Bend-and-Stay Positioning Arms

Stronger and with greater load capacities than gooseneck-style positioning arms, these arms keep their shape even when moving or when exposed to vibration. They’re often used in robotics and conveyor applications when frequent repositioning isn’t required.

All accessories include the necessary hardware for attaching them to arms.

Economy Electronic Plunger Variance Indicators with Flexible-Arm Magnetic-Base Holder


	Side View

Bend and flex the arm of the base to position your indicator—these holders have ball-and-socket segments that lock in place with a lever. The base is magnetic and has a V-groove on the bottom for a solid mount on flat and curved metal surfaces. Flip a switch to release the magnet.

A spring-loaded plunger extends and retracts from the indicator to take measurements. The measurements display on an easy-to-read LCD screen. Press the zero-set button to start measuring at any point. They have zero-position memory, also known as absolute (ABS) positioning, which retains the measuring position when the indicator is off.

All can send data to your computer using a USB cord (sold separately). They have SPC data output to wirelessly transfer your measurement data to your device with the push of a button.

IP67 Enclosure Rating—IP67-rated indicators seal out coolant, water, and dust, so you can take measurements in dirty machining environments.

Bluetooth Connection—Indicators with Bluetooth can transfer your measurement data wirelessly to your device with the push of a button. You'll need a data transmitter/receiver set (sold separately).

Tolerance-Checking Go/No-Go Operation—Indicators with tolerance-checking go/no-go operation inform you when an item falls outside your set measurements.

Dial Plunger Variance Indicators with Precision Weighted-Base Holder

A granite base stabilizes these indicators. The extremely tight flatness tolerances of the granite allow for nearly frictionless workpiece movement and provide an accurate reference plane for inspection work.

Indicators have a continuous dial numbered clockwise around the face for taking direct measurements. Rotate the dial face for viewing at multiple angles. All come with calibration certificates traceable to NIST that state the indicator and the granite base have passed a test for accuracy. They have jeweled bearings that are highly sensitive and wear resistant for a long service life.

Economy Dial Lever Variance Indicators with Jointed-Arm Magnetic-Base Holder

Position the arm by adjusting joints at the top, middle, and bottom. The magnetic base has a V-grooved bottom for mounting on flat and curved metal surfaces and a magnetic release switch for easy setups. Use the fine-adjustment knob on the holder’s clamp for precise positioning of the indicator.

Also known as a test indicator, the indicator has a lever-style contact point that pivots as it comes into contact with a surface and a balanced dial with positive values on one side and negative values on the other side. It has jeweled bearings for high sensitivity, wear resistance, and a long service life. Rotate the dial face for viewing at multiple angles.

Economy Dial Plunger Variance Indicators with Flexible-Arm Magnetic-Base Holder


	Side View

Measure in almost any position—these variance indicators have an adjustable ball-and-socket arm that locks in place with a lever. With a magnetic V-grooved base, they mount securely to both flat and curved metal surfaces. A spring-loaded plunger retracts and extends to measure objects. These indicators have a continuous dial numbered clockwise around the face, so it’s easy to see how much a dimension increases. Adjust the tolerance pointers to mark measurements that fall outside your limits. For quick dismounting, the base has a magnetic release switch.

Economy Dial Plunger Variance Indicators with Clamp-On Holder


Side View	Plier Clamp	C-Clamp

Often used where space is tight or there’s not much of a surface for mounting, the clamp on these indicators fits where a weighted or magnetic base can’t. The clamp also gives you the option to directly mount these indicators to a machine or the piece you’re measuring. With the ball-and-socket segmented arm, you can adjust the indicator to nearly any position to keep it from obstructing what you're measuring. Pull the lever to lock the arm in place when you're done. To measure objects, these indicators have a spring-loaded plunger that retracts and extends as the surface varies. It’s easy to see how much a measurement increases, since the dial is continuous and numbered clockwise around the face. Adjust the tolerance pointers to mark measurements that fall outside your limits.

Plier Clamp—Indicators with a plier clamp work on most thin, flat surfaces.

C-Clamp—Indicators with a C-clamp apply less pressure than indicators with a plier clamp, so there’s less risk of damaging a workpiece.

With adjustable magnetic pins that conform to any shape, the base on these variance indicators mounts securely to uneven surfaces. The ball-and-socket arm is highly adjustable and locks in place with a lever, so it holds the indicator in almost any position. For quick dismounting, the base has a magnetic release switch.

A spring-loaded plunger extends and retracts to measure objects. The measurements are displayed on an LCD screen. Start measuring at any point by pressing the zero-set button. They have zero-position memory, also known as absolute (ABS) positioning, which retains the measuring position when the indicator is off.

All can send data to your computer using a USB cord (sold separately). They have SPC data output to wirelessly transfer your measurement data to your device with the push of a button.

IP67 Enclosure Rating—IP67-rated indicators seal out coolant, water, and dust, so you can take measurements in dirty machining environments.

Bluetooth Connection—Indicators with Bluetooth send measurement data to your device wire-free and without an additional device.

Tolerance-Checking Go/No-Go Operation—Indicators with tolerance-checking go/no-go operation inform you when an item falls outside your set measurements.

Economy Jointed-Arm Weighted-Base Variance Indicator Holders

Stabilize and precisely position your indicator with these weighted bases. Attached to the base, these holders have a jointed arm for moving your indicator up and down and in and out. Tighten the knob on the arm to lock it in place and use the fine-adjustment clamp for angling your indicator just right. Made of granite, the base has an extremely tight flatness tolerance, so it creates an accurate reference point for inspection work. It also means you can easily slide your workpiece in and out.
