The air pressure gauge will read wet or dry air pressure. The sender used
for this gauge is an oil pressure sending unit, so it is compatible with air, water,
oil, and fuel. The air pressure gauge will operate and read correctly between the
pressure range of 0 - 145 psi. The gauge has a user adjustable low and high
warning level.
Operation:
The gauge needs only the Red and Black wires connected to light up.
When the Blue wire has 12 volts, it will dim the display for night viewing. The
Gray, Purple, Orange, and Green wires are for the pressure senders.
The
senders must be Dakota Digital part SEN-03-1.
Sending units from other
manufacturers will cause incorrect readings. SEN-03-1 has 1/8” NPT threads. If
other thread sizes are needed, an adapter fitting should be used to change the
thread size. If a sender is giving an incorrect reading, the display will show “EE”.
If the sender is shorted to ground, the display will show “--”.
Pressing the switch on the front of the gauge will change the display to the
next reading. With four senders, the left side pressure will be displayed on the
left side and the right side pressure on the right. An “F” or “R” will be displayed in
the center for Front or Rear. With two senders the pressure will be displayed on
the left side and “FRNT” or “REAR” will be displayed on the right.
The display will flash whenever one of the displayed pressures is out of
the warning set limits.
