ifm, the German automation group, has introduced a new hygienic ultrasonic sensor aimed at tightening precision and compliance in food, pharmaceutical, and water-treatment processing.
The SU Puresonic Hygienic sensor is designed to measure the flow of both conductive and non-conductive liquids, ranging from ultrapure water to cooking oils such as sunflower and rapeseed.
The company said the device’s stainless steel measuring tube, which contains no seals, moving parts, or internal elements, reduces the risk of leaks, blockages, and pressure drops — common causes of downtime in production environments.
The unit’s clamp connection, built to DIN 32676 standards, allows for rapid, tool-free installation and removal. The design also minimises dead spaces, aiding cleaning and sterilisation processes, which are essential in industries governed by strict hygiene requirements.
ifm said the expanded SU Puresonic range covers nominal widths from DN15 to DN100, and operates between -40°C and +120°C, withstanding short-term exposure up to 150°C. Wetted surfaces feature a maximum roughness of 0.4 µm, meeting hygiene demands in regulated sectors.
The company positioned the launch as part of its broader push to offer more robust, maintenance-free measurement technologies for critical production settings.
The family-owned group supplies automation, safety, and sensor systems to industrial customers worldwide.
