R55 Series robust Square Drive Torque Sensor


Made in the USAThe versatile R55 Series torque sensors are developed for inline use with square drives on both ends. It comes in a range of 6 capacities up to 550 Nm.

With a female square on the bottom and a male square on top in a range from ¼” to ¾” this sensor fits a torque wrench for inline measurements and can be used in combination with an optional AC1010 tabletop mounting kit to use it for calibration purposes.

The rugged setup and limited size of the R55 make it suitable for multiple applications from laboratory and industrial to field service use and for calibrating torque tools to using a standard socket wrench as a precise torque wrench.

An R55 sensor requires an I3, I5 or I7 indicator (sold separately) and is part of the Plug & Test® system family. Sensors with Plug & Test®  store calibration and configuration data in its internal PCB, this provides the opportunity to calibrate and configure sensors and use them on any I series indicator without re-calibration or re-configuration.

Delivery includes a certificate of calibration which contains 10 data points in each measuring direction.

We are happy to assist you in finding the most suitable configuration for your needs. Please contact us for more information.  


Features
  • Compatible with the 7i, 5i and 3i digital indicators
  • NIST-traceable certificate of calibration included
  • Square drives on each end
  • Stainless steel and aluminum construction
  • Unique Plug & TestTM connector holds all calibration and configuration data
  • Rugged cylindrical design

Plug &Test® Smart Force & Torque Sensors

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.
