Description
High-precision multivariable differential pressure sensors that adopt a high-stable silicon core imported by Germany, which is compactly designed, to use 5VDCvoltage input, output is 0~100mV that is proportional to pressure. There is static pressure sensor and temperature sensor in the internal encapsulation that is used for testing and compensating of static pressure and temperature.
The unique overload protection design to make its anti-overload pressure can up to 40Mpa.
Standard full range
»1Kpa, 6Kpa, 40Kpa, 250Kpa, 2Mpa
Features
»Full stainless steel filling silicon to welding and sealing structure
» Case standard thread is M56*1.5, and to change according to customers' requirement.
»The accuracy can up to 0.05% after additional compensation circuit
»Static pressure error can up to 0.05%/10Mpa
» The standard range of static pressure sensor is 40Mpa, can select 3Mpa, 10Mpa
»Touch liquid diaphragm is 316L stainless steel
» Hastelloy or 316 L gold-plating
