Thermal resistance temperature transmitter products are mainly used for the isolation and transmission of Pt100, Pt1000, Pt10, Cu50, Cu100 and other sensor signals (the sensor needs to be configured by the user). It is mainly used to measure the temperature of -200 ~ + 600 ℃ in the industry. . The transmitter has linearization and long-line compensation functions, and is calibrated according to the Pt100 national standard index table when it leaves the factory, which fully meets the 0.2 level accuracy requirements. The input, output and auxiliary power supply are completely isolated (three isolations) and can withstand an isolation voltage of 2500VDC. The product adopts DIN35 international standard rail mounting method, with small size, high accuracy, stable performance and high cost performance, and can be widely used in petroleum, chemical, power, instrumentation and industrial control industries.
The temperature signal isolation amplifier is very convenient to use. Just connect the wire to realize the isolation and transmission of the thermal resistance signal.
