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: -1 / 1.5 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

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).

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.
