the thin axis to produce an Angle change, indicating the corresponding temperature on the scale.

Sort
According to the connection direction of the bimetal thermometer dial and the protective tube, the bimetal thermometer can be divided into four types: axial type, radial type, 135° type and universal type.
① Axial bimetal thermometer: the dial is connected to the protective tube vertically.
(2) Radial bimetal thermometer: the dial is connected with the protective tube in parallel.
(3) 135° directional bimetal thermometer: the dial is connected to the protection tube at 135°.
④ Universal bimetal thermometer: the Angle of connection between the dial and the protective tube can be adjusted arbitrarily.

Fixed Form
In order to meet the needs of actual production, bimetal thermometers have different mounting and fixing forms: movable external threaded pipe joints, movable internal threaded pipe joints, fixed threaded joints, sleeve threaded joints, sleeve flange joints and fixed flanges.

Peculiarity
The biggest advantage of bimetal thermometers is that they have good seismic performance and are strong, but their accuracy is low and can only be used in industry, with an accuracy level of 1 to 2.5.
Bimetal thermometer is suitable for medium and low temperature field detection, can directly measure the temperature of gas, steam and liquid, indicating clear value, good mechanical strength.

Common Type
General bimetallic thermometers have the following types:

Outdoor type, heavy duty

Main technical parameters:
(1) Accuracy level: 1.5
(2) Time constant: J < 40S
(3) Protection pipe pressure: 6.3MPa

Electrical contact type
Bimetal thermometer is a kind of field instrument suitable for measuring low temperature, which can be directly used to measure the temperature of liquid and gas.
Main technical parameters
(1) Accuracy level: 1.5
(2) Time constant: J < 40S
(3) Protection pipe pressure: 6.3MPa
(4) Contact capacity: rated power 10VA (non-inductive); Maximum voltage: AC 220V, maximum working current: 1A(non-inductive),
The contacts are upper and lower limits and usually open.
(5) Table head working environment temperature: -25~55 degrees Celsius

Shock-proof type
WSSXN series vibration-resistant bimetal thermometer with electric contact is a kind of field instrument for measuring medium and low temperature. It can directly measure the temperature of liquid, steam and gas medium and harsh and vibrating environment in the range of -80℃ ~ +500℃ in various production processes.
The vibration-proof electric contact bimetal thermometer is filled with vibration-proof oil from inside the instrument, which can effectively overcome the pointer jitter caused by mechanical vibration. In the design principle and structure, it has the characteristics of waterproof, anti-corrosion, shock resistance, intuitive, easy to read, no mercury damage, strong and durable, and is widely used in petroleum, chemical industry, machinery, shipbuilding, power generation, textile, dyeing and other industries and scientific research departments.
Main features:
(1) On-site temperature display, intuitive and convenient, safe and reliable, long service life;
(2) A variety of structural forms, can meet different requirements, no mercury damage, easy reading, strong and shock-resistant;
(3) The protection pipe is 1Cr18Ni9Ti stainless steel and molybdenum dititanium, which has strong pressure and anti-corrosion ability; (4) The core type thermometer may not be shut down for short maintenance or replacement of the movement.

How It Works
Bimetallic thermometers with shock-resistant electric contacts are based on a bimetallic sheet wound to make a circular bend. When one end is heated and expanded, the pointer is driven to rotate, and the working instrument displays the temperature value, and the bimetal thermometer is filled with silicone oil or the display part of the bimetal thermometer is separated from the measuring part to achieve the effect of shock resistance.
The shock-resistant bimetal thermometer is divided into two kinds: the integrated shock-resistant bimetal thermometer and the separated shock-resistant bimetal thermometer.
Main technical parameters:
(1) Implementation standard: JB/T8803-1998 GB3836-83
