MIL-PRF-25435D
3.4 Interface.
3.4.1 Dimensions. The transmitter case shall conform to the dimensions in Figure 1.
3.4.2 Pressure indicator. The transmitter shall be designed for operation with indicators
conforming to the requirements of MIL-I-25437.
3.4.3 Vent connection. The vent pressure connection shall have a threaded boss in accordance
with SAE AS5202-04 shown in Figure 1. The connection shall withstand a 25 foot-pound
bending moment applied in any direction perpendicular to the longitudinal axis of the connection
without distortion of the base plate, damage to welds, or change in calibration.
3.4.3.1 Vent markings. The vent connection shall be permanently marked VENT, with the
letters clearly visible and easily readable.
3.4.4 Electrical connector. The transmitter shall have an MS33678R10SL-3P electrical
connector. The connector shall withstand a 25 foot-pound bending moment applied in any
direction perpendicular to the longitudinal axis of the connector without distortion of the base
plate, damage to welds and electrical connections, or change in calibration.
3.4.5 Power supply. The transmitter shall operate from a 25 ± 2 V, 400 ± 10 Hz, single-phase
power source. The positive side of the power supply shall be connected to pin B of the
transmitter connector and the ground side connected to pin A. The power supplied shall conform
to MIL-STD-704.
3.5 Environmental conditions. The transmitter shall operate under the following conditions:
a. Operational temperatures ranging from -65 to 330°F and storage temperatures from
- 80 to 450°F
b. Sinusoidal vibration up to 30g at frequencies from 5 to 2,000 Hz.
c. Pressure equivalent to an altitude of 100,000 feet and temperature of -65°F
d. Relative humidity up to 95%
3.6 Performance.
3.6.1 Operating position. The transmitter shall operate in either the vertical or horizontal
position.
3.6.2 Dielectric strength. There shall be no insulation breakdown when a potential of 200 Volt
root mean square (Vrms) at 60 Hz is applied between any electrical connector pin and any metal
part of the transmitter case.
