8400 Screw-In Temperature Sensor/Switch
Brand: Burkert Fluid Control Systems
This intelligent sensor/switch with an extralarge display is specifically designed to switch a valve and to establish a monitoring system or an ON/OFF control loop.
Compact and wall versions are available. The wall-mounted version must be inserted into a holder previously mounted on a wall, and it must be associated with a remote temperature sensor.
The switching points can be programmed with the 3 key pads or optionally, with input 4-20 mA, from an external PLC over a 4-20 mA loop. As an option, the process value can additionally be transmitted to the PLC (4-20 mA).
The connection of the 8400 to the process in the piping is made using standard fittings.
Features- Indication, monitoring, transmitting and On/Off control in one device
- Extra-large display
- Menu-guided parametrisation
- Complete control loop with external setpoint
