Industrial production sites involve complex conditions, encompassing both routine operating conditions and severe application scenarios such as corrosion, high temperatures, intense vibration, explosion-proof requirements, and sterile environments. Whether a pressure gauge matches the on-site conditions directly affects measurement accuracyand instrument service life.
Backed by a comprehensive pressure gauge product line, BIIC provides full coverage for all types of routine and severe operating conditions, delivering tailored solutions for different site requirements to fully meet the pressure monitoring demands across industries.
01 Routine Operating Conditions | Clean Water, Air, General Oils
Requirements: Steady-state pressure monitoring, high operational stability, compatibility with general pipelines.
Models: Stainless steel pressure gauges, stainless steel capsule pressure gauges, etc.
Suitable for non-corrosive, ambient temperature media in HVAC, water supply, ventilation and negative pressure applications. Available in accuracy classes including Class 1 and 1.6 standard gauges, as well as Class 0.25 and 0.4 precision gauges, with ranges covering from 250 Pa (micro-pressure) to 250 MPa (high pressure). Lower ranges, vacuum/compound combinations, mounting styles, and connection customization are also supported.
