Kromschroeder DG50UG-4 (84447020) gas pressure switch

Krom schroder DG50UG-4 84447020 gas pressure switch designed for careful monitoring of pressure fluctuations in the gas environment or airspace. The Kromshroeder DG50UG-4 84447020 pressure switch works effectively regardless of the direction of pressure changes, whether it is increasing or decreasing.

Krom schroder DG50UG-4 84447020 pressure switch technical data

Adjusting range: 2,5-50 mbar

Gas type: natural gas, town gas, LPG (gaseous), flue gas, biogas (max. 0.1 %-by-vol. H2S) and air

Switches with rising positive pressure (gas/air), negative pressure (air), differential pressure (air-air)

With gold-plated contacts

Electrical connection via screw terminals and M16 cable gland, IP 65

Maximum medium and ambient temperatures: -20 to +80°C

Long-term use in the upper ambient temperature range accelerates the ageing of the elastomer materials and reduces the service life
