This type of pressure gauges (manometers) is used to measure the pressure of liquids and gases in cases where it is inadmissible for the measured medium to enter the measuring device of the pressure gauge.

• highly viscous liquids
• liquids with solid particles, sedimenting sludge
• 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).

• The pressure gauge is made of stainless steel, housing material AISI 304, thread material AISI 316. The sensing device is Bourdon stainless steel spring.
• The connector is TIG welded.
• It is supplied with a glycerine filling as standard (protection against operational shocks).
• Glass sight glass.
• Bottom connection: DIN clamp DN 40 (collar 50.5 mm)
• Size of dials: DN100
• Measuring range: 0–4 bar
• They meet the requirements of EN 837-1, accuracy class CL 1.0.
• Separation membrane material: AISI 316L (1.4404)
• CLAMP separator body material: AISI 304 (1.4301)
• Working temperature: –45° C to +150° C
• Diaphragm designed for pressure range: 0–60 bar
• Filling liquid: according to customer requirements for application
• 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.

The connection is made using a clamp sleeve and a silicone seal with a given clamp counterpart.
