U-Force Slim-line Mechanical Force Gauge

The Model U Force Gauge is an accurate (±1% of full range) mechanical compression measurement instrument. Its slim-line design has repeatedly proven valuable in installations where space is at a premium.

The versatility of this simple instrument is demonstrated by the fact that it can be used as a hand-held device, permanently mounted on a flat surface plate, or used in test fixtures.

The Model U Force Gauge employs a deflection beam machined from aircraft quality alloy steel and heat-treated to develop optimum strength and spring characteristics. A precision dial indicator is mounted at the null point of this beam.

The compression force is normally applied against a single pressure fitting mounted on the upper half of the beam. When load is exerted, the beam moves downward causing a slanted anvil on the free end to push against the indicator plunger. The indicator reading is a direct representation of the applied load.

U-Force Gauges are available for measurement in pounds or kilograms. There are 6-pound capacities ranging from 25 x .25 to 5,000 x 50 lb. The 4 kilogram capacities range from 10 x .1 to 500 x 5 kg.

We also offers high-capacity gauges with pounds capacities from 500 to 5,000 lb and a metric model with a capacity of 500 kg. High-capacity gauges all have a flat-bottom design.

NIST Traceable Calibration Certificate is included.

Options

  • Zero position - The zero position on the indicator dial can be factory positioned at 12 o'clock, 3 o'clock, 6 o'clock, or 9 o'clock. The standard position is the 12 o'clock position.

  • Maximum load pointer — Model U Force Gauges can include a maximum pointer which remains at peak load until it is reset.

  • Shockless dial indicator — Offers added protection in applications where force is applied or released rapidly.

  • Dial orientation — The dial indicator can be factory positioned at 0° (standard), 90°, 180°, 270° clockwise. Photos on this page show standard dial orientation.

Note: Maximum Pointer and Shockless Dial Indicator cannot be offered on the same unit.

How the U-Force Works

U-Force Slim-line Mechanical Force Gauge Callout
1. Deflection beam
2. Dial indicator with zero at standard 6:00 position
3. Pressure fitting
4. Maximum load pointer (optional)
5. Indicator plunger
6. Slanted Anvil

Compression force is normally applied against a single pressure fitting mounted on the upper half of the beam. (For accurate calibration, designate the type of pressure fitting you wish to use with the U Force Gauge. They are of four types: domed, cupped, flat, or a flat nylon insert. (Flat bottom gauges require only one fitting)

When load is exerted, the beam moves downward causing a slanted anvil on the free end to push against the indicator plunger. The indicator reading is a direct representation of the applied load.

Pressure Fittings

Load is applied tot he U-Force through harded pressure fittings.

Replacement fittings for:
Recessed-bottom - two fittings
Float-bottom - - one fitting

Fittings are not included. Choose fittings from the below list.
