FMA SERIES MICRO FORCE SENSORS FOR USE IN INDUSTRIAL KNITTING MACHINES
The FMA Series may be used in industrial knitting machines to monitor the yarn/thread tension, helping to provide feedback for precise control.
- Used in thread tension monitoring feedback loop to ensure the correct amount of force is being applied under all conditions
- Provides more accurate control of the feedback loop where response time is critical
- Provides multiple digital addresses on the same bus
- Monitors many different thread tensions at once
- Minimizes thread tension concerns, resulting in less scrap due to garments ruined by incorrect thread tension
- Minimizes machine downtime due to broken threads
- Small size allows many sensors to fit into small space
- Cost-effective solution to the load cell sensors that are usually used to measure
thread tension
The FMA Series piezoresistive-based force sensors offer a digital output for reading force over the specified full-scale force span and temperature range. They are fully calibrated and temperature compensated for sensor offset, sensitivity, temperature effects, and nonlinearity using an onboard Application Specific Integrated Circuit (ASIC).
The direct mechanical coupling allows for an easier interface with the sensor (using tubing, membrane, or a plunger), providing repeatable performance and a more reliable mechanical interface to the application. These sensors offer a more stable output that is directly proportional to the force applied to the mechanically coupled sphere.
The digital I C interface permits multiple addresses on the same bus, allowing the use of multiple sensors and helping to reduce system complexity. The optional internal diagnostics function enables fault detection.
