Kromschroder DG500U-3 84447550 differential pressure switch designed to monitor pressure changes in gases or air, regardless of whether it is increasing or decreasing. Kromschroeder DG500U-3 84447550 gas pressure sensors 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 DG500U-3 84447550 pressure switch technical data
Adjusting range: 100-500 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)

Kromschroder 84447550 DG500U-3 gas pressure switch maintenance
To ensure reliable operation of the pressure switch, Krom schroder DG500U-3 84447550 is recommended to conduct an annual leakproofness and functionality check of the device. If Kromschroder 84447550 DG500U-3 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 DG500U-3 84447550 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.
