Prisma Instruments Diaphragm Sensing Pressure Gauge DSPG are generally used for low pressure where Bourdon is insensitive. The sensing element is diaphragm which is connected to movement assembly through a "ball & socket" arrangement. Pressure is transmitted through the diaphragm to transmission shaft.

Irrecoverable accuracy loss is due to too many mechanichal linkages thereby leading to a standard accuracy of ± 2% FSD (± 1,6% FSD on request). Coincidently construction isolates the process as well. Screwed or flanged process connection can be offered. Lower span of 250mm WC is possible.
