5 Tension ranges available from 0 - 50 cN up to 0 - 1000 cN

Stationary electronic tension sensors for measuring sensitive materials as optical fibres, carbon fibres, technical fibres etc.

Large, smooth running guide rollers for minimized material deflection with 32 mm groove Ø

Low cost tension sensor for quick and easy mounting

Special Features

Tension sensor FSL with integrated measuring amplifier and high accuracy of 1.5 % FS
Large bending radius for gentle handling of sensitive material by using smooth running, V-grooved guide rollers with Ø 29.5 mm, ball-bearing mounted
Various output signals are avilable:
– analog: 0 – 1 V DC (standard), 0 – 10 V DC (optional)
– digital (optional): USB, WiFi, RS 422 – see model FSL-422
– current: 4 – 20 mA (optional)
Easy installation, even afterwards, on existing machines
2 Mounting possibilities: housing mounting or cylindrical hole mounting (mounting cut out 38.5 – 40 mm Ø) – see picture above.
The housing of sensors with digital output are larger and need as mounting cut a longhole R 19 with a length of 54 mm
Easy calibration to customized material by operator – zero and gain calibration is required
With high quality strain gauge bridge
Tension sensor with mechanical overload protection
Standard Features
Tension sensor FSL with aluminium housing
Required power supply +15…24 V DC (regulated)
Certificate of Compliance with the order 2.1 according EN 10204 is included
Optionally available: Inspection Certificate 3.1 according EN 10204 with calibration report
