ABB PFTL101A 3BSE004172R1 Steel Belt Type Weighing/Tension Sensor

ABB PFTL101A 3BSE004172R1 Steel Belt Type Weighing/Tension Sensor
I. Basic Model Information
Model: PFTL101A
Material Order Number: 3BSE004172R1
Product Series: ABB PFTL Tension Measurement Unit (Special for Metallurgical Cold Rolling / Hot Rolling Lines)
Category: Strain-type Steel Strip Tension Sensor, used in conjunction with PFE101 Amplifier Transmitter

Core Function
Used for real-time measurement of roll tension in metal strip rolling machines, shearing machines, and coating units. Installed below the tension roller bearing seat of the rolling machine, converting mechanical tension into standard electrical signals, achieving closed-loop control of the rolling machine tension stability, avoiding strip breakage, wrinkles, and uneven thickness.

Key Specification Parameters
Range Specifications (PFTL101A)
Rated Load: 1kN (100kgf), the same series has different range models such as 2kN/5kN/10kN that are not interchangeable
Sensing Principle: High-precision strain gauge bridge measurement, steel strip elastic body structure, resistant to lateral force and impact
Output Millivolt Signal: Sensitivity 2mV/V, requires external PFE101 signal amplifier to convert into 4–20mA standard signal for PLC/DCS
Power Supply (Amplifier Side): 24VDC Mechanical structure
Integrated stainless steel elastomer, waterproof and resistant to rolled emulsion
Standard flange mounting holes, directly replace the old tension sensor
Environmental conditions
Operating temperature: 0 ~ +70℃
Resistant to oil, cooling water, and high dust and humid environment of the rolling mill
Protection: IP65
