About us

Do you have a specific task? We will get back to you with a recommendation.

octogon GmbH in Leoben, Austria, develops, manufactures and calibrates sensors for force, load and weight. Our roots are in sensor manufacturing: we supply load cells, force transducers and load pins as standard designs from stock or manufacture them as custom designs to your drawing. We also supply the matching measurement electronics and sensors for pressure, level, temperature, flow, torque and strain.

Design, CNC machining, strain gauge application, electronics and calibration laboratory are all under one roof. So you talk to the same people, whether it is an item from the shop or a transducer that does not exist yet.

1 N to 50 MN

measuring range of our load cells and force transducers

more than 400 products

in the shop: load cells, force transducers, electronics and sensors

from quantity 1

custom design as a single piece, prototype or series

ISO/IEC 17025

calibration for force, length and mass in our own accredited laboratory

Under one roof in Leoben

A spring element tolerates no deviation: every inaccuracy in its geometry shows up later as a measurement error. That is why we mill and turn our spring elements ourselves, apply the strain gauges in our own workshop and calibrate in our own laboratory.

What we do for you

Besides the shop, we work on tasks for which there is no catalogue item:

Custom force transducers

to your drawing, from the free initial concept to the calibrated series

Load pins

replace an existing pin and measure directly in the load path

Strain gauge application

your component in the load path becomes the transducer

Electronics development

amplifiers matched to design and signal, also inside the transducer

Calibration service

for load cells and force transducers to ISO/IEC 17025

Test bench construction

for development, quality assurance and series testing

CNC contract machining

milling and turning to your drawing, with the standards of sensor manufacturing

On-site measurement

measurements directly in your plant, without removal and shipping

Residual stress analysis

with the hole-drilling method and X-ray diffraction (XRD)

How we work

  • Data sheet and delivery time for every item. Most prices are shown directly in the shop; for everything else we send you a written quotation.
  • Technical advice from the people who design and manufacture. You describe the task, we propose the right transducer and electronics.
  • Certificates where they are required: explosion protection to ATEX and IECEx, functional safety up to SIL 3 / PL e, protection up to IP69K, calibration certificate to ISO/IEC 17025. More under Quality and certifications.
  • Replacements for sensors from other manufacturers. If a type is discontinued or the lead time is too long, we find a suitable replacement, see Replacing a load cell or force transducer.
