Sensors for the dairy industry

Highest quality in dairy processing with precise measurement technology

Dairy production is a business with tight margins and high quality requirements. Milk processing can be optimized to control costs while maintaining product quality at a consistently high level. Thermal milk processing, in particular, is of paramount importance to consumer safety and plant efficiency. Accurate, innovative measurement technology sensors ensure thermal processing in the correct temperature range and compliance with strict rules.


Endress+Hauser understands the high demands and challenges in dairy processing. We offer a complete portfolio of hygienic flow, level, temperature, pressure and analytical sensors designed, manufactured and optimized for the food and beverage industry. Our common goal: ensure product safety and customer health.

  • Precise, robust and reliable measurement technology optimized for industry requirements.

  • Easy to clean and absolutely tight sensors. Ingress protection class up to IP69K availalable to withstands high pressure and steam cleaning.

  • Hygienic sensors meet 3-A sanitary standards and are certified according to test procedure of EHEDG.

  • Food contact material compliant to FDA "GRAS", EC 1935/2004 and China GB4806.

  • Seamless integration into any control system.


Fast temperature sensors improve heating control

The critical control point for successful pasteurization control is temperature. Accuracy and response time ensure that no energy is wasted and the product is not exposed to more thermal stress than necessary.

Temperature sensors in a heat exchanger

Endress+Hauser has invented the fastest temperature sensor for hygienic processes. This innovative technology helps you to improve quality and reduce cost. Furthermore, the combination of precise, fast and stable temperature measurement delivers the highest degree of process quality and reliable product quality.

  • Install our innovative temperature sensor iTHERM TM411 to improve your temperature monitoring in UHT processing.

  • Benefit from the shortest response times (t90 = 0.75 s) in the market thanks to iTHERM QuickSens technology.

  • Take advantage from significant time savings during recalibration (up to 20 minutes per measuring point) with iTHERM QuickNeck.

  • Reduce risk and improve process safety in critical applications with the help of our self-calibrating temperature sensor iTHERM TrustSens.

Flow measurement in milk pasteurization

Accurate flowmeters ensure the right amount of heat is applied to achieve safe results.

Promag H in a dairy plant

Electromagnetic flowmeters carry the main burden of flow measurement in dairy operations and play a critical role in milk heating.

  • Benefit from integrated temperature and conductivity measurement of Proline Promag H.

  • Heartbeat Technology combines diagnostic, verification and monitoring functions for process optimizations.

Reliable level sensors

One of the more challenging applications in thermal processing systems is the level control of the balance tank. The small tank sees rapid level and temperature changes.

Milk storage tanks in dairy production

Hydrostatic level sensor are ideal for this application. Temperature compensated and with ranges down to 100mm H2O, they set the standard for reliability.

  • Use Deltapilot FMB50 with remote electronics. It also help you to reduce risk in the often harsh environment and cleaning cycles.

  • Alternatively, the compact point level switch Liquiphant FTL33 for hygienic applications can be used.

Differential pressure measurement across heat exchanger

To ensure food safety, the differential pressure across the regeneration stage must be maintained. Stability and trust in measurement is key.

Heat exchange in dairy production

For this critical application, an electronic differential pressure measurement is recommended.

  • Optimize your measurement using our innovative electronic dp Deltabar FMD72.

Buildup monitoring to optimize product quality

The microbiological stability of dairy products is crucial for their shelf life and quality, which is often regulated by law. However, heating milk also leads to contamination on the inner walls. This contamination affects the efficiency of the heating cycle and is a potential cause of product contamination. Therefore, controlling the fouling behavior throughout the heating process and the presence of product in the holding tube is key to process control and optimization of product quality.

Liquitrend QMW43 buildup sensor

Our compact multiparameter instrument Liquitrend QMW43 is able to measure the buildup thickness and conductivity of media simultaneously. Installed in the holding tube of the pasteurization process, it can continuously monitor the formation and degree of buildup. This helps to decide if a cleaning process is necessary or if the production time can still be extended without affecting the product quality.

Keep your instrument in spec

Regular calibration ensures that the measuring instruments controlling critical processes remain in spec, which is essential to safeguard food safety and quality.

Calibration experts at work in a dairy

From on-site to fully accredited laboratory calibration, Endress+Hauser provides timely, traceable, and cost-effective calibration services to ensure both high plant availability and compliance of your instruments. Our calibration experts will support you in optimizing all activities across your installed base.
