Productoverview:
WTZ-280 series Electric contact pressure type thermometer Suitable for the measurement of copper and copper alloys do not corrode liquid, gas and steam temperature, and can reach or exceed a given value when the temperature signal, the electric contact pressure type thermometer can also be used as the temperature control circuit contact switch in the system. Anti-corrosion type adopts stainless steel material, the temperature measurement for neutral corrosive gas and liquid.

Two, work principle:
WTZ-280 series Electric contact pressure type thermometer The principle is the relation between evaporation of the liquid in the airtight temperature measurement system based on saturated vapor pressure and temperature, and temperature measurement. Three, application:
WTZ-280 series Electric contact pressure type thermometer Used in the production field of temperature automatic control and alarm. Can the liquid, steam and gas temperature measurement in various production processes of -80 in the range of -+500 DEG C. Suitable for neutral corrosive liquids and gases.

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;
4, electric contact transmission.
Five, technical parameters:
1, time constant: 15S (steam) 30S (gas)
2, contact capacity: 10VA (no sense) Zui high voltage: AC 220V, upper and lower limit contact.
3, the working environment temperature: 10~+55 degrees Celsius
4, indicating the accuracy: 1.5 (range part requirements) 

Sixth, external reference line:
WTZ (Q) -280 series of thermometers on the lower limit of the electrical device contact capacity is 10VA, so each user to solve contact power amplification problem, for the convenience of users, we will have the power amplifier circuit and the arc extinguishing effect of the anti vibration is recommended as follows
Note: the line power amplifier circuit in the lower contact as long as the contact time, the coil loop will enter the self-locking state, and only when the upper contact action of a lower exit loop can be self-locking, so as to realize the protection requirements of electric contact.
