Kromschroeder DG150UG-4 (84447030) gas pressure switch

Kromschroder DG150UG-4 84447030 differential pressure switch designed to monitor pressure changes in gases or air, regardless of whether it is increasing or decreasing. Kromschroeder DG150UG-4 84447030 gas pressure switches respond to any pressure deviations from the setpoint. When the set pressure is reached, a microswitch with a switching contact is switched on. The trigger level is adjusted using a handwheel.

Krom schroder DG150UG-4 84447030 pressure switch technical data

Adjusting range: 30-150 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

Kromschroder 84447030 DG150UG-4 gas pressure switch maintenance

To ensure reliable operation of the pressure switch, Krom schroder DG150UG-4 84447030 is recommended to conduct an annual leakproofness and functionality check of the device. If Kromschroder 84447030 DG150UG-4 gas pressure switch is used with biogas, this period should be reduced to six months. It is also important to regularly check the functionality of Kromschroeder DG150UG-4 84447030 differential pressure switch, for example, using the PIA check valve, performing pressure reduction monitoring. After carrying out maintenance, it is necessary to check the device for leaks.
