Adjustable Flexible Probe Level Switch

The ENT7 Capacitance Level Switch is intended for high or low level detection of free-flowing powders and granular materials in silos and hoppers etc.
The instrument is completely self-contained, requiring only a supply voltage and having a set of independent voltage-free changeover contacts for connection to external control equipment or alarms.
The unit operates on the principle of a changing electric field caused by the presence or absence of material around the probe. This change is used to operate the output relay. An internal Failsafe Switch offers the option of  failsafe for either high or low level alarms, LED indicators show the state of the output relay. A multi-turn Sensitivity Control allows accurate adjustment of the switch point.The ENT 7 is suitable for top mounting into a 1½” BSP socket.

The 3 metre long probe is 6mm Ø PVC covered stainless steel flexible cable with an adjustable stainless steel weight assembly.
