TSA Tension Sensor
Overview
Applicable to a wide range of materials, and in tension control in industry sectors that will support the next generation!
The TSA tension sensor is a high-performance unit that uses a strain gauge system. The sensor has a high spring rigidity, high resonant frequency, and very little displacement even at high tension levels. This means that the TSA tension sensor is ideal not only in the tension control of paper and PET film, but also for applications in industries that manufacture highly functional films, low-stretch webs and high-value-added products. Nireco also offers an intrinsically safe explosion-proof TSA tension sensor that can be installed in hazardous locations where the atmosphere is explosive.
Intrinsically safe explosion-proof model
Information about "intrinsically safe explosion-proof"
The intrinsically safe TSA tension sensor is installed in hazardous locations where there is the risk of flammable or explosive gas or steam. The tension controller, tension display and power supply are located in a non-hazardous location where there is no hazardous gas or steam. A safety barrier is installed between the tension sensor and these other devices, to maintain a state of safety.
Feature
- High spring rigidity
The sensor's high spring rigidity means that its resonance is high, which makes it ideal for high-speed lines. - Little displacement under loads
As there is very little displacement under load, the TSA sensor is well suited to thin web lines, such as film and foil. - Excellent performance
The sensor's strain gauge system yields superior linearity and hysteresis. - Mounting compatibility
The TSA has the same external dimensions as the earlier MB tension sensor, making retrofitting simple.
* Cabling will need to be converted or replaced.
* May not be possible for all models.

| Note *1. Values for rated tension, permissible roll weight and allowable overload are those applicable in double-sided detection. The figures for single-sided detection are 1/2 of these values. *2. The allowable overload indicates the permitted force applied in the direction of the resultant tension. *3. The resonant frequency listed is that during double-sided detection when tension is at its maximum and when the roll weight is at its maximum. *4. The response time is that value measured when the tension change is 1/10th of the rated tension. | ||||
