Compact Engineering Inc. designs OEM flow switches, OEM level switches, and OEM temperature switches. The flow switches are used for water, air, and electronics applications, and are available as angle body, wire receptacle, low flow, straight body, and indicator types. The temperature switches can serve as low temperature switches or high temperature switches in six narrow differential, preset set points.

Fluid Components International manufactures OEM flow switches and OEM level switches. The flow switches feature stainless steel construction and an industrial design with no moving parts and negligible pressure drop. They are used in liquids, gases and slurries; and suited for low flow pump protection, monitoring lube oil, detecting seal leakage, verifying analyzer flow, and monitoring cooling water. The level switches are used to provide point detection in liquid/gas, liquid/liquid, liquid/foam, and foam/gas interface applications.

Magnetrol International's OEM ultrasonic level switches are designed for the petroleum refining and pulp and paper mill industries. The integrally-mounted switches measure levels within 0.25" from the end of the tip-sensitive transducer, and offer either a 10-amp DPDT gold flash relay or a 5-amp DPDT hermetically sealed relay.

Designed for OEM applications, Innovative Solutions LLC's sub-compact switches can withstand pressures up to 150 psig, and are available with 1/8" NPT or 3/8-16 thread mounting options. UL- approved, the solid polypropylene type switches can handle a range of liquids.
