Hygienic ultrasonic sensors

Stainless steel ultrasonic sensors for cleaned environments

In food processing and other cleaned environments, in addition to detection, the shape of the surface, the sensor material and the mounting method are important. The hygienic design makes integration into equipment easier where deposits of dirt need to be limited and the area around the sensing point needs to be cleaned repeatedly.

UMC diffuse sensors and UME ultrasonic through-beam barriers

UMC3000: diffuse version for detection or measurement using the echo from the target. Compare UMC3000-30H-E5-5M-FA with a switching output and UMC3000-30H-I-5M-FA with an analogue current output. The manufacturer's documentation for the series states a range of 200–3000 mm and protection IP68/IP69K.

UME1000: split through-beam barrier with emitter and receiver, for example UME1000-18H-SE2-FB. The range also includes the variants UME1000-18H-SE2-FA and UME1000-18GH-SE2-FB.

What to verify for a hygienic installation

• Cleaning: temperature, pressure, exposure time and chemical composition of cleaning agents.
• Mounting: the prescribed bracket or clamp and the cleanability of the entire connection.
• Measurement: distance, blind zone, target position and output signal.
• Odolnost: the required degree of protection and approval of the specific variant, including the supply cable.

Is a high IP rating alone enough for a hygienic environment?

The IP rating describes protection against ingress of water and dirt under specified conditions. For a hygienic installation, the design, materials, cleaning and mounting accessories are also assessed.

Manufacturer's documentation: UMC3000 series and UME1000 through-beam barriers.

Selection questions

What is the difference between the UMC and UME hygienic series?

UMC uses the reflection of sound from the target. UME is a split through-beam barrier with an emitter and receiver. Therefore start the choice with the sensing task and the available mounting space.

How to choose a switching or analogue version of UMC3000?

UMC3000-30H-E5-5M-FA offers a switching output, the UMC3000-30H-I-5M-FA variant a current analogue output. Compare the required control input, working range and cleaning conditions of the specific version.
