The pressure gauges with capsule type element are used for measurement of small negative or positive gauge pressures in gases. Two diaphragm element halves soldered together are part of the capsule element. If pressurized from the inside, the diaphragm element expands by a precise amount. The motion of the pointer comes from the expansion of the diaphragm element.
For the manufacturing of all stainless steel pressure gauges for the chemical industry with capsule type element high quality stainless steel is used. These gauges are therefore suitable for the measurement of aggressive or corrosive gases.
A rear mounting bracket, cover ring, triangular front ring or front mounting flange as required for the installation conditions are available as options.
