Product description:

properties

Single or dual input thermocouple, heat resistance signal, single or double line analog output isolation of current or voltage signal, and improve electrical isolation between input, output, power performance.

Technical characteristics

This product USES the advanced digital technology, with the traditional analog instrument does not have a number of advanced performance, in both the restraint of the high and low frequency interference signal with excellent performance, even can still reliable application in high power frequency conversion control system, at the same time, the application of digital technology completely overcomes the drawback of traditional linear differential temperature transmitter, internal adopt digital calibration, not zero and full automatic potentiometer, automatic zero dynamic calibration, temperature drift compensation and so on many advanced technologies, and accord with IEC61000-4 - now defined in 95 the fourth class () bad industrial site environment of anti electromagnetic interference for the product, this series of technical application make the stability and reliability of the product guarantee of science.

This product is also adopted the measurement, the output value of synchronous LCD digital display technology, can online observation of actual input and output value theory, at the same time realize the online fault diagnosis, the above technology leading the international advanced level.
