wika Differential pressure gauge with capsule element 716.11 736.11
Applications
■■ Differential pressure measurement at measuring points
with very low differential pressures, for gaseous, dry,
clean, oil and grease free media
■■ Model 736.11 also for aggressive media and environment
■■ Filter monitoring in ventilation and heating systems
■■ Filter monitoring in overpressure and clean rooms
■■ Differential pressure controlled monitoring of ventilator
and blast pressures
Special features
■■ Differential pressure measuring ranges from 0 … 2.5 mbar
■■ As a standard zero adjustment in front
■■ Ingress protection IP 66
■■ Case from stainless steel
