The SYP series pressure sensor uses metal strain gauges or semiconductor strain gauges attached to a specific surface of an elastic element. When physical quantities such as force, torque, velocity, acceleration, and flow rate act on the elastic element, it will cause changes in the stress and strain of the element, which in turn will cause changes in the resistance of the strain gauge. The change in resistance is processed by a circuit and output as an electrical signal, which is the working principle of a resistance strain sensor, The SYP series pressure sensor uses high-precision pressure sensor components, and the built-in circuit converts the millivolt signal output by the sensor under pressure into a standard current or voltage output signal. The structure adopts a fully stainless steel integrated welding process to ensure that the product can work stably for a long time under harsh working conditions.
The SYP250E series explosion-proof pressure sensor is a product designed specifically for hazardous working conditions where explosions may occur. This product includes two types of explosion-proof: intrinsic safety explosion-proof and explosion-proof, both of which have passed the explosion-proof certification of the National Explosion proof Electrical Product Quality Supervision and Inspection Center.
