The pms ultrasonic sensors

are designed for the most demanding hygienic requirements according to EHEDG guidelines. Two versions of the sensor are available: D12 adapter shaft and D12 bayonet catch. The standard version D12 adapter shaft is mounted with a hygienic screw connection BF-pms/A1 or an adequate mounting clip.

The innovative design of the stainless steel housing ensures that the pms sensor has no horizontal surfaces in almost all conceivable installation positions. Even with horizontal installation of the hygiene sensor for measuring vertical downwards, the rear side of the housing maintains an angle of ≥ 3°. Cleaning fluids can safely drain off the housing.

The smooth stainless steel housing has a roughness depth of Ra < 0,8 µm and has no crevices and dirt edges. Besides the sensor design, the right material is crucial. The ultrasonic transducer is protected by a PTFE foil and withstands chemically aggressive cleaning agents and disinfectants. The pms has a high endurance and is ECOLAB certified.

Stainless-steel sensor in wash-down design, all horizontal surfaces are at least inclined by 3°

For the pms hygiene sensors

there are 2 output stages and 4 detection ranges available:

1 Push-Pull switching output with pnp or npn switching technology
1 analogue output 4–20 mA or 0–10 V

Sensors with switching output have three operating modes:

  • Single switching point
  • Two-way reflective barrier
  • Window mode

Teach-in of a single switching point

  • Place object to be detected (1) at the desired distance
  • Apply +UB to pin 2 for about 3 seconds
  • Then apply +UB to pin 2 again for about 1 seconds

Teach-in of a switching point

Teach-in of a two-way reflective barrier

with a fixed reflector

  • Apply +UB to pin 2 for about 3 seconds
  • Then apply +UB to pin 2 again for about 10 seconds

Teach-in of a two-way reflective barrier

For setting an analogue output

  • initially position the object to be detected on the sensor-close window limit (1)
  • Apply +UB to pin 2 for about 3 seconds
  • Move the object to the sensor-distant window limit (2)
  • Then apply +UB to pin 2 again for about 1 second

Teach-in of an analogue characteristic or a window with two switching points

To set a window

with two switching points ist in gleicher Weise zu verfahren wie bei einem Schaltpunkt.


and rising/falling analogue characteristic curve can also be set via pin 2.

Versatile applications

Beverage industry

The pms ultrasonic sensor detects glass and PET bottles in operating mode and withstands the cleaning intervals of filling machines. The sensor is mounted with the hygienic sensor mounting BF-pms/A1. For example, pms-25/F ... with push-pull switching output to count bottles.

Within the food industry

containers have to be counted or positioned, volume flow checked on conveyor belts, or food items have to be controlled on filling level and completeness. Two pms ultrasonic sensors monitor the completeness of apples in packaging boxes. For example, 2 x pms-25/F ... each with push-pull switching output for height control.


Within the pharma industry

ampoules and glass vials have to be counted and the volume flow in the filling level process has to be controlled. On a turntable, a pms sensor controls the volume flow of glass vials ahead of the filling line. For example, pms-35/U ... with voltage output 0-10 V.
