Axial-Tension Sensor Product Description |
The FA9219 series shaft-through tension sensors operate on the resistance-strain principle, offering exceptional accuracy in measuring tension across belt-type materials. When integrated with constant-tension automatic controllers, magnetic powder brakes, and clutches, they form a comprehensive tension control system that enables closed-loop regulation. These sensors are widely employed in electronic control systems for gravure presses, slitting machines, dry coating machines, and vacuum coating machines.
Axial-Tension Sensor Function Feature |
High-performance strain gauge measurement element with accurate and stable signals, minimal thermal deformation, and excellent long-term stability
manufactured from aluminum alloy, featuring dustproof, waterproof, and corrosion-resistant design with optional addition of a waterproof valve, making it cost-effective and practical.
Featuring a shaft-type structural design with single or dual-side openings, it offers convenient installation, rapid response, and high measurement accuracy
Sensors with various axial diameters ranging from 17 mm to 35 mm are available.
10-fold overload capacity, zero-point stability, and no need for sensor recalibration.
The tension sensor features a high spring constant, enabling accurate measurement even during high-speed operation of the roller.

Frequently Asked Questions about Axial-Tension Sensor |
Q1：What shaft diameters are supported?
A:Standard shaft diameters include:
Other shaft sizes can be customized according to customer requirements.
Q2：Can the FA9219 work with tension controllers?
A:Yes.
The sensor is commonly integrated with:
to achieve precise closed-loop tension control.
Q3：Is the sensor waterproof?
A:The standard protection level is IP50.
Higher waterproof protection can be customized by adding waterproof sealing, making the sensor suitable for more demanding industrial environments.
Q4：Does the weight of the roller affect measurement?
A:No.
When measuring horizontal tension, the weight of the roller does not influence the measurement result, ensuring high accuracy during operation.
Q5：Can the sensor be installed on either side of the machine?
A:Yes.
The shaft tension sensor can be installed on either the inside or outside of the equipment frame, depending on the machine design. Single-side and double-side opening structures are both available.
