    Product Details


    Flameproof temperature transmitter is used to measure the temperature of the measured medium by the characteristic that the resistance of platinum resistance changes with the temperature and presents a certain functional relationship. This product uses high-precision thermocouples and thermal resistors as detection elements, and uses highly stable circuits for signal processing to achieve continuous temperature measurement, output industrial control standard signals, and achieve display, remote transmission and other functions. The temperature measurement part of the product adopts the full stainless steel integrated processing technology, and the junction box adopts the explosion-proof housing. The product has the characteristics of strong seismic resistance and fast thermal response; The conductor is a special shielded conductor with a wide temperature range; The product is easy to install and suitable for various automatic control systems of temperature measurement.
