Description
Product Introduction
ABB PFTL301E5KN is a pillow-block tension sensor based on Pressductor magnetoelastic technology. It is designed for horizontal tension measurement on various production lines and eliminates the influence of roller weight during measurement. With an all-stainless steel fully sealed structure, the sensor features high rigidity, high precision and stable long-term performance. This model has a nominal load of 5 kilonewtons and is applicable to medium and heavy tension working scenarios. It usually works with supporting signal amplifiers to transmit valid data to industrial control systems.
Model Interpretation
PF represents ABB Pressductor force measurement series. TL stands for tension load cell. 301 refers to the compact horizontal pillow-block tension sensor series. E indicates the version with factory fixed integrated cable. 5KN means the nominal measuring load is 5 kilonewtons. The complete model code is used for product identification, ordering and inventory management.
Technical Parameters
The sensor adopts magnetoelastic measuring principle. Its nominal full scale load is 5 kilonewtons. It can withstand 150 percent extended load and 300 percent ultimate load. The overall measurement error is kept within a low range to ensure high accuracy. The excitation voltage ranges from 5 volts DC to 15 volts DC. The operating temperature ranges from minus 20 degrees Celsius to 60 degrees Celsius. The protection class is IP65. The housing is made of stainless steel, and the internal insulation resistance maintains a high level. It adopts standard pillow-block installation structure.
Interface and Communication Configuration
This sensor is fitted with factory fixed shielded cable for signal transmission and has no detachable external connector. It outputs millivolt bridge signals directly. When connected with a matched tension amplifier, the original signal can be converted into standard analog signals including 4 to 20 milliamps and 0 to 10 volts. It can also connect to common industrial fieldbus to realize digital data transmission. Signal cables should be laid separately from power cables to reduce electromagnetic interference.
Core Functions
It performs real-time and accurate detection of horizontal tension of moving materials. It isolates the interference from roller weight to guarantee authentic tension data. The built-in temperature compensation design effectively reduces signal drift caused by ambient temperature changes. The product has strong overload and anti-shock capacity to adapt to complex dynamic working conditions. The sealed structure protects internal components from dust and liquid intrusion. It can cooperate with various control systems to realize closed-loop tension control.
Application Scenarios
It is widely used for tension monitoring and control on papermaking production lines. It is suitable for processing lines of plastic film and metal foil. It can be applied to tension detection in wire drawing and winding processes of wire and cable industry. It also fits slitting, laminating and winding equipment in material processing industry. Besides, it works well on medium and heavy load web handling production lines in general industrial fields.
Operation and Maintenance Instructions
Mount the sensor on a rigid equipment frame and keep it horizontally installed to avoid extra side load. Arrange and fix the integrated cable properly, and prevent sharp bending and pulling. Provide the sensor with specified DC excitation voltage. The product is fully calibrated before delivery, and on-site zero and range adjustment can be completed via the matched amplifier. Keep the sensor clean and dry, and avoid violent impact and long-term excessive vibration. Inspect the cable and housing regularly for wear, aging and corrosion. Replace the whole sensor unit when permanent faults occur, and carry out recalibration after replacement.
