Force Measurement Instrumentation 101

/0 Comments/in , /by

There are many types of instrumentation devices used in force measurement applications. Interface provides high-quality instrumentation tools to use with our wide range of load cells and torque transducers.

The variety of instrumentation solutions includes signal conditioners, output modules, high-speed data loggers, portable load cell indicators, weight indicators, and junction boxes.

Depending on the application requirements, Interface has solutions for full-data acquisition as well as wireless technology telemetry systems. Our multi-channel bridge amplifier has 4-channel capability, while the INF-USB2 universal serial has a sensor to USB output converter.  With more than 50 instrumentation products, the solutions range for all types of uses.

To provide you with more insight, here’s an overview of a few of Interface’s instrumentation offerings along with educational video demonstrations to help you.

4 Channel 9840-400-1-T Intelligent Indicator 

The Model 9840 is TEDS plug-and-play ready! It is suitable for use in calibration labs, field service, or anywhere high accuracy is important.  This intelligent digital indicator has auto-setup for multiple load cells with fast, direct analog output.  Features include two interactive 7″ graphical touch screen displays, remote sense, low noise, 24-bit internal resolution. It has a USB port with RS232 communication, mV/V calibration and can store calibrations for up to 25 sensors.  This unit also has self-calibration and is TEDS plug and play ready and IEEE 1451.4 compliant. It is fully compatible with the Gold Standard® Calibration Systems.

DIG-USB Output Module

Interface’s DIG-USB Module is a compact, high-precision strain gage converter used for converting a strain gage sensor input to a digital output. It connects to a computer via a USB port. This product allows high precision measurements to be communicated directly to a computer and is aimed at applications which require high-accuracy measurement repeatability. With the appropriate drivers installed, the DIG-USB appears as a virtual serial port to the computer.

Simply by plugging the device into a computer, data can be extracted from most strain gage bridge input sensors and acquired by software which allows data manipulation removing the need for amplifiers, filters, and multi-meters.

9890 Strain Gage Indicator

Our 9890 Strain Gage Indicator is a full-featured multipurpose and easy-to-use digital strain gage and load cell meter ideal for weight and force measurement applications. With a max current of 350 mA at 10 V, it can support up to twelve 350 Ω load cells (minimum load resistance of 28 Ω), making it ideal for multipoint weight measurement applications. It accepts mV input signals up to 300 mV (unipolar) and ± 250 mV (bipolar). The 9890’s powerful dual-scale capability allows the measurement to be displayed in two different units of measure.

This video provides an overview of the 9890 Strain Gage Indicator and how it works.

920i Programmable Weight Indicator/Controller

The Interface 920i instrumentation device is a programmable, multi-channel digital weight indicator and controller. The configuration can be performed using the front panel, with an attached USB-type keyboard (or PS/2 keyboard if using a serial interface), or by using the iRev 4 utility. Model 920i is bidirectional and comes in a NEMA 4X stainless enclosure. Standard options include 8,000,000 internal counts, 4.6 x 3.4-inch LCD 7-digit display and a measurement rate that goes up to 960 Hz. Options are available that allow you to include analog and relay outputs.

This video provides an easy-to-follow getting start guide for the 920i Programmable Weight Indicator/Controller.

These are just a few of the dozens of instrumentation solutions Interface offers, all designed for unique application needs.  For more information on Interface’s instruments, visit our web product page or review our product brochure for detailed specifications on every product.

Introducing Interface’s Upgraded 4 Channel Intelligent Indicator

/0 Comments/in /by

Interface has been leading the way in force measurement innovation for the last 50 years, and over the course of our history, we’ve been consistently developing and improving upon our solutions.

A perfect example of this focus on continuous improvements and innovation is seen with our 4 Channel Intelligent Calibration Grade Indicator Model 9840-400-1-T. This solution is ideal for anyone who needs to calibrate a load cell with a single, double or triple bridge. And it just got some impressive new upgrades.

The new version of the 9840-400-1-T Intelligent Indicator features a more modern digital display with additional channels available. It’s now easier to use, with the same high stability and industry-leading performance as the older version of the 9840. Although the quality is the same as our older version, the update can be easily integrated with Interface’s Gold Standard® system and frames, as well as with Microsoft’s Windows® 10.

Interface’s 4 Channel Model 9840-400-1-T allows single loads with three measurements to directly compare outputs to Interface’s Gold Standard load cell, and all measurements can be captured through Interface’s Gold Standard software. This allows users to compare multiple load cells and gather data on whether the load cells are accurate or out of calibration. The 4 Channel Model 9840-400-1-T solution also has the option for high-level input channels.

The Model 9840 is already being used in more than 300 labs, most of which have highly-specific metrology requirements.

‘It is the choice for many aerospace and metrology labs that do in-house calibrations because of its reputation as one of the most accurate calibration tools on the market.” Ken Bishop, Director of Sales Engineering, Interface

Other industries that have expressed great satisfaction with the Model 9840 [user_id], including those in test and measurement and automotive.

The 4 Channel 9840-400-1-T features include two Interactive 7″ graphical touch screen displays, remote sense, low noise, 24-bit internal resolution, USB port with RS232 communication, mV/V calibration, store calibrations for up to 25 sensors. 6-point linearization, unit conversion, and front-panel tare. This unit also has self-calibration via TEDS Plug and Play ready IEEE 1451.4 compliance.

For anyone in need of a metrology-grade digital intelligent 4 channel solutions for high-end readings, Interface has the answer. To learn more, visit 4 Channel 9840-400-1-T or call 480-948-5555 to speak to our application engineers.
