The 7i professional digital force / torque indicator is designed to work with a wide range of Mark-10 remote force and torque sensors. With exclusive Plug & Test technology, all calibration and configuration data is saved within the sensor’s smart connector, not the indicator, allowing for true interchangeability. In addition, all sensors are fully compatible with other Mark-10 indicators.
The 7i features an industry-leading sampling rate of 14,000 Hz, producing reliable results for extremely quick-action tests. In addition to the 5i indicator's functions, the 7i features high speed continuous data capture and storage, with memory for up to 5,000 readings, at an acquisition rate of up to 14,000 Hz. The 7i also features programmable footswitch sequencing, break detection, and 1st / 2nd peak detection. Coefficient of friction unit of measurement and a user-defined unit of measurement add flexibility for specialized applications. For productivity enhancement, the indicator also features automatic data output, data storage, and zeroing functions upon the completion of break detection, averaging, external trigger, and 1st / 2nd peak detection.
The 7i interfaces with Mark-10 motorized test stands to permit functions such as break testing, dynamic load holding, PC control capability, and more. The included MESUR Lite data acquisition software tabulates continuous or single point data. Data saved in the indicator’s memory can also be downloaded in bulk. One-click export to Excel easily allows for further data manipulation.
Focus on Engineering: Specialized Gauge Functions
The 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
The7i 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 MESURTM gauge for further analysis and graphing. Using a 7i could replace cumbersome and expensive data acquisition hardware and software.
Footswitch Command String
Integrate your footswitch / automation system with a 7i indicator 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 7i can perform the following automatic functions:
(1) Save the peak reading to memory,
(2) Transmit the peak reading via USB, RS-232, or Mitutoyo output (3) Zero the display, and (4) Toggle an I/O pin, for example to stop movement of a Mark-10 motorized test stand.
Applicable events include:
(1) Sample break detection (also applicable to samples which slip, click, or otherwise reach a peak, then fall), (2) Completion of an averaging sequence, (3) External trigger (ex. switch activation), and (4) 1st / 2nd peak capture (ex. torque tool testing, tensile testing).
User-defined Unit of Measurement
The 7i displays 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:
(1) 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.
(2) 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.
