Gems Sensors’ new 1700/1701 range of integral diaphragm sensor features an integral diaphragm made of AISI 316 stainless steel, providing a sensor with sanitary fittings that can be used in sterile environments over wider temperature and pressure ranges than existing devices. Sanitary fittings are required for many food, dairy, brewery, pharmaceutical and chemical industry applications where sterile environments need to be maintained. They are generally produced in corrosion-resistant material to avoid pitting of the surface, which would allow microbes to settle. Previous sanitary fittings have been produced by fitting an oil-filled stainless-steel diaphragm to a standard sensor or transmitter. However, this limits the temperature and pressure ranges at which the sensors can operate, and increases the cost of manufacture. The 1700/1701 transmitters overcome these problems by having a 316 stainless steel diaphragm as an integral part of the unit.
