Drawing on our longstanding experience in the design, and production of metal fiber media filter elements, PTI has led development of improved hydraulic system filter elements for the US Army. Early tests have shown a significant improvement in system cleanliness, on stream life and resistance to cyclic flow contaminant migration.

Aerospace Indicators
7587717 Low Pressure Delta P Indicator with Rolling Diaphragm Image
7587717 Low Pressure Delta P Indicator with Rolling Diaphragm

This rolling diaphragm indicator detects differential pressures as low as 5 psid +/- 0.5 psid up to 15 psid +/- 1.5 psid while maintaining a size compact enough to be mounted in a SAE-AS33514-8 port. High pressure sensing port is located radially on the OD just below the .750-16 UNJF mounting threads with the low pressure sensing port opposite and along the axis of the signal button. Signal: Visual. Reset: Manual.

7593160 Electrical and Visual Delta P Indicator Image
7593160 Electrical and Visual Delta P Indicator

Electrical and visual design couples MIL-S-8805 microswitch to the magnetic pop-out button. The mechanical motion of the pop-out button drives the snap acting SPDT microswitch. The switch can be wired for normally open or normally closed circuits. Hermetically sealed, gold contact switches recommended for all high temperature (to 500ºF) or low load applications (6 Volt, 0.010 amp circuit). Many mounting configurations and electrical connectors are available, or can be built to customer specification. Signal: Electrical and Visual. Reset: Manual (Automatic reset also available).

7593485 Delta P Indicator with Bypass Image
7593485 Delta P Indicator with Bypass

This indicator has a high pressure sensing port located at the bottom of the indicator, opposite and along the axis of the signal button. The low pressure sensing port is located radially. Signal: Visual. Reset: Manual.

7563890 Delta P Indicator with Axial High Pressure Port Image
7563890 Delta P Indicator with Axial High Pressure Port

Compact design provides a visual pop-out button signaling impending bypass. With the application of additional pressure, the indicator cracks to permit bypass. The standard unit designed for use with a 0-12 GPM flow rate, 50 psid +/- 5 psid actuation, 60 psid +/- 10 psid cracks with a 10 psid minimum between actuation and crack. High pressure sensing port is located at the bottom of the indicator, opposite and along the axis of the signal button. The low pressure sensing port and bypass openings are located. Signal and bypass functions are accomplished in a very small, lightweight package. The overall length of the indicator with bypass is 1.800″ with a 0.743″ OD. Signal: Visual. Reset: Manual.
