wenglor Opens New, Automated Calibration Center for Fluid Sensors

At wenglor, 100% quality means that each and every sensor is thoroughly checked for correct functioning before it’s shipped. To make this quality inspection even more efficient for temperature, pressure and flow sensors, wenglor has created a new calibration test bay for series production of the weFlux² product range.

In collaboration with specialists for refrigeration and heating technologies, namely H&H Gerätebau GmbH, the engineers have developed a high-performance system which can simultaneously calibrate up to nine sensors. Extreme temperature ranges in piping systems from 4 to 94° C can thus be realistically simulated with flow rates of up to 200 liters per minute (with an inside pipe diameter of 26 mm), thus making it possible to maximize control precision. With a temperature stability of < 0.1° C, temperature accuracy of ± 0.5° C and flow accuracy of ± 0.2 l/min, the fine measuring probes can be calibrated to the target medium fully automatically.

Project manager Jakob Kraus of H&H Gerätebau GmbH is happy with the strengths which result from this technology partnership: “We’re convinced that we’ve found the ideal solution for precision calibration of the sensors with our know-how in the field of refrigeration technology. Greatest possible precision was very important to us – after all, even minimal temperature deviation, for example, can have serious consequences during later use of a measuring instrument. We’re pleased with our long-term partnership with wenglor in such an innovative field of technology”. And wenglor fluid sales manager Michael Tiffe adds: “With the new test center, we can now secure even more quality for our customers even faster than before, and at the same time schedule even larger quantities – this is extremely important for us!”
