Rail type temperature transmitter

A rail type temperature transmitter is a device that converts input single or dual thermal resistance and thermocouple signals into output isolated single or dual linear current or voltage signals, and improves the electrical isolation performance between input, output, and power supply. Rail type temperature transmitters can be used in conjunction with unit combination instruments, DCS, PLC and other systems, and are widely used in major engineering projects in industries such as petroleum, chemical, manufacturing, power, and metallurgy.

The installation position of the guide rail temperature transmitter shall not have strong vibration, as well as electromagnetic interference from the signal end, power supply end, and space exceeding the intensity of Class III industrial site electromagnetic interference in IEC61000-4-4:1995, and there shall be no harmful substances that seriously corrode metal and plastic parts in the operating environment.

3、 Selection instructions

1. Input signal type

Thermocouple: K E、S、B、J、R、N、T

Thermal resistance: Pt100 Cu100、Cu50、BA1、BA2

When selecting the input signal type for the guide rail temperature transmitter, users should inform the temperature range requirements corresponding to the input signal, so that the product can be debugged properly when leaving the factory. Other input and output types will be customized separately;

2. Single loop input * * * can have two outputs, and each dual loop input can only correspond to one output;

3. If you need different input signals for dual circuit products, please contact our company;
