MIL-DTL-9395/32D
REQUIREMENTS:
Dimensions, weight, and electrical schematic: See figure 1.
Calibration: See tables I, II, III, and IV.
Proof pressure: 250 lbf/in2g high over low and simultaneously.
System pressure: 125 lbf/in2g high over low and simultaneously.
Burst pressure: 500 lbf/in2g high over low and simultaneously.
Electrical ratings: Operating voltage: 28 Vdc. Current rating: 4 amperes resistive, 2 amperes inductive.
Seal:
High pressure chamber: Media proof. During this test the low pressure chamber shall be open
to atmosphere. Subject switches to proof pressure for 2 minutes using hydraulic fluid IAW MIL-
PRF-6083 with chamber pressure continuously being monitored. Isolate the chamber at proof
pressure with the chamber disconnected from the pressure source. Under that condition, the
pressure shall not drop more than 1 lbf/in2g for the first 30 seconds to allow stabilization of test
equipment; no pressure loss is allowed thereafter.
Low pressure chamber: Media proof. Test as above except low pressure port is connected to
high pressure port.
Electrical chamber: See table I.
Electrical connector: See figure 1.
Pressure port: See figure 1.
Media: Dry air; nitrogen; fuel IAW MIL-DTL-5624; oil IAW MIL-PRF-7808; or hydraulic fluid
IAW MIL-PRF-6083.
High temperature (operating and nonoperating): C (350°F).
Low temperature (operating and nonoperating): D (-65°F).
Altitude: C (70,000 feet).
Shock: C (100 G).
Vibration: S (test condition D, method 204 of MIL-STD-202).
Life mechanical: A (100,000 cycles).
Life electrical: C (50,000 cycles).
Acceleration: C (8 G).
Pulsation amplitude: A (0 percent).
Pulsation frequency: A (0 Hz).
Pressure rise: B (more than 1,000 lbf/in2/s).
Dielectric withstanding voltage (at reduced barometric pressure): Applicable.
Connector torque: Applicable.
Flame test: Applicable.
