1.2 Pressure Sensor Installation
The pressure sensor reads the main line pressure of the lift cylinder (hydraulic line). Only one sensor is required;
however, the WLS-C Wheel Loader Scale may be used with two pressure sensors if needed. There are two
options for pressure sensor installation:
• Install a flange block where the hydraulic line attaches to the hydraulic fluid distributor. Use one of the
fittings supplied to attach the sensor to the flange block. The kit comes with a few common fittings
which fit the majority of wheel loaders. It may be required to locate special fittings for the installation.
See Figure 1-5 through Figure 1-8 for a list of provided fittings.
NOTE: Some manufacturers do not use flange blocks. In these cases, use a swivel T-fitting.
• Attach the weld-on flange (supplied, see Figure 1-7 4) directly to the hydraulic line. This should be
performed by a qualified welder to ensure proper fitting and seal.
Note: The best source for flange blocks is the local heel loader or skid steer dealer that sold the machine originally. An
alternative source for flange blocks is www.mainmfg.com/mainhome.html.
