SIEMENS Differential pressure switch QBM81-50 range 1000 to 5000 Pa

SIEMENS Differential pressure switch QBM81-50 range 1000 to 5000 Pa

SIEMENS Differential pressure switch QBM81-50 range 1000 to 5000 Pa The pressure difference between the two pressure take-offs causes the deflection of the diaphragm connected to the spring. This special membrane ensures the long-term stability of the switching points.

Each type of device has a scale for very precise setting of the switching point. The setting options are shown in the 5 diagrams in the "Functions" section.

Differential pressure switches for air and non-corrosive gases, potential-free changeover contact AC 250 V, 5 (3) A. For ventilation and air conditioning equipment For monitoring air filters, air flow, fan operation For pressure monitoring in clean rooms, kitchens, etc.
