Description:
Productoverview:
WSSF series Anti-corrosion type double metal thermometer Is a kind of field measurement, suitable for low temperature detection of industrial instrument can be used to directly measure the gas, liquid and steam temperature.Electric contact bimetallic thermometer can exceed the given values in the temperature, automatically sends out control signal to cut off power supply or alarm.
Double metal thermometer has advantages of no mercury damage, easy reading, sensitive reaction and solid proof, can replace the industrial glass mercury thermometer, widely used in industrial and scientific research departments.Anticorrosion type instrument shell using Aluminum Alloy three spray paint or coating, protection tube, connecting columns made of 316L material, the connecting part adopts the sealing pad, temperature measurement can be applied in the most corrosive medium, gas.
Two, work principle:
WSSF series Anti-corrosion type double metal thermometer Is the principle of expansion work in varying degrees of temperature change when using two different metals. Industrial use of double metal thermometer main element is one with two or more metal sheet laminated together to form a multilayer metal sheet. In order to improve the measurement sensitivity of double metal thermometer, usually made of sheet metals of spiral shape. When the multilayer metal sheet temperature changes, each layer of metal expansion or shrinkage range, so that the spiral rolled up or loosen. Since the end of the spiral coil is fixed and the other end and a pointer can rotate freely. Therefore, when the feeling of double sheet metal to temperature changes, in a pointer to the circular indexing on the gauge indicates the temperature to.
Three, application:
WSSF series Anti-corrosion type double metal thermometer The shell adopts Aluminum Alloy three spray paint or coating, protection tube, connecting columns made of 316L material, the connecting part adopts the sealing pad, temperature measurement can be applied in the most corrosive medium, gas.
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, the implementation of standards: JB/T8803-1998 GB3836-83;
2, dial diameter: ;
3, accuracy: (1, 1.5);
4, thermal response time: less than 40S;
5, protection grade: IP55;
6, adjust the angle error: adjustment angle error should not exceed the range of 1%;
7, return difference: double metal thermometer to the difference should be less than the absolute value of the basic error limit;
8, repeat: double metal thermometer repeatability limit should be less than the absolute value of basic error of 1/2.
Six, matters needing attention:
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.
