ISO9001 Certified Pressure Gauge with Diaphragm Seal

Pressure gauges with diaphragm seals are designed to isolate the sensitive measuring element from the process media, especially when dealing with corrosive, viscous, or sediment-laden substances. This helps prevent clogging, corrosion, and solidification, ensuring accurate and reliable pressure readings. These gauges are ideal for use in environments where standard pressure gauges may not perform well due to harsh conditions.

Applications:

Used in applications where the media is corrosive and could damage a standard Bourdon tube gauge.

Suitable for high-temperature environments where conventional gauges might fail.

Ideal for highly viscous or crystallizing media that can block pressure ports of gauges, switches, or transmitters.

Commonly used in environmental technology, mechanical engineering, and plant construction industries.

Effective for non-homogeneous media containing suspended solids like wood pulp, which could otherwise clog pressure ports.
