The Basic Model-3I Force/Torque Indicator is developed as a versatile measurement device and in combination with an external sensor can be used for a wide range of applications.
With its compact design, similar to the Series-3 Force Gauges, the Model-3I features a sampling rate of 2.000 Hz, supports 3 units of measurement and can be connected to a PC via a USB connection.
Force/Torque Indicators are used in combination with Plug & Test® sensors, one indicator can therefore be used for a variety of applications and load ranges based on the sensor used.
The Model-3I shares most of its specifications with the Series-3I Force Gauges and can be used in combination with a wide range of test stands and gripping fixtures.
A backlit LCD display shows all the setting and current measurement information and it can be connected to a PC using the included MESUR® Lite data acquisition software.
The Digital Mark-10 Force/Torque Indicator models are available in a variation of 3 gauges and each compare largely with the similar numbered Force Gauge version.
The main difference is the use of a separate Plug & Test® sensors. One of the unique features of the Plug & Test® sensors is that they have their own PCB which stores the calibration and configuration data.
A Plug & Test® sensor can be switched to a different Indicator without the need for calibration or re-configuration.
The difference between the 3 Indicators can be found in the table below which shows the main specifications of each gauge type.
All gauges types are equipped with a rechargeable battery and a back lit display.
The indicators can be used for measuring tension, compression and torque depending on the type of sensor.
All Indicators come with MESUR® Lite data acquisition software.
MESUR® Lite tabulates continuous or single point data. One-click export to Excel allows for further data manipulation.
Mark-10 Digital Indicators are versatile instruments, in general they are combined with additional equipment to a purposely build system to perform the required tasks.

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.
As an alternative to the Plug & Test® sensors a PTA/PTAF Plug & Test® adapter can be used to connect common strain gage-based load cells, force sensors, and torque sensors to Models M7I, M5I, and M3I indicators and Series F test frames. Sensor capacity and resolution is configured via an included software utility, which includes a library of common force capacities from 0,5 N to 4.000 kN (0.12 to 750,000 lbF), and torque capacities from 7 Ncm to 57.000 Nm (10 ozFin to 40,000 lbFft).
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.
