The Reverse Mount LPC420 allows for viewing of the level display with the dead front door closed, as well as open. Settings and connections are made on rear of unit.
The Level Probe Converter senses liquid level and provides a 4 to 20 mA analog output for use by a pump controller or PLC to control liquid level. The unit monitors the ten electrodes on a Level Probe, and provides an analog signal that is proportional to level. The unit also provides 10 Relay Outputs with contacts that close as the liquid covers the respective Level Probe electrodes. The Relay Outputs may be used for pump control, level alarms or telemetry.

Additional Description

N/A All setup is easily done using the four DIP switches on the unit. The Sensitivity of the unit must be set for the type of liquid being detected. The Analog Output Delay setting provides control over how fast the analog output transitions from one level output value to another. It takes 10 times the Analog Output Delay setting value to go from 4 to 20 mA, when the electrodes are covered quickly. When the electrodes are slowly covered one at a time, the Analog Output Delay is used to provide a smooth transition as the level goes from electrode to electrode.

Typical Applications

N/A For use with any 10 electrode conductance probe where an analog 4 to 20 mA level signal, relay outputs and a panel mounted level display are required.
