Liquid-filled pressure gauge 113.53 in a stainless steel housing, dia 100 mm, -1+5 bar, M20 x 1.5 7479411

Professional glycerin-filled pressure gauge for demanding industrial applications

The 113.53 model pressure gauge from the WIKA series is a measuring device compliant with the European standard EN 837-1. Thanks to the glycerin filling and stainless steel housing, the mechanism remains stable during operation.

Construction and materials for durability in harsh conditions

The stainless steel housing guarantees resistance to corrosion and aggressive industrial environments. The copper alloy-based mechanism ensures precise and stable pressure measurement. The glycerin filling dampens vibrations and oscillations, which translates to readable readings even under heavy dynamic loads.

The polycarbonate window is resistant to mechanical impact and UV radiation. The rolled stainless steel cover further strengthens the device's construction. The IP65 protection rating protects against dust and water jets, allowing installation even in difficult environmental conditions.

Operating parameters and media compatibility

The device measures pressure in the range from -1 to +5 bar, allowing for the monitoring of both vacuum and positive pressure. The M20x1,5 process connection enables standard threaded mounting for hydraulic and pneumatic installations. The bottom connection position facilitates installation and prevents the accumulation of air bubbles.

The 1.6% accuracy class ensures precise reading of process parameters for most industrial applications. The scale resolution is 0.05 bar, and the entire scale contains 32 graduations, enabling accurate reading even of small pressure changes.

The device is intended for measuring chemically inert liquids and gases that do not react with copper alloys - it is ideal for measuring air, water, and other standard hydraulic media.

Industrial applications and operational advantages

The pressure gauge finds particular use in hydraulic systems and condensation installations where high dynamic loads or intense mechanical vibrations occur. It works perfectly as a component for monitoring the operating parameters of hydraulic pumps, actuators, and other devices generating pressure pulsations.

The glycerin filling eliminates the "needle jitter" problem characteristic of standard pressure gauges mounted on machines with variable operating characteristics. This allows the operator to easily read the current pressure value even during the startup or braking of a hydraulic system.

The device meets the requirements of the EN 837-1 standard, confirming its compliance with European quality standards for industrial pressure gauges. A maximum medium temperature of 60°C allows for a wide range of technological applications without the risk of damaging the internal mechanism or degrading the damping fluid.
