DescriPtion
PD analog digital pressure gauges are media isolated, so they can be used with any
gas, liquid, or solid compatible with 17-4 PH stainless steel within the specified
pressure range. The transducer consists of a one-piece, high-strength pressure sensor
that uses no silicone oils, welds, O-rings, or seals. The sensor is coupled to a 4-20 mA
loop powered internal display and keypad. The keypad controls setup and operation
of the sensor as described below.

Electrical
Select a loop power supply voltage and total loop resistance such that when the loop
current is 20 mA, the gauge will have at least 7.5 VDC at its terminals. Too large a loop
resistance will cause the gauge output to "limit" or saturate before reaching its full
20 mA output.
The minimum loop supply voltage is calculated from the formula:
V
min
= 7.5V + (20mA * total loop resistance).
If the loop voltage drops too low, the PDxAM will display the LOW LOOP icon. At this
time, all calibration functions are disabled.
The LCD is loop-powered. If no voltage is applied, or if the connector is removed, the
display will be blank.
