TC series load cells are strain gauge transducers used to
measure loads in static and dynamic applications, in tension
(positive signal of output) and compression (negaitive signal
of output), with high accuracy (industrial weighing, laboratory
testing, automation, etc).
The TC series is machined from a single block of metal, so
the primary sensing element, the mountings and the case
contain no welds allowing smaller dimensions and an enhan­ced grade of protection.
The configuration of the point of measurement, with 8 strain
gauges, reduces errors caused by imperfect application of the
load.Typical applications of load cells connected in parallel
are: silos, hoppers, large weighing platforms, and with suita­ble accessories, suspended loads. The stainless steel con­struction is suitable for use in aggressive environments in the
chemical and petrochemical industries.

CONVERSION TABLE

If the transducer is supplied complete with
prewired connection cable, the colour code is that
indicated in the table.

Cells connected in parallel

In systems that use several cells, the parallel connection automatically sums the loads on each individual cell.
Using this method of measurement, the maximum load will be the sum of the loads on the individual cells and the
sensitivity will be the average value of these cells.
It is important that the user ensures that no cell is stessed beyond its maximum rating under any load condition.

* The screen is isolated from the transducer body.
It is recommended that the screen is connected to
ground at the instrument end.
