Brief introduction:
Yk-1003 capacitive thin film vacuum gauge is assembled by strict process with internationally advanced sensors and high-precision electronic components. It adopts dry pressure measurement technology without intermediate fluid, gives full play to the technical advantages of the sensor, and has excellent technical performance. It has strong resistance to overload and impact, small temperature drift, high stability and high measurement accuracy.
Main features:
• strong resistance to overload and impact
• high stability: over 0.1% full range per year
• strong anti-interference ability: waterproof, dustproof, shockproof, explosion-proof, anti-corrosion
• wide applicability: the product has a variety of models, a variety of process connection forms, a variety of process connection materials, can be suitable for various occasions in the measurement.
• easy installation: the product has reasonable structure, small volume and light weight, and can be installed directly at any position.
Working principle:
The pressure of the medium under test ACTS directly on the diaphragm of the sensor, causing the diaphragm to produce a small displacement proportional to the pressure of the medium. After the electronic circuit detects this displacement, the displacement is converted into the corresponding standard industrial measurement signal.
In the case of overpressure, the diaphragm is directly attached to the solid substrate. Since the gap between the diaphragm and the substrate is only 0.1 mm, the maximum displacement of the diaphragm can only be 0.1 mm in the case of overload. Therefore, the structure ensures that the diaphragm will not produce excessive deformation and the sensor has a strong impact resistance and overload resistance.
