Guide rail type temperature transmitter is the input single or double thermal resistance, thermocouple signal into output isolation of single or double line of current or voltage signal, and improve the electrical isolation performance between input, output and power supply. Guide rail temperature transmitter can be used with unit combination instrument and DCS, PLC and other systems, in petroleum, chemical, manufacturing, electric power, metallurgy and other industries of major engineering has a wide range of applications. 1, system transmission accuracy: ±0.5%×F·S ±0.2%×F·S 2, working environment temperature: -10~55℃ 3, measurement of thermal resistance allowed lead resistance: ≤15 ω 4, cold end compensation temperature accuracy: 1℃(preheating time 30 minutes) 5, current output allowed external load impedance: 4-20 ma: 0 ~ 350 Ω; 6, voltage output internal impedance: 250 ω 7, input/output/power/communication/double circuit insulation strength: DC DC≥2000V.
