مفتاح ضغط الغاز من شركة Kromschroeder DG10U-3 (84447300)
Kromschroder DG10U-3 84447300 differential pressure switch designed to monitor pressure changes in gases or air, regardless of whether it is increasing or decreasing. Kromschroeder DG10U-3 84447300 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 DG10U-3 84447300 pressure switch technical data Adjusting range: 1-10 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) Electrical connection via screw terminals and M16 cable gland, IP 54 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 Storage temperature: -20 to +40°C Diaphragm pressure switch, silicone-free Diaphragm: NBR. Housing: glass fibre reinforced PBT plastic with low gas release Lower housing section: AlSi 12 Enclosure: IP 54 or IP 65 Safety class: 1 Line diameter: 0.5 to 1.8 mm (AWG 24 to AWG 13) Line entrance: M16 x 1.5, clamping range: diameters of 4 to 10 mm Electrical connection type: screw terminals Weight: 0,321 kg Kromschroder 84447300 DG10U-3 gas pressure switch maintenance To ensure reliable operation of the pressure switch, Krom schroder DG10U-3 84447300 is recommended to conduct an annual leakproofness and functionality check of the device. If Kromschroder 84447300 DG10U-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 DG10U-3 84447300 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.
