Indicator RIN1-PL

RIN1-PL is a load limiting system for dual channel connection for load cells. The cell must be double bridged in the case of systems where Performance Level PL d is required.

In the SIL 2 compliant version, in accordance with category 2 according to EN 13849-1: 2016, PL d (corresponding to SIL 2, EN62061 standard), the load limitation is implemented by means of relays, of which the BLOCK is a safety relay with guided contacts, monitored in real time, according to the EN50205 standard.

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
