Applications
Section titled “Applications”- Low positive pressure measurement.
- Negative pressure measurement.
- Fluid media with certain corrosivity.
- Non-solidifying and non-crystallizing media.
- Applications requiring diaphragm material selection according to medium corrosion.
Product Features
Section titled “Product Features”- Diaphragm sensing structure for low-pressure measurement.
- Sealed anti-splash structure to protect internal parts from environmental influence and contamination.
- Diaphragm materials include 316, 316L, H.C alloy, Ta, PFA and PTFE.
- Connection material includes 304, 316 and PTFE-sprayed options.
- IP55, IP65 and IP66 protection ratings are available.
Product Principle
Section titled “Product Principle”Under the action of the pressure of the measured medium, the diaphragm produces elastic deformation and displacement proportional to pressure. The transmission mechanism amplifies the displacement through a connecting rod, and the indicating device displays the measured pressure.
