Product brief introduction: armoured type integrated temperature transmitter is composed of low power two-wire temperature transducer and temperature sensor ( thermocouple heat resistance ). It has the following characteristics: 1can be installed at the site, direct output from 4 to20mA signal; it can solve the thermocouple or thermal resistance is unable to realize the remote transmission, and transmission loss; it can obtain accurate measurement results, and eliminates the bad contact between sensor and transmitter terminal the signal uncertainty ( the the thermal resistance is particularly important ); the two-wire system wiring method, transmission lines, and the canceling of the more expensive wire compensation, has convenient installation and maintenance, installation cost; adopt armored temperature measuring element, pressure, seismic, stable and reliable work, long service life; the protective tube and the temperature measuring element is a separable structure, can carry out rapid replacement of temperature measuring element, realize non-stop, repair; protection tube forms and diverse material, can meet the high temperature, high pressure and strong corrosive medium temperature measuring requirements; the it has both the assembly type thermocouple heat resistance and low price advantage, and integrated temperature transmitter with remote signal output from 4 to 20mA, anti interference signal is strong and easy installation and maintenance, suitable for non critical location of the temperature measurement.

When the selected integrated temperature transmitter, because from the heat source is close, the working environment temperature may be higher, measures should be taken to prevent the junction box, working temperature exceeds the allowable value of 85 ℃.

When the temperature upper limit of 500℃, protection tube exserted length increased from 150mm to250mm.

When the temperature upper limit of 800℃, should do the measurement position insulation measures, prevent radiation of heat caused by the junction box temperature high.
