Differential Pressure Gauge, Diaphragm Operated
1133
The Type 1133 uses a convoluted- diaphragm to sense low inches of water differentials while ensuring no migration of the process media. Maximum static pressures for ranges of 5 IWD and below is 45 psi and 500 psi for all other ranges. Body materials are only available in Aluminum, with Buna, Viton or EPDM seals.⁽²⁾
• Large convoluted diaphragm actuator
• Stainless steel case
• Ranges from 1 IWD-25 IWD
• Static pressures up to 500 psi
• Aluminum⁽³⁾, stainless steel bodies⁽³⁾
• Buna-N seals (others available)
• Superior magnets for smoother power motion
• Standard switches available
• 5-year warranty
