General intelligent temperature transmitter input single or double channel thermocouple, thermal resistance signal, transfer output isolated single or double route current or voltage signal, and improve the electrical isolation performance between input, output and power supply. General purpose temperature transmitter adopts digital technology, has a number of performance that traditional analog instrument does not have, has excellent performance in the inhibition of high and low frequency interference signals, even in the high power frequency conversion control system can still be used reliably, at the same time, the application of digital technology overcomes the traditional temperature transmitter linear shortcomings, Internal use of digital adjustment, zero and full degree potentiometer, automatic dynamic zero calibration, temperature drift automatic compensation and many other advanced technologies, And in line with IEC61000-4-4:1995 in the provisions of the fourth class (harsh industrial site) environment on the product anti-electromagnetic interference requirements, the application of this series of technology makes the stability and reliability of the product scientific guarantee. Applicability universal temperature transmitter can be used with unit combination instrument and DCS, PLC and other systems, in the oil field, petrochemical, manufacturing, electric power, metallurgy and other major projects have a wide range of applications. System transmission accuracy: ±0.2%×F·S Temperature drift: ≤0.0015%F·S/℃ cold end temperature compensation accuracy: ±0.1% when measuring thermal resistance allowed lead resistance: ≤50Ω operating temperature: Industrial standard -10 ~ +55℃ current output allows external load impedance :4-20mA output when 0~500Ω; For 0-10mA output, 0~1KΩ needs greater load capacity.
