DESCRIPTION AND APPLICATION

Optical liquid level sensors are intended for measurement, regulation and control of production in foodstuff (e.g. beverages production) or pharmaceutical industry. They are used also in applications of sensing of a tank filling or emptying, min. and max. liquid level detection, a pump dry run protection etc.

Accessories

metal nut OPT for optical sensor tip

Variants of optical liquid level sensors:

Type ,,A" - suitable for oil liquids (e.g. coling emulsions, oil, crude, hydraulic oil, milk, etc.)
Type ,,B" - suitable for liquids with foam (e.g. beer, ,,cola" type drinks) and other liquids (e.g. water)
