Productoverview:
WSSX series Electric contact remote double metal thermometer Is wound into a double sheet metal ring bent on. At the end of heating expansion, drives the pointer to rotate, the instrument will display the temperature value, and prevent environmental vibration in double metal thermometer internal filling silicone oil or double metal thermometer display separation part and a measuring part to achieve the seismic effect. Electric contact bimetallic thermometer and integrated seismic electric contact bimetallic thermometer and separate seismic electric contact bimetallic thermometer 2.
Two, work principle:
WSSX series Electric contact remote double metal thermometer Electrical contact device with mechanical electric contact.When the medium temperature changes, on the free end of the thin shaft and steering transmission mechanism to drive the movable contact and pointer rotation, indicating in the dial on the change of temperature value, and when the fixed contacts (upper and lower fixed contacts) instantaneous contact or disconnection of the relay and contactor circuit in the system, in order to achieve the purpose of automatic control and alarm.
Three, application:
WSSX series Electric contact remote double metal thermometer Is a measuring instrument used in temperature field production is not very high occasions, can be directly measured gas, steam temperature, temperature measurement at 80 degrees -500 degrees below zero within the scope of the paragraph from the design has the characteristics of waterproof, corrosion resistance, shock resistance, intuitive readings, sturdy and durable, widely used in petroleum the chemical, ships, machinery, power, textile, printing and other industrial occasions.
Four, main features:
1, the scene display temperature, convenient safe and reliable, long service life;
2, a variety of forms, can meet different requirements. Victims of mercury free, easy reading, strong shock.
3, the protection pipe of 1Gr18Ni9Ti stainless steel and two molybdenum titanium, pressure, strong corrosion resistance.
4, core pulling type thermometer can not stop short time maintenance or replacement of movement.
5, integrated with axial type, radial type, 135 type, universal type, complete varieties, suitable for various on-site installation need.
Five, technical parameters:
1, measurement range: -80~40 degrees, -40~80 degrees, 0~50, 100, 150, 200, 250 degrees, or specified by the user;
2, precision class: 1.5;
3, working pressure: Zui pressure 4.0Mpa;
4, F4 coating thickness: ~0.8mm, can also be specified by the user;
5, quality inspection by EDM micro flaw detection, voltage 12KV, frequency of 1.6 * 106Hz breakdown;
6, material: ICr18Ni9Ti; metal protection tube or specified by the user;
7, metal protection tube: phi 6, Phi 8, Phi 10, Phi 12;
8, connecting dimensions: (1) movable external thread: M27 * 2, G3/4, G1/2, or specified by the user;
(2): DN15, 20, flange 25, HG20593, or specified by the user;
9, dial od: D= Phi 80, Phi 100, Phi 150.

Note:
1, in storage, installation, use and transport process, to avoid the collision protection tube, prohibit the protection tube bending and deformation.
2, installation, non twist instrument shell.
3, the instrument shall work normally in the -30 to 80 DEG C ambient temperature.
4, the instrument can often work in the temperature scale range 1/2 ~ 3/4.
5, the protective tube immersionmedium measured in length must be greater than the length of the sensing element, this is done in order to ensure the accuracy of measurement.
6, do not use media exposure in measuring container.
7, the use of the process should pay attention to check in time, probably in about 6 months.

Seven, electrical parameters:

Eight, insulation resistance:

Normal working conditions: air temperature -25-+55 Temperature relative humidity Less than 85 %.
Set point error: set point error should not exceed the basic error limit One . Five Times.
Switching difference: switching error should not exceed the basic error limit One . Five Times.
Nine, technical data sheet:

Ten, the selection of encoding:

Example: universal type, dial diameter Phi 100 The temperature range. Zero ~ Four hundred C, One point five Activity level, external thread M27 * 2 Length. 450mm . WSSX-481 , Zero ~ Four hundred C, L=450 , M27 * 2 , One point fiveClass.

Eleven, Design selection and ordering information :
1, model;
2, precision grade;
3, temperature range;
4, fixed form;
5, the installation form of casing heat;
6, the inserted length.
