Table 31. Hale Water Column Pressure Sensor Wiring (From/To Listing)
From Pressure Transducer Pin To MIV-Auto Module Connector B Pin
A (+ 5V Reference) 11 (+ 5V Reference) [Output]
B (Reference Return) 12 (5V Reference Return) [Output]
C (Water Column Signal) 5 (Water Column Signal) [Input]
Both sensors require 5.0 VDC (called power or reference above) and system ground to operate.
The nominal output signal is linear between 0.5 VDC and 4.5 VDC, where:
•
0-5 psiG sensor
•
a signal voltage of 0.5 VDC equals 0.0 psiG
• a signal voltage of 4.5 VDC equals 5.0 psiG
•
0-300 psiA sensor
•
a signal voltage of 0.5 VDC equals 0.0 psiA
•
a signal voltage of 4.5 VDC equals 300.0 psiA
NOTE
All legacy Akron Brass Swing-Out™ Valve pressure transducers (A93001003) must be
replaced with Hale sensors. See paragraph 4.7.3.1.1.
4.7.3.1 AB Swing-out Valve Pressure Sensor
The SAM system utilizes a Hale pressure sensor rated to 300 psi mounted close to each dis-
charge valve. The sensor must be mounted 45° from horizontal therefore it is typically mounted
using a 45° adapter. (Typically, a discharge valves pressure tap is either horizontal or vertical; no
matter the valve position; the sensor needs to end up 45° from horizontal.) Electrically the sen-
sor connects to the motor driver on the valve it is installed in (see Figure 49 and Table 29,
above) via the AB factory cable.
