sanitary Pressure Gauge with Varivent diaphragm (mod. SA 40 Varivent)

The traditional Bourdon spring gauges are not suitable for pressure’ measurement in the food industry. In fact the alimentary fluids could obstruct the sensitive element (Bourdon spring) while entering and deposit themselves on the inside, with subsequent hygienic problems due to the bacterial contamination.

To avoid the above-mentioned problems the gauge must be supplied with a diaphragm seal made of an appropriately shaped diaphragm made of AISI 316 stainless steel. As the gauge and the diaphragm are connected in a whole body, their assembly and disassembly causes no problems. The diaphragm seal has a threaded connector according to the DN-SMS-IDF-CLAMP standards.

It’s fitting to underline that all the SABA pressure gauges with diaphragm seals are damped, so that they can work correctly even in presence of strong pulsations.
