Product details
The WP-9000 series thermistor temperature transmitter isolates and converts the on-site thermistor signal into a linear DC signal with temperature, and outputs it to the control system or other unit combination instruments.
Intelligent thermal resistance temperature transmitter. Users can configure and set the type and range of thermal resistance through software.
This temperature transmitter requires independent power supply, with electromagnetic isolation between the power supply input circuit output circuit.
