WSSP series The thermal resistance of remote bimetal thermometer And the development of a series of temperature instruments, to overcome the traditional thermometer single expansion performance and short service life and poor reliability, the disadvantages of large volume temperature package. The 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:
WSSP series The thermal resistance of remote bimetal thermometer Is a kind of thermal resistance temperature sensor and WSSP type thermometer temperature package installed in the same temperature element within a temperature measuring instrument. Two measurement systems are independent of each other, do not affect the temperature measurement accuracy and their. The outstanding advantages of this instrument is just a single point temperature measurement can double indicate the measured temperature, the pressure for the instructions, the thermal resistance signal for transmission to the control room (about 500 meters), with two meter line, to control and adjust the measured temperature, the two temperature measurement system to monitor each other, improve the temperature measurement accuracy and reliability.
Three, application:
WSSP series The thermal resistance of remote bimetal thermometer Not only meet the temperature requirements, but also to meet the needs of long-distance transmission, remote double metal thermometer can directly measure the production process in a variety of -40 ~ +600 temperature range of liquid, gas and steam medium and solid surface temperature measurement.
Four, main features:
1, a temperature probe of small, high sensitivity, linear scale, long service life etc..
2, with remote output resistance signal (PT100), shock resistance, corrosion resistant function and large power switch signal etc..
3, structure and international similar products, can replace imported.
Five, technical parameters:
1, the temperature range of -40 to 600 DEG c;
2, the ambient temperature of -10 to 55 DEG c;
3, the relative humidity is less than or equal to 95%;
4, precision grade 1.5;
5, the time constant is less than or equal to 60S;
6, the probe voltage is less than or equal to 6Mpa;
7, probe diameter: 8-10mm diameter, movable external thread: M27*2;
8, thermal resistance PT100 (single channel, dual output or 4-20mA output current).

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 Forty Second, 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:

Ten, the selection of encoding:

Cases: The axial type, PT100 type, I temperature range of 0-400 DEG c.. Activity thread M27x2, protective tube insertion length is 316 300mm. WSSP-401 0-400 l=300mm I: C protection tube 316.

The design and selection of notes:
1, model;
2, the thermal resistance index number;
3, the thermal resistance precision grade;
4, double metal thermometer precision grade;
5, temperature range;
6, fixed form;
7, protection tube material;
8, the inserted length.
