nnnn

General

nnnn

The TVN load cell is composed of a nickel-plated steel body and is fully

nnnn

sealed by welded dishes. The TVN load cell is leak tight (according to

nnnn

IP 67) and compact. It is available in 7 capacities, namely : 50, 100,

nnnn

200, 500, 1 000, 2 000 and 5 000 kg.

nnnn

Description

nnnn

The principle used by the TVN load cell is measurement of the

nnnn

deformation of a beam to which a shear force is applied. It uses strain

nnnn

gauges installed as a Wheatstone bridge to convert the force into an

nnnn

electrical signal.

Applications

nnnn

Mechanical assembly

nnnn

The TVN load cell is installed using two ball joints with lock nuts*.

nnnn

Electrical assembly

nnnn

The load cell outputs a low amplitude analogue electrical signal.

nnnn

Therefore, some particular precautions need to be taken for the

nnnn

electrical connection.

nnnn

-É Systematically connect the shielding of the load cell in the

nnnn

connection box or onto the indicator.

nnnn

-É Keep the load cell cable away from elements that could cause

nnnn

serious electromagnetic disturbances. Avoid routing the power

nnnn

cable and measurement cable adjacent to each other.

nnnn

-É Keep the measurement part away from any heat source, or protect

nnnn

it.

nnnn

* Optional.
