ABB PFTL301E Pressductor® PillowBlock Horizontal‑Force Web Tension Load Cell

Horizontal web‑tension measurement: Detects horizontal force exerted by running web material on the measuring roller, converts mechanical tension into proportional millivolt‑level sensor signal for external tension amplifier (e.g. PFEA111‑112).
High‑stable force sensing: Magneto‑elastic principle, minimal deflection (<0.13 mm), low drift, free from frequent recalibration, excellent repeatability (<±0.1 % FS).
Strong overload resistance: 300 % nominal‑load overload capacity on measuring direction; tolerates large transverse side‑force from misaligned web materialABB Group.
Harsh industrial environment adaptability: Rugged metal housing, IP65 protection grade, wide operating temperature range (−20 °C ~ +80 °C), anti‑vibration for continuous production line operation.
Standard pillow‑block mounting: Interchangeable installation dimension with conventional pillow‑block bearings; directly fitted at both ends of measuring roller shaft, easy mechanical retrofitting for existing machines.plcva.com
Signal output to upper‑level system: Sends raw tension signal to ABB tension amplifier, further converted to 4‑20 mA analog signal for PLC, DCS or closed‑loop tension controller.
Fault‑resistant performance: Insensitive to dust, moisture and mechanical wear; long service life for 24‑7 continuous production.plcva.com
