What is your definition of the specific energy consumption?

1)energy consumption of the compressor as a function of the pressure.

2)energy consumption per conveyed mass in kWh/ton

Ad1) The energy consumption of the compressor is normally stated in the data sheet. However, mostly only for the maximum pressure. The supplier can give you the required information at your request or you calculate the compressor yourself. In the latter case, use the appropriate formula for the type of compressor.

Ad2) Divide the value, obtained under Ad1) by the conveyed mass.

Alternatively, measure in the electric motor supply.

You can to analyze the consumition power of motor connecting ammeter with gripper. And then to calculated the kW use this: P=(3^0,5)*I*V*cos(fi).

calculated how many kW there are during one hour and then divide por product transported during this hour
