  • Q:

    All we need is a signal at low level to turn off a polymer pump. Can this be wired to a switch to cut power to the pump at a programmed level with the ultrasonic probe only or is a plc necessary?

      This is an ultrasonic level transmitter. It is constantly measuring the level of fluid and transmitting that via 4-20mA analog output. You could connect this to a PLC and program the PLC to turn off the pump at your selected level. An easier and less expensive method would be to use the 07506-17 switch/controller. This comes with 4 SPST relays to be configured as you require.
