WP-9000 series thermal resistance temperature transmitter
WP-9000 series thermal resistance temperature transmitter is to isolate and convert the on-site thermal resistance signal into a linear DC signal and output it to the control system or other unit combination meters.
Intelligent thermal resistance temperature transmitter. Users can configure and set the thermal resistance type and measuring range through software.
This temperature transmitter needs independent power supply, electromagnetic isolation between power supply-input circuit-output circuit.
● Two-wire or three-wire thermal resistance temperature signal input, isolated transmission output.
● Intelligent, can carry out on-site configuration settings. You can also select a fixed thermal resistance type and temperature range input.
● Modular watch movement design, no need for zero and full scale adjustment, automatic dynamic calibration of zero point, automatic temperature drift compensation.
● With working power indicator.
● Input circuit overcurrent protection.
● Plug and unplug terminal blocks, DIN rail card installation.
