  • Page 6: Overview

    OVERVIEW Overview The Weighlog 100 is intended for use on industrial and agricultural loaders; Such as Skid steers, Small wheel loaders and some Telescopic Handlers. It measures, displays and records the net weight lifted, based on the lift system hydraulic pressure.
  • Page 7 OVERVIEW The Weighlog system consists of a number of standard kits, which are designed to fit a wide range of loaders. Mounting positions will vary according to the type of machine, however this manual gives general guidelines that apply to all machines. The installation may require some modification of the brackets provided for mounting the reference/direction sensors.

  • Page 8: Load Sensor Installation

    LOAD SENSOR Load Sensor The load sensor (fig. 2a) is connected by a flexible hose into the pressure side of the hydraulic circuit, using a tee fitting. Depending on the machine, you may be using a threaded tee piece, SAE flange coupling, or if there is no suitable coupling you may have to drill and tap into a suitable point.
  • Page 9 LOAD SENSOR Installing the Load Sensor The load sensor contains a snubber to protect if from shock loading. This consists of a diagonally drilled hole 0.3 mm in diameter. It is possible to block this hole with debris causing the sensor to malfunction. If a load sensor is installed on a machine where there may be particles of debris in the oil, or the installer is unable to ensure the components being installed are kept clean, it is advisable to pre fill the flexible hose with clean oil.
  • Page 10 LOAD SENSOR SAE Flange Coupling Install the 1/8" x 1/4" BSP adaptor and Dowty seal to one of the two 1/8" BSP ports on the flange. Install the plug with Dowty seal to the remaining BSP port (Fig1). Loosen and remove the four flange bolts and split the coupling.
  • Page 11 LOAD SENSOR Mounting the Load Sensor Connect the hydraulic hose to the tee fitting and route the hose towards the sensor mounting location. Connect to the load sensor and mount the sensor in a well protected area, one that can also be accessed for servicing.
  • Page 12 Reference/Direction Sensor Reference/Direction Sensor First establish the most convenient weighing position. If possible sensor position should be at the middle of the lift height. In some cases this is not possible. Position the sensors so the weight reading will be obtained as high as possible .The sensor and magnet must be arranged so the magnet is opposite the sensor face at the weighing position.
  • Page 13 Reference/Direction Sensor Reference/Direction Sensor Mounting 3. Assemble the Reference/Direction clamp assembly as shown. The bracket is designed so that the sensor may be installed on either side of the machine, by rotating the angle bracket 90 degrees.Remove the original M8 bolt from the green nylon clamp, and replace it with longer M8 x M60 mm.

  • Page 14: Ref/Dir Sensor

    Reference/Direction Sensor Reference/Direction Sensor Mounting Magnet mounting Mark the hole positions drill and tap 2 holes M6 in the lift arm for the magnet bracket. In some cases the magnet can be mounted directly onto the lift arm but you must install the fiber washer between the magnet an the lift arm. Install the bracket and attach the magnet using the stainless steel screw and the fiber washer between the magnet and bracket.
