632.51 Pressure gauge with capsule with stainless steel pressure element WIKA

Description

632.51 Capsule pressure gauge with stainless steel pressure element WIKA is used for measuring pressure differentials of gaseous and liquid media.

The capsule pressure gauge model 632.51 is based on a proven capsule measurement system. The capsule measurement principle is particularly suitable for low pressures. At pressure, the expansion of the capsule element, proportional to the incident pressure, is transferred to the stroke and displayed.

The modular design allows many combinations of housing materials, process connections, nominal sizes and scale. This wide variation in design and connection to the rear bracket makes the instrument suitable for mounting on panels in a wide range of applications.
