Rail Mounted Temperature Transmitter
Rail Mounted Temperature Transmitter isolates and amplifies the signal of temperature sensor (such as thermal resistor and thermocouple), converts it into a DC signal linear with temperature and outputs it to the control system.
Working Principle Of Rail Mounted Temperature Transmitter:
Rail Mounted Temperature Transmitter isolates and amplifies the signal of temperature sensor (such as thermal resistor and thermocouple), converts it into a DC signal linear with temperature and outputs it to the control system. Its sensor input side is electrically isolated from the analog output end, so Rail Mounted Temperature Transmitter is very suitable for fast measurement of thermocouple and thermal resistor.
Rail Mounted Temperature Transmitter can be used with unit combination instruments and DCS, PLC and other systems. It can provide the required measurement range according to customer requirements. The rail mounted temperature transmitter is easy to install and is widely used in petroleum, chemical, manufacturing, electric power, metallurgy and other industries.
Features:
- Strong compatibility
- High precision, millisecond response
- Output overcurrent protection
- Output short circuit protection
- Error signalling in the event of sensor break
- Support multiple input and output
