Product Overview
The YNB Series Stainless Steel Liquid Filled Pressure Gauge is designed for low-pressure measurement in industrial systems where mechanical vibration and pressure pulsation may affect reading stability.
The gauge features a stainless steel case and process connection, with glycerin or silicone oil filling available. The filling liquid helps damp pointer movement and improves dial readability under vibrating operating conditions.
With a measuring range of 0–100 kPa and an accuracy class of 1.6, this model is suitable for low-pressure monitoring in industrial equipment, pneumatic systems, water treatment facilities, pumps, and other compatible process applications.
Applications
The YNB Series liquid filled pressure gauge can be used in compatible low-pressure measurement applications, including:
Pneumatic equipment and air systems
Water treatment equipment
Industrial pumps and compressors
Chemical processing equipment
Industrial machinery
Boiler and process equipment
Systems exposed to mechanical vibration or pressure pulsation
Key Features and Benefits
Low-Pressure Measurement: Designed for pressure measurement up to 100 kPa.
Liquid-Filled Design: Glycerin or silicone oil filling helps reduce pointer fluctuation.
