High Accuracy Long Life Temperature Transmitter modbus pt100
temperature sensor
Product introduction:
PPM-WZPB is composed of a temperature sensor and a signal
converter. The signal converter is installed in the cold end
connecting box of the temperature sensor.
The temperature sensor is affected by the temperature to produce a
differential voltage signal.
This signal is amplified by the amplifier, and then through the
voltage and current conversion, then produce a 4-20mA current
signal or other 0-5V signal.
Applications
Petroleum, chemical, metallurgy
machinery, electricity, steel,
glass, ceramics, heat treatment
Features
1. They can measure temperatures of liquid, steam,gas and solid in
producing.
2. Characteristics are shock resistant, high-temperature resistant
and long life.
3. Used for temperature measuring and automatic controlling in
scope from -200 to 600ºC.
