614.11 Capsule pressure gauge with WIKA copper alloy pressure element

Description

614.11 Capsule pressure gauge with copper alloy pressure element WIKA is used in the measurement of differential pressure of gaseous and liquid media.

The capsule pressure gauges models 614.11 and 634.11 are 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.
