Reliable level monitoring of liquids and solids for measurement and control

The unit continuously monitors the liquid or solids level in a tank, stand-pipe or containment. Outputs include analog, digital, and relay control for interface to alarms, valves, pumps and other process monitoring equipment.

The 2852-LT sensing probe monitors the capacitance field around the probe. As the product rises in the tank or vessel the probe capacitance increases. This change is used to provide a 4-20 mA proportional output and two setpoint alarm relays. on can be set using any two points along the probe length.
