OMEGA’s DFG55 advanced digital force gauges are designed for tension and compression force testing in numerous applications across virtually every industry. With capacities from 0.12 to 500 lb (0.5 to 2500 N) the gauges feature an industry-leading sampling rate of 7000 Hz, producing accurate results even for quick-action tests. Accuracy is ±0.1% of full scale ±1 digit, and resolution is 1/5000.

A large, backlit graphics LCD displays large, legible characters, while the simple menu navigation allows for quick access to the gauges’ many features and configurable parameters. Data can be transferred to a PC or other data collector via USB, RS232, Mitutoyo (Digimatic), or analog outputs.

On-board data memory for up to 1000 readings is included, as are statistical calculations and output to a PC. Integrated set points with indicators are ideal for pass-fail testing and for triggering external devices such as an alarm, relay, or test stand. The gauges are overload protected to 150% of capacity, and an analog load bar is shown on the display for graphical representation of applied force.

The DFG55’s averaging mode addresses the need to record the average force over time, useful in applications such as peel testing, while external trigger mode makes switch activation testing simple and accurate.
