Description
Rated load: 1.0 kN; maximum allowable overload: 1.5 kN; ultimate breaking load: 3.0 kN. Measurement accuracy: ±0.5 % full scale; repeatability: 0.1 % full scale.
Stainless‑steel construction, protection class IP65. Operating temperature range: ‑20 ℃ ~ +80 ℃. Built‑in precision strain‑gauge bridge circuit, outputs millivolt‑level analog signals. Raw output cannot be directly connected to DCS analog input modules, external PFEA amplifier is required. Excessive lateral force will introduce measurement errors.
Mechanical tension force from the roll shaft acts on the PFTL101A load cell, causing tiny deformation of internal strain gauges, which generates bridge output proportional to applied tension. Normally two sensors are installed at both ends of the roll shaft, and their signals are summed to calculate total web tension.
Zero adjustment, span setting and fault diagnosis are all completed on the PFEA amplifier unit; no calibration function is available on the sensor itself. It is suitable for low‑to‑medium tension measurement scenarios.
Cannot operate independently. Junction box and matching tension amplifier are necessary for connection to upper‑level control equipment.
Difference compared with PFCL201C series: PFTL101A adopts strain‑gauge principle with compact size, for light‑duty tension; PFCL201C uses magnetostrictive Pressductor technology and features much higher overload resistance for heavy‑duty conditions.
Mount on rigid supporting base. The roll shaft end shall apply compressive force vertically onto the sensor measuring surface. Bending torque and torsion load are prohibited. Mounting base deformation will directly cause measurement deviation. Use dedicated shielded signal cables and separate them from high‑power cables to minimize electromagnetic interference. Zero‑point and span calibration must be performed at amplifier side after sensor replacement.
Paper machines, plastic film, aluminum foil, textile and non‑woven production lines, used for roll‑mounted web tension detection and closed‑loop tension control.
- ABB Millmate PFTL101A 1.0kN strain‑gauge tension load cell for light‑to‑medium web tension measurement.
- Compact stainless‑steel housing, IP65 protection rating, suitable for industrial dusty and humid environments.
- Millivolt‑level bridge output; PFEA tension amplifier is mandatory, direct connection to DCS AI cards is not permitted.
- Typically installed in pairs at two ends of measuring roll to obtain total web tension value.
