KROMSCHRODER - 84447350 GAS PRESSURE SWITCH, DG50U-3, 50MBAR POSITIVE PRESSURE, NEGATIVE PRESSURE, DIFFERENTIAL PRESSURE (84447350/84447352)

Gas Pressure Switch, DG50U-3

The DG50U-3 gas pressure switch has been designed to monitor extremely low-pressure differentials and trigger a switch-on, switch-off or switch-over operation if a set switching point is reached. The switching point is adjustable via a built-in hand wheel and is field proven in the monitoring of positive and negative gas pressures of various industrial gas and air appliances.

For when reliability matters, this gas pressure switch is suitable for monitoring positive pressure: Gas, air, flue gas or biomethane and negative pressure Air or flue gas. Suitable for multiple applications including gas deficiency monitoring of inlet pressure, system leak tightness checks for shut off valves, differential pressure monitoring of air filtering systems and boiler fan monitoring and differential pressure monitoring in firing, ventilation and air-conditioning systems.

DG50U-3 Gas Pressure Switch Features:

• Adjusting range 2.5 - 50 mBar
• Mean switching differential at min/max setting 0.8 - 1.5 mBar
• Deviation from switching point +/- 15%
• Monitoring of gas and air pressures (positive, negative and differential pressures)
• Certified for systems up to SIL 3 and PL e
• Pressure switch with internal lock and manual reset
• Suitable for biologically produced methane (can be used on pipes with Zone 2 explosive atmospheres without isolating amplifier)
• With approved isolating amplifier for Zone 1 and 2 hazardous areas
• EU certified pursuant to EN 1854 and class 'S'
• RoHS 2002/95/EC and follow-up directive 2011/65/EC
