Looking for low-cost load cell with intergrated 4-20mA amplifier

[JesperMP]

Hi all.

(I may actually have asked about this is the past, but I cannot find that thread again. I have searched for it with no success.)

I am looking for an inexpensive load-cell with integrated 4-20mA amplifier.
The loadcell should be of the tension type with eye-lets at both ends.
Also preferably with an M12 connection rather than a fixed cable.
I want to cut costs by eliminating the typical external box with a loadcell converter.
The measuring range will be around 500 kg, and precision can be "relaxed". 0.5%-1% is "good enough".

Any ideas ?

Hi osman.

These threads are about a load cell converter.
I am looking for a load cell with integrated converter.

Hi Osman.

This is HBMs main product page. Do you have any particular loadcell in mind ?

A loadcell with USB interface !?
Interesting, but I need a loadcell with 4-20mA to go into a standard analog PLC input.

go to weigh modules maybe there,only reference

HI Osman.

I use HBM loadcells already, so I dont need a link to their general product page.
Besides, it does not look like they have anything of the kind of what I need.

The Mostech sensor you linked to comes very close to my requirements.
Unfortunately it comes only as pressure, and not as tension variant.

Hi Jesper,

The only ones I know of are not cheap, and are from Alfa Laval.

Is this what you are looking for?

None so far with integrated converter.

I swear I have seen one once with integrated 4-20 mA converter.

Futek has an inline amplifier. This comes close to what you're looking for.
