MIL-DTL-9395/29C
REQUIREMENTS:
Dimensions, weight and electrical schematic: See figure 1.
Calibration: See tables I, II, III, and IV.
Proof pressure: 250 psig high over low and simultaneously.
System pressure: 125 psig high over low and simultaneously.
Burst pressure: 500 psig high over low and simultaneously.
Electrical ratings:
Operating voltage: 28 V dc.
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 a hydraulic fluid per MIL-PRF-
6083 with chamber pressure continuously being monitored. Isolate the chamber at proof with the
chamber disconnected from the pressure source. Under that condition, the pressure shall not drop
more than 1 psig 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): D (-65°F).
Altitude: D (100,000 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%).
Pulsation frequency: A (0 Hz).
Pressure surge: B (more than 1,000 psi/sec).
Dielectric withstanding voltage (at reduced barometric pressure): Applicable.
Connector torque: Applicable.
Flame test: Applicable.
Explosion: Applicable.
