Differential Pressure Gauges

1125

The Ashcroft® differential pressure gauge is an economical way to display the difference of two separate inputs on one dial indicator. The case style is similar to other Ashcroft gauges, making panel gauge consistency possible. This product is supplied with bronze Bourdon tube and socket.

1127/1128 Series

When the process is corrosive to gauges with bronze/brass wetted parts an alternative was to isolate the gauge from the process with capillary and isolators or diaphragm seals. Now, when the process is compatible with 316 stainless steel, the user can select Types 1127 or 1128 differential...

1130

The Type 1130 uses a piston design where small migration of the process media is permissible.2 It is recommended for high differential and high static pressures, up to 6000 psi. Body materials are available in Aluminum, Brass and Stainless Steel, with Buna, Viton or EPDM seals.3...

1131

The Type 1131 is utilized for applications where migration of the process media is not permissible. The Type 1131 uses a rolling diaphragm design to separate the high and low-pressure ports to isolate the media and can see up to 3000 psi static pressures. Body materials are available in Aluminum...

1132

The Type 1132 uses a convoluted- diaphragm design with no migration of the process media. It is recommended for lower differential and high static pressures, up to 1500 psi. Body materials are available in Aluminum, Brass and Stainless Steel, with Buna, Viton or EPDM seals.⁽²⁾ 

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,...

1134

The Type 1134 uses a convoluted- diaphragm design with no migration of the process media. It is recommended for low differential inches of water ranges. Body material is glass filled nylon with Buna or silicone.⁽²⁾ 

1200 SERIES

Our piston sensor models are for liquid applications where durability and long life are required. Their simple design has fewer parts to wear out and also keeps the price low.

A magnet attached to the dial pointer shaft follows a spring-loaded sensor magnet that moves as differential...

1500/1800 SERIES

Select these diaphragm sensor models where low differential pressures exist. The popular 1516 model measures from 0-1 psid up to 0-50 psid. Our 1800 series models include our most sensitive diaphragm which can measure from 0-5" H2O to 0-8 psid. We also offer compound range models with...

1502 SERIES

Our 1502 and 1533 models have a heavy-duty diaphragm that is designed for high differential pressures, to 300 psid. This extends the range of our diaphragm sensor DP line – much higher than the more sensitive 1516 model. Though heavy-duty, the diaphragms are still flexible and repeatable enough...
