1133 Differential Pressure Gauge
Brand: Ashcroft IncThe 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
