The sensor is connected to the pneumatic suspension of a vehicle, and measures the current pressure in system. The pressure proportional to the load on the axle. In the simplest case, it 1 sensor on the rear suspension of the truck is enough. However, if there is a need to improve the accuracy, you can mount the sensor on the front suspension too.
After installation, you must hold a calibration (load truck with cargo portions of given weight). No need to make calibration immediately. It can also be performed during operation of the vehicle.

Calibration table must be recorded in AVL software or GPS tracker.

There is several methods of mounting this sensor.

Method 1 (without mounting kits).

This installation option is available when air suspension has plugs for connection of sensor directly into the threaded hole M16 × 1,5. In such cases, these openings can be set using a pressure sensor and a sealing washer ring bundled with the sensor.

Fig 1 - Installation under method 1

Method 2 (using the mounting kit "M22")

This installation option is not verydifferent from the first for him the only difference is that in some vehicles plugs and valve control output installed in the threaded holes M22 × 1,5, so to install the sensor need to acquire additional adapter nut, washer and ring installation diagram will look as shown in Figure 2.

Method 3 (using the universal mounting kit)
This installation option involves the installation of a pressure transmitter into air system with a tee adapter like shown on fig.3.

kit (A) and on vehicle (B)

Method 4 (using the universal mounting kit)
This installation option involves the installation of  tee adapter into air system pipe directly. This option is recommended if you can use  regular hole like in Method 3.

Method 5 (using the universal mounting kit)
Recommended for use in case of inability to use the installation method described above. In this way, installation increases the complexity and increases the number of mounting locations, which reduces the reliability of the pneumatic vehicle system.
