Safety is always a critical consideration in industrial processes, especially in high pressure applications such as pumps & compressors, high pressure processing, test equipment & systems and waterjet cutting. Pressure gauges used in these types of applications must be engineered with exceptional durability to handle heavy stress. Historically, the only standard that addressed mechanical measuring instruments was EN 837-1, which was only applicable for pressures ≤ 23,000 psi.

Established in 2017, DIN 16001 was the first standard to specify safety certification parameters to high pressure gauges, guaranteeing that no harm would be caused by the instrument even in critical applications. DIN 16001 applies to pressure gauges with ranges from >23,000 psi through 145,000 psi (nominal sizes 100 and 160). It defines specific test procedures for the implementation of production type and routine testing. 

All gauges which are constructed in accordance with DIN 16001 must also meet the requirements of safety category “S3”, which necessitates a laminated safety glass lens, a case with a solid front wall between the measuring system and the dial, and a blowout back. In the event of a failure, these features protect the operating personnel in front of the instrument, as the design allows media and gauge components to be ejected through the back of the case.

DIN 16001 also mandates that the continuous pressure limitation of the gauge is at 75% of full scale. The instrument should withstand pressure to complete full scale value for short durations, but should not be exposed to any pressure exceeding full scale.

Backed by our extended warranty, NOSHOK 402/502 Series corrosion-resistant dry or liquid-filled Extreme High Pressure Gauges are in compliance with the DIN 16001 standard.

These gauges exceeded the minimum requirements of the specification by more than 20 times in our qualification cycle testing. Ideal for applications including pumps & compressors, high pressure processing, test equipment & systems and waterjet cutting.

Features include:

• 4” and 6” gauge sizes
• Solid front design with a blow-out back in accordance to EN837, S3 Safety Pattern
• Safety glass lens
• Ranges from 0 psi to 30,000 psi through 0 psi to 85,000 psi
• Most ranges available from stock for quick delivery

Benefits include:

• Improved load cycle stability
• Improved calibration stability
• Significantly longer service life
• Reduced down time

These features combine to provide higher safety levels, improved reliability and reduced maintenance costs, resulting in a lower total cost of ownership.
