Reliable level alarm and control of liquids and solids

As a liquid or solid rises or lowers around the probe, the capacitance field changes. This is monitored and used to control the two on-board relays.

Each relay includes full differential control to allow the relay to activate and de-activate between two distinct at user determined points on the probe. This can be used for pump and valve control between high and low level points. Adjustable time delay is standard to suppress spurious alarms from turbulence.

Features and Benefits

• Electronics is integral to the probe
• High corrosion resistant Teflon and stainless steel wetted and 316SS parts
• Capacitance technology responds to all product types
• HF capacitance technology does not require routine cleaning
• Easy calibration and control set-up

The electronics for this model can also be mounted remote from the probe. Refer to the Model 2852-LS. The probe becomes Intrinsically Safe when ordered with an IS Barrier installed in 2852-LS control panel: CSA Div 1, Class 1, Groups A,B,C,D

Reliable monitoring for the oil/water interface in separators

The probe is inserted into the separator or sump to the depth of desired oil accumulation. The electronics is calibrated to the capacitance field around the probe. As oil accumulates and displaces the water, the capacitance change around the probe tip is monitored to activate the relays.

Adjustable time delay and sensitivity adjustment is standard to suppress spurious alarms from intermittent turbulence and wash-down.
