Photoelectric Sensors for Hygienic and Washdown Environments
The QM26 and the QMH26 are designed for the food and beverage and pharmaceutical industries.
The sensors' design considers Hazard Analysis and Critical Control Point (HACCP) principles for hygienic manufacturing processes in areas where they come in contact with food or materials, which makes them suitable for harsh washdown environments with high pressure, extreme temperatures and chemicals. The QM26 is housed in a non-toxic 316L stainless steel housing, and can survive high pressure washdowns and temperature cycling, ranging from -30 to 60 °C. The sensor is ECOLAB certified for inexhaustible sensor life in chemically cleaned environments and is intended for splash zone areas. It also features easy side-mounting for quick set-up and installation. The QMH26 has all the same advantages but is designed with minimal grooves and crevices, leaving no room for bacteria to hide and multiply. It is self-draining for clean-in-place (CIP) applications. The sensor's hygienic mounting shape reduces contamination risk, making it a suitable sensor to place in contact zones.
