| The WU-2x series combines advanced digital sensor concepts with analog like output signals to provide safe and accurate pressure measurements that meet the demands of today's market. 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. WU-25 (pipeline type) and WU-26 (surface mounted type) sensors are specifically designed to withstand the torsional stress that often occurs during installation. The special design of thin film sensors eliminates the risk of sensor failure caused by loads at process connections or welding joints. |
