Differential pressure gauge PR 20

dialvertical-mountNPT 1/4

In the Flameproof Model PR 20, the movement of the diaphragm, and hence the movement of the piston magnet is converted into appropriate calibrated rotary movement of the pointer through a magnetic connection. This type of diaphragm model is used in applications where no migration of the media from high pressure side (HP) to low pressure side (LP) is permitted. Specifications Migration - Minor from high to low port First marking on scale - 20% of the FSD Wetted Parts - Body material, SS 302 spring, ceramic magnet & seals Mounting - Direct or 2” horizontal / vertical pipe mounting bracket Body material - SS316 attached to flameproof aluminum enclosure Seals - Buna-N, Viton & EPDM ‘O’ Rings Window - Standard: Float glass Optional: Toughened glass, acrylic & safety glass Over range protection - Up to the max. working pressure from high & low side Weight - Approximately 2.5kg
