1133 Differential Pressure Gauge

Brand: Ashcroft Inc
Does not ship to VA, United States

The Type 1133 differential pressure gauge is an economical means for measuring very low pressure with high static between two independent pressure sources.

It uses a convoluted diaphragm to sense low inches of water differentials while ensuring no migration of the process media.
Features
  • Large convoluted diaphragm actuator 
  • Stainless steel case 
  • Static pressures up to psi 500 (kPa: 3,447, bar: 34.47) 
  • Aluminum (2) and stainless steel bodies (3) 
  • Buna-N diaphragm & O-rings (others available) 
  • Superior magnets for smoother power motion 
  • Standard switches available
