Sarco LP20 Liquid Level Control System

Overview

The Spirax Sarco level control system comprises a LP-20 probe, PA-20 pre-amplifier, and LC2500 level controller. The Level Control System also has a level transmitter and digital display unit available as options.

The LP-20 probe consists of a stainless steel rod completely insulated from the water by teflon. As the water level rises, thecapacitance betwen the rod and the ground boiler protection tube or probe chamber increases. The capacitance is measured by the preamplifier and is transmitted as a dc signal to the controller. Control and alarm levels are set in the controller.

The LC-2500 controller is a dual voltage unit with two channels, designated A and B. Either of the channels can be set to provide a high or low alarm, and Channel B can also provide adjustable on/off control.
