ABB PFTL201D is a high precision pillow-block tension sensor adopting Pressductor magnetoelastic technology. It is specially developed for tension detection on various material processing lines. This sensor can accurately measure horizontal tension while excluding the interference from roller weight. Made of stainless steel with fully sealed structure, it features high rigidity, excellent sensitivity and long-term operational stability. It usually works together with tension amplifiers to convert original signals into standard signals for control systems, and performs reliably in complex industrial working environments.

PF represents the Pressductor force measurement series of ABB. TL stands for tension load cell. 201 refers to the product series of pillow-block sensors for horizontal force measurement. D indicates the specific mechanical configuration equipped with detachable cannon connectors for field wiring connection. Different load specifications are available to meet diverse on-site requirements.

This sensor applies magnetoelastic measuring principle. It supports multiple nominal load ranges for selection. The allowable extended load reaches one hundred and fifty percent of full scale, and the ultimate load can reach three hundred percent of full scale. The comprehensive measurement error is controlled within a small range with high accuracy. The excitation power supply ranges from 5 V DC to 15 V DC. The operating temperature ranges from minus 20 degrees Celsius to 60 degrees Celsius. The overall protection class is IP65. The shell is made of stainless steel, and the internal insulation resistance maintains a high level. It adopts standard pillow-block installation structure.

It is fitted with a cannon connector for connecting shielded signal cables. The sensor outputs millivolt bridge signals directly. When matched with a supporting tension amplifier, it can provide standard analog signals including 4 to 20 milliamps and 0 to 10 volts. It also supports access to common industrial fieldbus protocols for digital data transmission. Shielded twisted pair cables are recommended for signal wiring to guarantee transmission quality.

It achieves high-precision real-time detection of material tension on production lines. It effectively eliminates the influence of roller weight to ensure pure tension measurement. Built-in temperature compensation design reduces signal drift caused by temperature changes. The product has strong overload and impact resistance to adapt to dynamic working conditions. The sealed structure prevents dust and liquid from entering the interior. It can be well connected with various control systems to realize closed-loop tension control.

It is widely used in tension monitoring and control for metal strip rolling and processing lines in metallurgical industry. It applies to all kinds of paper making machines for web tension detection. It is also suitable for production lines of plastic film, aluminum foil, wire and cable. In addition, it can be deployed on slitting, laminating and winding equipment in printing and material processing industries.

Mount the sensor on a rigid equipment frame and keep horizontal installation to avoid extra side load. Use matched shielded cables and fix the connectors properly with strain relief devices. Arrange signal cables separately from power cables to reduce electromagnetic interference. The product is fully calibrated before delivery, and fine adjustment of zero point and range can be completed through the supporting amplifier. Keep the sensor surface clean and dry, and avoid violent impact and excessive vibration. Inspect connectors and cables regularly for wear and corrosion. When replacement is needed, replace the whole unit and perform matching calibration again.
