WSSE series Thermocouple remote double metal thermometer Temperature sensor of steam and gas volume …

Productoverview:
WSSE series Thermocouple remote double metal thermometer Temperature sensor of steam and gas volume respectively than the traditional pressure type thermometer reduced by 30 and 60 times, creatively or platinum copper heat resistance temperature sensor mounted on the measuring element, realize the function of temperature measurement of electromechanical integration. Formed by the liquid pressure type temperature is extremely basic temperature measuring instrument for remote transmission, explosion-proof, anti-corrosion, shockproof, electrical connector, temperature signal transmission and other functions, a series of temperature meter.

Two, work principle:
WSSE series Thermocouple remote 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:
WSSE series Thermocouple remote double metal thermometer The one with the thermocouple, which meet the temperature requirements, but also to meet the needs of long-distance transmission. Can be directly measured in the process of -80 to +500 DEG C range of liquid, steam and gas and solid surface temperature.

Fourth, the main features:
1, the scene display temperature, convenient, safe and reliable, long life and other characteristics.
2, 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, the axial and radial type, 135ordm; type, universal type, complete varieties, suitable for various on-site installation need.

Five, technical parameters:
1, dial diameter: 100, 150;
2, thermal response time: less than 40s;
3, precision grade: 1, 1.5;
4, thermocouple: I II 2.5 C 1.5 C;
5, heat resistance: a + (0.15+0.005ItI) B (0.30+0.005);
6, protection grade: IP55.

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.

Seven, technical data sheet: 

Eight, temperature range:

Remarks：
One The insertion depth of the thermometer, L Must be greater than Lmin , L Alternative series: One hundred , One hundred and fifty , Two hundred , Two hundred and fifty , Three hundred , Four hundred , Five hundred , Seven hundred and fifty , One thousand , One thousand two hundred and fifty , One thousand and five hundred , Two thousand So, also can be customized according to user needs.
Two And the protective tube diameter Phi 6 , Phi 8 The series of thermometers, the time constant is less than FortySecond, diameter Phi 10 When the time constant is less than Thirty Seconds.
Three Protect the stainless steel tube 1Cr18Ni9Ti Manufacturing, at room temperature under high working pressure is Zui 6.4MPa .

Nine, shape and size:

10, encoding selection:

Cases: The axial type, E type, I temperature range of 0-400 DEG c.. Activity thread M27x2, protective tube insertion length is 316 300mm.: WSSE-401 0-400 C l=300mm I 316 protective tube.
Eleven, design and ordering:
