FU4LK suitable for general applications in

  • Food and beverage industry
  • Pharmaceutical industry
  • Biotechnology
  • Sterile process engineering

The device is an electronic flow resp. temperature switch for monitoring, control and continuous measurement of flow and temperatures in liquids.

A high variety of versions of process connections and electronic types allows the use for a wide range of applications, also for demanding measuring requirements.

The process connection of the FU4LK with metallic sealing has been specifically designed for the hygienic, dead-space and elastomer-free process adaption.

Due to its high accuracy and the digital adjustability by RS485 Modbus®-RTU or IO-Link® the device can be suited to a wide variety of applications.

The robust design and the high-quality workmanship turns the device into a very high quality product, which even the most adverse environmental conditions cannot affect, whether the lowest temperatures when used outdoors, extreme shock and vibration stress or aggressive media.

A captive laser marking of the type label ensures the identifiability throughout the entire lifetime of the device.

Obviously is the optional marking of a measurement point designation resp. TAG, a customer label or of a neutral type label, of course also per laser marking.

A LABS- resp. silicone-free version, a factory calibration with calibration certificate and a customer specific configuration resp. preset is also optionally available like a material test certificate EN10204 3.1 or a factory certifications for drink water resp. food suitability.

Customer specific special versions can be realized short-term on request, e.g. special designs for the process connection or other process materials.
