MANODAMP® - Movement with mechanical axle damping

  • long-lasting and reliable
  • for rough industrial environments
  • no oil leakage, no oil refilling
  • no blurry oil colored glasses
MANODAMP®

Rough industrial work environments with vibrations or sudden pressure changes require a special protection mechanism for the Gauge movement with the needle pointer. 

The standard solution of oil filled gauges achieves a damping effect but requires regular refilling maintenance due to the evaporation of the glycerin oil. Oil leakage due to a mechanical gauge damage can cause potential contamination of the process media. Hot and humid climatic conditions have an effect on the oil color and lead to a milky or blurry display glass window. 

Schmierer has developed, field tested and successfully used mechanically damped pressure gauges with a uniquely designed MANODAMP® technology in production plants worldwide over the past years.

Advantages

MANODAMP® Gauges have significant advantages to the “classical” liquid-filled gauge cases:

  • No leakage problems with gauge fillings
  • No risk of contamination of measured media
  • No blurry gauge glass window due to oil colouring after a short time of use
  • Suitable in hot and humid climates
  • Easy maintenance for needle zero readjustment or change of movement parts
  • Long gauge life cycle in rough environment
  • Modern up to date construction fulfills the technical and hygienic requirements of chemical, petrochemical, food and pharmaceutical industries
  • Economic advantage: no oil refilling maintenance required
  • Excellent long term testing results with satisfied customers worldwide

The Working Principle

The MANODAMP® damped pressure gauges retain a smooth pointer movement rough manufacturing environments with vibrations, pulsations, pressure spikes or drops.  This technology operates on a movement of double damped axles (pointer and segment shafts) and a unique construction of the connection to the measuring element with compensating springs. It is used in Schmierer pressure gauges with 100 mm or 160 mm diameter with a pressure above 2.5 bar.
