3-A certified, these food-safe switches trigger automated controls and alarms when food-processing, pharmaceutical, and biotech lines reach a set pressure. These switches have many features that make them safe for sanitary environments because they reduce the space where bacteria could grow. A sleeve shields internal parts from water and other contaminants. Polished surfaces and smoothly welded seams make cleaning easier. Made of 316 stainless steel, they stand up to harsh cleaners and sanitizers without rusting. Rated IP67 and NEMA 6, they’re dust tight and withstand washdowns and temporary submersion.

Connect them to your line with the same quick-clamp fittings (also known as tri-clamp fittings) that are common on sanitary lines since they’re easy to take apart for cleaning. The quick-clamp end has a diaphragm that protects the switches from corrosive material and covers threads to keep them clean. The diaphragm is filled with 99.5% pure USP food-grade glycerin, which keeps the switch clean if the diaphragm fails. It’s also laser etched with the serial number to reduce crevices.

Twist the adjustable setpoint ring to make quick changes. These switches are single pole, double throw (SPDT) and can be installed to turn one circuit from off to on (normally open) or from on to off (normally closed).

All have a material certificate with traceable lot number and a calibration certificate traceable to NIST.

When these 3-A certified switches reach a set pressure or vacuum, they trigger controls and alarms in food-processing, pharmaceutical, and biotech lines. They have a sleeve to shield internal parts from water and contaminants. Their surfaces are polished and their seams are continuously welded, so cleaning is easy and there’s little room for bacteria to grow. Made of 316 stainless steel, these switches stand up to harsh cleaners and sanitizers without rusting. Rated IP67 and NEMA 6, they’re dust tight and protected from washdowns and temporary submersion.

Easy to clean and install, these flow switches are 3-A certified to meet sanitary design standards and insert into your line with a quick-clamp mounting adapter (sold separately). They have a smooth probe, and unlike flow switches that measure with a paddle or turbine, these don’t have moving parts for contaminants to get stuck in. Rated IP67 and IP69K, they withstand temporary submersion and high-temperature, high-pressure washdowns. The mounting adapter attaches to a quick-clamp tube tee or outlet (often called tri-clamp fittings) in your large-diameter tubing system using a gasket and clamp (not included), so you don't need to disassemble your line for inline installation. This mounting adapter is also easy to remove and clean.

They send digital signals to your programmable logic controller (PLC) to activate automated controls or alarms when they reach a set flow rate. To calculate the flow rate, they generate a small amount of heat, then measure the cooling effect your liquid or gas has on it. This makes them ideal in applications with fluctuating temperatures. Use the buttons on the display to adjust the set point and other settings. They’re accurate in any mounting position.
