Model-7i Advanced Force/Torque Indicator


Made in the USA

The Professional Model-7I Digital Force/Torque Indicator is the highest specification of the Mark-10 Indicator range.
Based on the Series-7 Force Gauge it shares most of its specifications and is is compatible with a large range of motorized and manual test stands like the ESM and F series.
It uses the interchangeable Plug & Test® sensors that allows a system range of 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. 
The M7I Indicator has a sample rate of 14.000Hz and can store up to 5000 data points with continues data capture.

Data connectivity is provided through RS-232, Mitutoyo (Digimatic), USB or analog outputs.

The Digital Mark-10 Force/Torque Indicator Model is 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 a system with a Plug & Test® sensor they are combined with additional equipment to a purposely build test setup to perform the required tasks.

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

Plug & Test® 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.

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). 

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.

Specialized Gauge Features

The Model-7I Indicator features several functions typically found in more complex instruments, such as materials testers, data acquisition systems, and PLCs.

The following unique features are highlighted:

High Speed Data Capture & Storage
Model-7I can capture and store up to 5.000 continuous data points at a rate of up to 14.000 readings per second. This unique function is ideal for capturing switch activation forces, sharp breaks, and other short-duration applications. Configurable start and stop triggers are provided. The data acquisition rate is variable and can be slowed to also capture longer events, such as structure relaxation, material expansion, and others. Data from the storage buffer can be exported to data collection software such as MESUR®gauge for further analysis and graphing. Using a Model-7I gauge could replace cumbersome and expensive data acquisition hardware and software.

Footswitch Command String
Integrate your footswitch / automation system with Model-7I gauge to improve testing ergonomics and efficiency; no need for multiple key presses. Up to three steps may be programmed for a single footswitch activation. Select from several commands, including request peak reading, zero the display, save to memory, and others. Time delays can be inserted between each step.

Automatic Data Output / Save / Zero / I/O Pin Toggle
Upon completion of several event types, the Model-7I can perform the following productivity-enhancing functions:

  • Automatically save the peak reading to memory.
  • Transmit the peak reading via USB, RS-232, or Mitutoyo output.
  • Zero the display. Toggle an I/O pin, for example to stop movement of an ESM303 test stand.

Applicable events include:

  • Sample break detection (also applicable to samples which slip, click, or otherwise reach a peak, then fall).
  • Completion of an averaging sequence.
  • External trigger (ex. switch activation).
  • 1st / 2nd peak capture (ex. tensile testing).

User-defined Unit of Measurement
Model-7I gauges display 6 standard units of measurement. One additional user-defined unit is provided for unique applications. A base unit is specified, along with a multiplier, and 5-character name. Typical applications:

  • To measure the torque produced by pressing on a lever in a mechanical assembly, configure the multiplier based on the length of the lever, thereby converting a unit such as N into Ncm.
  • To measure the pressure produced by a circular compression plate on a foam sample, configure the multiplier based on the area of the plate, thereby converting a unit such as lbF into psi.
