Force Measurement Instrumentation 101

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.

9860 High Speed Digital Indicator

Recently updated with new software, Interface’s Model 9860 High Speed Digital Indicator features an internal, high gain, fully differential amplifier with a 16-bit analog-to-digital converter combined to accurately digitize the input signal. The analog input is digitally filtered, with user-selected sample size and filter window (band), allowing optimization for specific operating conditions. With this model, self-calibrating ±10Vdc and 4-20mA analog output signals are standard. This product has an RS232 interface, which gives the instrument the ability to communicate, command, query operating modes and parameters and to continuously read data.

The Interface Transducer Electronic Data Sheet (TEDS) status indicator on the Model 9860 provides the information on the configuration of the input. A front panel RCAL switch provides a convenient calibration feature. Both calibration functions are easily performed via front panel pushbuttons.

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.

Watch this video for a getting started demonstration with the DIG-USB Output Module.

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.
