HOMEd5WIKA Pressure Productsd5Ultra high purity transducer WUD-20, 25, 26
The WUD-2x series high-purity sensors combine advanced sensor concepts with analog output signals to provide safe and accurate pressure measurement for current market demand. The pressure measurement based on vacuum benchmark, as well as electronic measures for interference shielding and signal noise elimination, ensure high-precision pressure measurement and excellent long-term stability. The active temperature compensation function reduces the impact of temperature changes on the sensor, ensuring safe operation even in applications with large temperature fluctuations (such as Joule Thomson effect under gas expansion) or in areas without air conditioning. The WUD-25 pipeline and WUD-26 surface mounted sensors are specially designed to withstand the twisting stress caused by installation. The special design of thin film sensors eliminates the risk of sensor failure caused by loads at process connections or welding joints.
