quick install

1. Select a location for the installation suitable to the gauge’s physical dimensions that will allow access to the display and keypad. Plan for a ¼" M-NPT connection or a hose to a ¼" tting.

2. Thread the gauge onto the tting. Apply tightening torque only to the metal wrench ats, not to the PD housing. Use a 5/8” wrench. Do not overtighten.

3. Wire the device. See the wiring diagram in this guide.

4. Remove the protective lm from the gauge front.

5. Program the gauge.

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 specied 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.

Allow space to turn the PD Analog onto the pipe or tting during mounting. The PD is delivered with the connector attached to the device.

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.

Note: For out-of-scale pressure read ings, output can go as low as 3.5mA or as high as 24m A.

full-scale/high-end pressure

The minimum loop supply voltage is calculated from the formula:

= 7.5V + (20mA * total loop resistance).

min

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.
