The R50 Series Universal Torque Sensor measures in both directions with a capacity range from 7 to 1150 Ncm. The robust aluminum housing and the ability to use it as a portable as wel as a, in combination with a torque test bench, fixed device make the R50 suitable for a large variety of applications.
The R50 torque sensor contains a Jacobs chuck for measuring samples up to 12.7 mm in diameter (depending on the capacity) and is compatible with the Series 7i, 5i and 3i torque Indicators (sold separately).
Thanks to the unique Plug & Test technology, sensors can be interchanged easily. The internal PCB saves the calibration and configuration of the sensor.
The R50 can, be used in combination with a digital Indicator and a TSTM-DC motorized torque test stand to form a complete torque test system.
We are happy to assist you in finding the most suitable configuration for your needs. Please contact us for more information.
General information
Mark-10 M7I, M5I, and M3I indicators are used in combination with Plug & Test® sensors and can therefore accommodate numerous force and torque measurement requirements, from 1 N to 50 kN (0.25 to 10,000 lbF) of force, and from 7 Ncm to 550 Nm (10 ozFin to 5,000 lbFin) of torque.
Plug & Test® sensors can be used handheld or mounted to a fixture or test stand for more accurate and repeatable testing results.
The sensors are separately calibrated therefore they can be disconnected from one indicator and connected to another without the need for re-calibration or re-configuration as this is stored in the PCB located inside the smart connector.
Accuracy
System accuracy is determined by the combination of Indicator and sensor combined. To determine the total system accuracy the accuracy value of the sensor is added to the value of the indicator.
As the Indicators have different accuracy values the total system accuracy may vary between the different indicator/sensor combinations. Indicator Model Accuracy M7I / M5I ±0,1% of full scale M3I ±0,2% of full scale.
Example 1 Model MR01-100 sensor with Model M5I Indicator MR01-100 ±0,15% of full scale + M5I ±0,1% of full scale = Total ±0,25% of full scale This translates into a fixed error of up to: 0,25% x 500 N = 1,25 N
Example 2 Model MR50-50Z sensor with Model M3I Indicator MR50-50Z ±0,35% of full scale + M3I ±0,2% of full scale = Total ±0,55% of full scale This translates into a fixed error of up to: 0,55% x 50 Ncm = 0,275 Ncm
Because accuracy is defined as a percentage of full scale, the fixed error is possible anywhere on the scale from 0 to the capacity. As such, this value represents an increasingly large error as percentage of reading towards the low end of the scale. It is, therefore, recommended that a sensor is selected with capacity as close as possible to the expected load. The resolution may be different for some sensors depending on whether a M7I, M5I, or M3I indicator is being used. For example, a Series R01 force sensor will display finer resolution when connected to a M5I indicator than when connected to a M3I indicator.
