S-P Flanged seals with flush diaphragm

Features

The Aplisens S-P transmits the process pressure signal to the connected pressure transmitter or pressure gauge through a manometric liquid filling the space between the separating diaphragm and the measuring device. The flush diaphragm construction eliminates any dead volume at the process connection, making it particularly well suited for viscous, crystallizing, or contaminated media where a recessed diaphragm would trap process material.

The S-P is available in both direct mount and remote mount capillary configurations. In the direct mount version, the capillary outlet from the flange is axial as standard. In the remote mount version, the capillary outlet is radial as standard, with axial configuration available on request. The maximum capillary length for DN50 / 2" is 10 meters.

Three manometric liquid options cover the full range of operating temperatures. The DH fluid handles very high temperature applications from 15°C to 380°C in direct mount and up to 250°C in remote mount for overpressure measurements. The DC fluid covers high temperature applications from -30°C to +150°C in direct mount and -10°C to +315°C in remote mount. The AK low temperature fluid covers applications down to -60°C for overpressure measurement. When operating at ambient temperatures below 0°C, heating of capillaries filled with DC or DH fluid is recommended.

The diaphragm and flange are manufactured from 316L stainless steel as standard. Special versions are available including other DIN and ANSI standards, food-grade edible oil filling for medium temperatures from -10°C to +150°C, and direct diaphragm seal for medium temperatures above 150°C. The S-P is fully compatible with Aplisens smart and analog pressure transmitters, differential pressure transmitters, and pressure gauges of 63 mm and 100 mm diameter.
