The MD50 is a cable-mounted admittance switch for top-mounted high-level applications.
Admittance probes utilise similar technology to capacitance to detect product level but feature an additional reference probe.
The probe changes output when the product enters the vicinity of, or makes contact with, the sensor. This operating principle is reliant upon the dielectric properties of the media. The advantage of this technology is that it can work with a considerable build-up on the probe without false switching as it can distinguish between a coating and product level.
Hycontrol supplies the MD series probes with a pre-set material detection sensitivity, which suits most applications. Only when a sticky conductive material is to be detected may increased sensitivity be required. Unlike some competitive products, the transmitter does not require replacement with a more sensitive model should sensitivity adjustment be required. A range selection switch and potentiometer are provided for maximum sensitivity adjustment flexibility. Their low maintenance requirements make them an ideal choice for many applications.
