Gems Sensors & Controls CAP-100/-200 capacitive liquid level sensors

Gems Sensors & Controls CAP-100 and CAP-200 Series capacitive liquid level sensors offer a level-sensing solution for a wide variety of bottle types including plastic, glass and fibreglass. These compact sensors are suitable for medical applications such as waste, reagent or diluent liquids as well as dark, sticky or viscous fluids. Easy to calibrate, both sensor series are available in both aqueous and non-aqueous versions and can be delivered with factory preset sensitivity for quick installation for OEM orders. They may also be used as a proximity sensor to detect the presence of solids such as paper or pulp.

The two series are distinguished by their mounting method. The CAP-100 Series is a non-contact sensor that mounts to exterior of non-metallic tanks and bottles with wall thicknesses up to 15 mm thick.

CAP-200 Series mount via a threaded ½″ NPT boss in either metallic or plastic vessels. Made with Delrin bodies, the CAP-200 is suitable for food and beverage application without the need of a sensor well. Both series are available in models that support either aqueous or non-aqueous liquid detection, with a choice of wet- or dry-sink switch actuation.

Both series are compact. The externally mounting CAP-100 measures 57 x 30 mm, while the CAP-200 is 52 mm long. They incorporate LED signal and power indicators. An integrated potentiometer allows sensitivity field adjustments. A 10-48 VDC supply voltage is required for operation.
