Differ<strong>en</strong>tial Pressure Gauge<br />
Series GD40-2-01<br />
The pressure differ<strong>en</strong>tial at the<br />
inlet and the outlet of compressed<br />
air equipm<strong>en</strong>t can be viewed at a<br />
glance on the differ<strong>en</strong>tial pressure<br />
gauge. It is ideal for the maint<strong>en</strong>ance<br />
control of filters.<br />
Compact and lightweight<br />
Can be installed easily by merely<br />
providing a bypass circuit.<br />
Provided with a protective cover to<br />
prev<strong>en</strong>t hazards.<br />

Mounting<br />
Caution<br />
1. Mounting<br />
1) The HIGH and LOW marks on the back of the<br />
differ<strong>en</strong>tial pressure gauge indi<strong>cat</strong>e the high<br />
pressure and low pressure sides respectively.<br />
Connect the HIGH side to the inlet side of the<br />
filter or other devices and the LOW side to their<br />
outlet side. Do not use a stop valve to prev<strong>en</strong>t<br />
damage to the differ<strong>en</strong>tial pressure gauge if<br />
the valve is inadvert<strong>en</strong>tly left op<strong>en</strong> or closed.<br />
2) Install the differ<strong>en</strong>tial pressure gauge vertically.<br />
3) The piping of the differ<strong>en</strong>tial pressure gauge<br />
must be connected securely because it will<br />
break if it becomes detached.<br />
