Product details
The WP-9000 series thermocouple temperature transmitter isolates and converts on-site thermocouple or millivolt signals into DC signals, which are transmitted to the control system or other unit combination instruments.
Intelligent thermocouple signal temperature transmitter. Users can configure and set the thermocouple type and range through software.
This temperature transmitter requires independent power supply, with electromagnetic isolation between the power supply input circuit output circuit.
◆ Characteristics
Thermocouple temperature transmitter isolated output.
