• • • Overview of Product • • •
MS324 economical pressure sensor and transducer is a civil and industrial product with large capacity and low costs, which establishes a new standard of performance – cost ratio. This series of product is widely used for pneumatic and hydraulic detection even worst medium environment such as sewage, vapor, slight corrosive liquid and gas.
MS324 series is designed with advanced micro – processed silicon pressure – sensitive resistance metal membrane, adopting micro – melting technology, to solidify the high – temperature glass on the stainless steel isolating glass membrane. Thus, the glass cohesion may avoid influence of temperature, humidity, mechanical fatigue and medium to the adhesive and the material so as to strengthen long – term stability performance of the sensor in industrial environment. Meanwhile, it may also avoid the effect of P – N junction in a traditional micro mechanical sensor.
