8311 Pressure Transmitter/Switch
Brand: Burkert Fluid Control Systems
This intelligent mini transmitter/switch with an extra-large display is specially designed to switch alarms and to establish a monitoring system or an On/Off control loop. The switching points can be programmed with the three-key keypad under the display. In addition, the process value can be transmitted to the PLC (4-20 mA). The connection to the process in the piping is made using standard fittings (G 1/2", 1/2" NPT, Rc 1/2").
Features- Indication, monitoring, transmitting and continuous or On/Off control in one device
- Output signal 4-20 mA, 2-wire for continuous control
- Transistor or relay outputs for On/Off control or alarm function
