Capacitive Level sensors KAS Series 95
For many years, in the field of industrial automation, capacitive Proximity sensors (our abbreviation KAS) have been well accepted as indispensable elements for the level control of most different products. This is true whether the products are liquids, pastes, powder, seeds. grain or granulates. The Sensors are available in a wide range of variants. In the agriculture industry the Capacitive sensors and probes control automatic animal feeding systems and detect fodder and seeds. They serve as a backlog jam indicator in conveying systems or as level control in dosing units, filling or Packaging systems. They control the filling level both in large silos and in small storage containers. Capacitive sensors detect the filling level within agriculture machinery, in the storage Tanks and dosing units, for instance seed, fertilizer, etc. This brochure presents one of our high lights: the series 95 capacitive sensors. Series 95 • Supply voltage 20 - 250 V AC/DC • Relay output, optional time relay (1 sec. - 10 min. adjustable) • Optional on-delay or off-delay switchable • Low power consumption, 2 mA only • Intelligent micro controller technology The 95 series capacitive sensors are favoured in the agriculture industry as a universally applicable device. The reasons, apart from the quality and reliability, are the wide supply voltage range of 20...250 V AC/DC (alternating current and direct current), the easy mounting and installation and the potentialfree relay output. The sensors can be connected to PLC’s or using directly by the consumer for control purposes to a max. 1 A. The Components of the KAS are mounted in plastic or metal casings and encapsulated with epoxy casting resin. Therefore all devices are insensitive to dirt, vibration (vibration stability: 30 g, 100…2000 Hz, 1 hour) and are watertight (depending on the type, up to IP 68). The plastics used for the housings are: • POM (polyoxymethylene) • PA (polyamide) 6.6. Glass-fibre reinforced • PC (polycarbonate) • PPO (polyphenylenoxide) • PTFE (polytetrafluor ethylene) (FDA 21 CFR 177.1550) (For the housing materials used please see the respective technical specifications of the model).

All sensors shown in this brochure are for non-flush mounting. This means they are designed for applications where the active area of the sensor is in contact with the material to be detected. With this kind of level control the sensor head (active area) is completely immersed into the powder, granulate or liquid.
