The KPM series is the most common due to its high reliability. Ideal for clean water, but also suitable for a wide variety of media. The KPM opens or closes the electrical circuit at an angle of ±45°. Therefore, the fluid level at which the switch operates is defined by the cable length after the counterweight.
The MPM series has a double liquid-proof chamber giving the switch high reliability and protection on the inside, while still being small (micro). Its shape and large size make it suitable for sewage water application, but it does require a counterweight. The MPM opens or closes the electrical circuit at an angle of ±45°. Therefore, the fluid level that the switch operates is defined by the cable length after the counterweight.
The JPM series type is a tilt level switch that consists of a heavy body, is free of irregularity, doesn’t require an external counterweight, and rotates around itself when submerged. These features make it suitable for turbulent water and industrial wastewater. Typically used in pairs to enable 2 functions (emptying and filling). The JPM series can either enable a normally open (NO) or normally closed (NC) function.
