Product description

The PT219 series pressure sensor adopts high-precision pressure core and precision compensation technology for wide-range temperature compensation. The pressure-sensitive diaphragm adopts a solid diaphragm with a special treatment. The superb mechanical transmission structure design ensures that the hard sand in the measured medium will not Damaged isolation flat diaphragm, compact structure, corrosion resistance, vibration resistance, and impact resistance of hard sand particles. Mainly used in various engineering equipment, tunnel shield machinery, brick making machinery, liquid pressure, oil exploration and mud measurement of water conservancy river dams.
