AEP transducers / TRX / Torque transducer

TRX series torque meter has been designed to perform torque measurements both in clockwise and anticlockwise direction with a high precision.
Main fields of application vary from the industrial one on test benches and materials test machines to the most strictly metrological sectors such as first line samples for test and calibration laboratories, research bodies etc. ..
Used also as transfer samples for evaluating the uncertainty of direct weights test benches or for comparison among the different reference National Institutes.
Manufactured in two main accuracy classes 0.05 or 0.1 according to EURAMET cg-14 norm with a yearly drift lower than 0.003%
Measurement stability is ensured even in wet and hard environments thanks to a high protection grade realized though LASER welding which guarantee the tightness.
The monolithic body, entirely made in stainless steel, guarantees a high resistance to dynamic stress which can occur in both measurement directions.
Torque meter is manufactured in 3 specific structures in order to cover a very wide range up to 5000 N•m.

(1) Percentual errors referred to reading, min. 1/10 of the nominal load.
For correct measurement both axial and transverse forces and bending moment should be absent.
In case of presence, they must not be greater than values indicated below, to be reduced in simultaneous presence of more solicitations.

Electrical Connections

PVC 80°C shielded cable, Ø 5.2mm with 6 tinned Ø 0.25mm2 conductors.
