Transmitter NBOX

The instrument is a precision transmitter for weighing and force measurement systems using load cells. The instrument allows to acquire analog cells separately (up to a maximum of 8 cells).

The instrument converts the mV signal of the load cells into a high resolution digital signal (24 bit) for each single cell, the sum of the points will then give a more precise information of the acquired weight value.

The transmitter can be integrated as a slave in different types of networks, through various Serial or Fieldbus communication protocols.

MOUNTING OF THE LOAD CELL

General precautions to be followed in the installation and assembly of load cells:

Follow the direction of application of force on the load cell
Do not exceed the limits of the temperature as indicated in the data sheet
Do not remove labels from the load cell
Adequately protect the cables with sleeves or channels
Carry out on each load cell a ground connection with suitable cable, shunt on mounting accessories
Do not carry out any welding on the mechanical structure after mounting the load cell
Avoid or reduce to a minimum level any mechanical constraints between the rigid structure and the weighing structure to avoid error in weighing and return to zero
In case of vibration or dynamic loads product the load cells with puffers / shock absorbers
Protect load cell from any dust accumulation with any appropriate means
