Measuring system · SMS Compact
Small and medium springs, measured compactly.
The SMS Compact measures compression and extension springs without contact, using a laser line sensor from Micro-Epsilon. It needs a footprint of only 900 × 600 mm and has an interface to WAFIOS iQ.

Application
For compression and extension springs in many shapes.
The SMS Compact complements the large SMS for suspension springs. It measures smaller springs up to 250 mm long, from fine wire of 1.5 mm to heavy wire of 20 mm.
Spring shapes
- cylindrical
- conical
- double-conical
- barrel-shaped
For suspension and axle springs up to 650 mm high: to the SMS

Evaluation
Evaluated in InnoMeas.
Like all Qsigma systems, the SMS Compact works with InnoMeas. The software evaluates the spring, shows the results colour-coded and passes them on to your systems.
