PTM90 monocrystalline silicon pressure sensor adopts MEMS monocrystalline silicon pressure chip imported from Germany to achieve international leading overpressure performance and ensure excellent signal stability. It is assembled using a fully welded sealed structure and filled with silicone oil under high vacuum. The material of the measuring diaphragm can isolate the measured medium from the pressure chip, and at the same time enable the sensor to perform long-term and reliable measurement of the differential pressure signals of various strongly corrosive media.
Characteristics:
1,Adopt German imported MEMS monocrystalline silicon pressure chip
2,With overload protection
3,316L stainless steel all-welded integrated structure4,Gauge type can be used for negative pressure measurement5,Suitable for various threaded shells
Use and Industry
• It is easy to install and simple, with high vibration and shock resistance. lt is widely used in process control, aviation, aerospace, automotive, medical equipment, HVAC and other fields
• It is especially suitable for occasions that require high pressure measurement accuracy.
