WNK85MA is a series of high performance compact pressure transmitter by using ASIC signal conditioning chip and dry ceramic capacitive pressure sensor. It has features of anti-corrosion, anti-wear, shock resistance and vibration resistance. Its anti-overload capacity is over 3-5 times of the range, completely solved poor overload in small range of other sensors. In addition to general ranges of normal sensors, its most outstanding characteristic is the positive and negative gauge pressure function. As high output and wide range of its core ceramic capacitive sensor, WNK85MA is especially suitable for harsh industrial environment pressure measurement.

The WNK85 is a high-performance compact pressure transducer engineered for precise pressure measurement in demanding environments, with a primary focus on HVAC systems. It integrates an ASIC signal conditioning chip and a dry ceramic capacitive pressure sensor, forming a core structure that delivers reliability and accuracy across diverse applications.
What sets the WNK85 apart is its ability to excel in harsh industrial settings, thanks to a combination of robust design and advanced technology. Beyond standard pressure measurement capabilities, it addresses critical pain points such as poor overload resistance in small-range sensors, making it a versatile solution for both general and specialized pressure monitoring needs. Whether used with liquids, gases, or steam, this transducer ensures consistent performance, making it a trusted choice for professionals seeking precision in pressure data.
The WNK85 is built to withstand tough conditions, boasting anti-corrosion, anti-wear, shock resistance, and vibration resistance properties. These features ensure longevity even in environments where exposure to harsh media or mechanical stress is common, reducing maintenance needs and extending service life.
A standout feature is its anti-overload capacity of 3-5 times the measuring range, a significant improvement over many conventional sensors that struggle with overload in small ranges. This makes the WNK85 highly reliable in scenarios where pressure spikes are possible, preventing damage and ensuring continuous operation.
In addition to covering standard pressure ranges, the WNK85 offers a unique positive and negative gauge pressure function, expanding its applicability to systems where pressure fluctuations above and below atmospheric pressure need monitoring. Its pressure range is 2MPa-6MPa, with gauge pressure as the primary measurement type, catering to mid-range pressure requirements in HVAC and industrial setups.
