Guideway temperature transmitter is the input single or double channel thermal resistance, thermocouple signal to output isolated single or double route current or voltage signal, and improve the electrical isolation between input, output and power. Guideway temperature transmitter can be used with unit combination instrument and DCS, PLC and other systems, in petroleum, chemical, manufacturing, electric power, metallurgy and other major projects have a wide range of applications. 1, the system transmission accuracy: ±0.5%×F·S ±0.2%×F·S 2, working environment temperature: -10~55℃ 3, the measurement of thermal resistance allowed lead resistance: ≤15Ω 4, cold end compensation temperature accuracy: 1℃(preheating time 30 minutes) 5, the current output allowed external load impedance: 4-20 MA: 0~350Ω; 0-10 Ma: 0~700Ω If larger load capacity is required, please specify when ordering 6.
