Beryllium copper diaphragm
Wetted materials of beryllium copper, brass, polysulfone and RTV silicone.
The Ashcroft Type 1490 low pressure diaphragm gauge is designed to measure pressure from 10 in.H2O to 15 psi, both positive and negative pressures. This pressure gauge uses a very sensitive diaphragm capsule to measure low pressure and vacuum. The low pressure diaphragm gauge is specifically designed for use whenever the pressure medium is a gas that is not corrosive to beryllium copper, brass, polysulfone and RTV silicone. Typical applications are, but not limited to, vacuum pumps, gas leak detectors, air compressors, air filters, gas burners, gas measurement, vacuum ovens, suction regulators and respirators.
