Ashcroft 1130 series differential pressure gauges feature four models offering different pressure ranges and maximum static pressures. Each Ashcroft 1130 series differential pressure gauge is solidly constructed with a stainless steel case and a choice of aluminum, brass, or stainless steel body materials. These analog gauges are available with dials ranging from 2 to 6 inch in size. Connections can be 1/8 or 1/4 inch NPTF and connections can be located inline, on the back, or on the bottom of the gauge. Explosion-proof models are available.
Ashcroft Type 1130
The Ashcroft Type 1130 differential pressure gauge uses a piston actuated design where small migration of the process media is permissible. Available in pressure ranges from 0-5 psid to 0-150 psid (or equivalent), the Ashcroft Type 1130 differential pressure gauge is recommended for high differential and high static pressures up to 6000 psi.
Ashcroft Type 1131
The Ashcroft Type 1131 differential pressure gauge is utilized for applications where migration of the process media is not permissible. The Type 1131 uses a rolling diaphragm actuator design to separate the high and low-pressure ports to isolate the media. Featuring the ability to withstand static pressures up to 3,000 psi, the Ashcroft Type 1131 differential pressure gauge is available in pressure ranges from 0-5 psid to 0-100 psid (or equivalent).
Ashcroft Type 1132
The Ashcroft Type 1132 differential pressure gauge uses a convoluted diaphragm design with no migration of the process media. Recommended for lower differential and high static pressures (up to 1500 psi), the Ashcroft Type 1132 differential pressure gauge is available in ranges from 0-1 to 0-60 psid (or equivalent).
Ashcroft Type 1133
The Ashcroft Type 1133 differential pressure gauge uses a convoluted diaphragm to sense low inches of water differentials while ensuring no migration of the process media. Maximum static pressure is 500 psi, and available with pressure ranges 0-1 to 0-25 inH2O.
