Basic information
- highly viscous liquids
- solid particles, sedimenting sludges
- hot liquids that solidify or crystallize when the temperature drops
- aggressive liquids
- in cases where there are strict requirements for perfect cleaning and sanitation of the system
The given concept consists in the use of a separating membrane and an inert liquid, which transmits the pressure to the measuring device of the pressure gauge (manometer).
Properties of pressure gauges (manometers) with a sanitary diaphragm
- The pressure gauge is made from stainless steel: the housing material AISI 304, the thread material AISI 316. The sensing device is a Bourdon stainless steel spring.
- The connector is TIG welded.
- It is supplied with a glycerine filling as standard (protection against operational shocks).
- Sight glass.
- Bottom connection: CLAMP DIN 32676 – DN40 (50,5 mm)
- Dial: 100 mm
- Measuring range: 0–6 bar
- They meet the requirements of EN 837-1, accuracy class CL 1
- The sanitary diaphragm material: AISI 316L (1.4404)
- The body material of the sanitary diaphragm: AISI 304 (1.4301)
- Working temperature: –45 °C to +150 °C
- Diaphragm designed for pressure range: 0–60 bar
- Filling liquid: food-grade oil
- They are designed with an emphasis on longevity and extreme operating conditions.
- They are designed for the food and beverage industry, and wherever the emphasis is on thorough sanitation and cleaning. Pressure gauges can also be used in operations where vibrations or pulsating pressures occur
