Stainless steel manometer with a sanitary diaphragm DIN 11851, dial 100 mm | nut DN25 Stainless steel manometer with a sanitary diaphragm, DIN 11851, dial 100 mm | nut DN32 Stainless steel manometer with a sanitary diaphragm, DIN 11851, dial 100 mm | nut DN40

Technical data of a sanitary diaphragm with cap nut:

• The membrane material: AISI 316L (1.4404), Ra≤0,8 µm
• The body separator material: AISI 316 (1.4401)
• The nut material: AISI 304 (1.4301)
• Working temperature: –45 °C to +150 °C
• Diaphragm designed for pressure range: 0–60 bar
• Filling according to application requirements: silicone oil, vegetable oil (almond)
• Manometer connection to the separator: 1/2 "BSP female thread
• Separator connection: food screw connection - union nut DN25 or DN32 according to DIN 11851

Technical data of all-stainless steel manometers, dial 100 mm (4 "):

• The pressure gauge is made of stainless steel, housing material AISI 304, and 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).
• Measuring range: 0–2.5 bar/0–6 bar/0–10 bar.
• Working temperature: -20 °C to +200 °C
• Ambient temperature: -40 °C to 60 °C
• Straight sight glass.
• Bottom connection, thread G1/2" BSP.
• Dial size DN 100 mm.
• They meet the requirements of EN 837-1, accuracy class CL 1.0.
• They are designed with an emphasis on longevity and extreme operating conditions.
• They are also designed for operation where vibrations or pulsating pressures occur.

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

This type of pressure gauge (manometer) 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 given concept consists of the use of a sanitary diaphragm and an inert liquid, which transmits the pressure to the measuring device of the pressure gauge (manometer).
