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.

The use of these manometers is common in the following cases:

• 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 of stainless steel, housing material AISI 304, thread material AISI 316. The sensing device is a Bourdon stainless steel tube.
• The connector is TIG welded.
• It is supplied with a glycerine filling as standard (protection against operational shocks).
• Straight sight glass.
• Bottom connection: DIN clamp - DN40 (CLAMP collar 50.5 mm), DN50 (CLAMP collar 64 mm)
• Dial size: 63 mm, 100 mm.
• They meet the requirements of EN 837-1, accuracy class CL 1.6.
• 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 fluid: with regard to application and customer requirements (almond oil, silicone 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.

Installation of an all-stainless steel pressure gauge (manometer) with a sanitary diaphragm:

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

Application fields:

Engineering, refrigeration, air conditioning, brewing, food and beverage industry, viticulture, refrigeration, water management applications, chemical industry, etc.
