Tracking your machine component as it moves along a rotating threaded shaft, such as a spindle or lead screw, these indicators help you adjust machinery with speed and precision.

This digital readout system displays precise positioning on one axis. For use with machines that perform dry machining and cutting applications, such as table saws, band saws, planers, and drill presses.

Install a digital readout stop and fence system onto the setup for your miter, chop, or radial arm saw. It displays measurements on one axis, allowing you to cut pieces up to 94" with high precision.

Increase the accuracy of your manual machine when you fit it with a linear scale.

Reach deep into small holes and slots for precise depth measurements.

These gauges come with a calibration certificate traceable to NIST that states they've passed a test for accuracy.

Check measurements at a glance.

Built to resist corrosion and last in harsh environments, these vertical rulers are iron with a porcelain-enamel finish. Mount them to walls and tanks.

Permanently mount these vertical rulers to walls and tanks.

Fold these vertical rulers for convenient storage and transport.

Attach a plumb bob (sold separately) to the rope’s hook and lower it into your tank to take a measurement.

Align guide rails or lay pipe at specific angles from a flat surface.

These angle indicators display highly accurate angle, level, and tilt measurements.

At 2 1/4" square and 1" wide, this angle indicator easily fits into your pocket.

A ball inside a level tube indicates the side-to-side tilt angle.

Also known as angle finders, use these to gauge the angle of any surface.

An easy-to-read dial provides accurate settings for monitoring the number of wheel turns while manually adjusting valves, presses, and machine components.

Control devices with round or D-shaped shafts and view settings at a glance with a pointer.

Quickly identify equipment controls and components by their color. Use these knobs to control devices with round shafts and view settings at a glance with a pointer.

Mount these knobs into a threaded hole. Turn the knob to move the stud 0.005" per graduation and make precise adjustments.

Hardwire these switches to automatic door openers, electromagnetic locks, and electric strikes and your door will open at the touch of a button or the wave of your hand.

Align rotary shafts with the help of a mobile app.

Two chain clamps position two test indicators at different points along a shaft to find any misalignment.

Kits include two chain clamps, an inspection mirror, and a case.

These levels have a plastic housing.

Measure liquid level with sound waves—these transmitters don’t come into contact with the liquid so you don't have to worry about fluid compatibility or contamination.

For precise measurement of water, hydraulic fluid, or diesel fuel level, this gauge provides level readings down to 1/8".

Install these gauges through the top of your tank to monitor diesel, fuel oil, or gasoline level.

With a stainless steel float and float rod, these gauges resist corroding from chemicals.

Monitor hydraulic fluid or oil level in gear boxes, crank cases, and other reservoirs.

Made with clear, shatter-resistant plastic, these indicators don't require a shield to protect them like other oil-level indicators, so you can check your hydraulic fluid or oil level from any angle.

Bend these flexible indicators around the contours of your hydraulic fluid, oil, or water tank. Because their plastic resists shattering, they don’t need a protective shield like other liquid-level indicators, so you can check your tank’s level from any angle.

Avoid overfilling—these indicators pop up when your tank is almost full.

Use these gaskets with heavy duty level indicators to seal the glass.

Seal the glass on your level indicator.

Monitor liquid level in applications that have vibration, high pressures, and high temperatures. These indicators are also known as armored level gauges.

The nylon body and window make these indicators shatter resistant.

Use this gauge glass with heavy duty level indicators.

Measure the position of an object moving in a straight line. Also known as string pots, these transmitters have an extending wire cable that measures the relative distance between two points.

Easily mount these flat switches to a base or rail.

These intrinsically safe switches detect objects as they’re routed through the ring. They produce a low-current, low-voltage NAMUR signal, so they won’t ignite or create sparks. Switches are ATEX certified to protect against explosion.

The flexible cable on these switches withstands applications that require frequent motion, such as robotics.

Twist the sensor to detect metallic objects where explosive dust or gas may be present—the sensor rotates for front, side, top, or bottom sensing. These switches are UL and C-UL listed as well as ATEX and IECEx certified for hazardous locations.

Mount these intrinsically safe switches to flat surfaces in volatile areas. Their low-current, low-voltage NAMUR signal means they won’t ignite or create sparks while in use. ATEX and IECEx certified, they meet international standards to protect against explosion where combustible dust and flammable gases are present.

The short body on these switches makes them suitable for tight spaces.

Turn the face on these switches to sense metallic objects from the front, sides, top, or bottom.

For use in volatile areas, these intrinsically safe switches detect objects when they pass through the slot. They use a NAMUR signal to operate at a low current and voltage, so they won’t ignite or create sparks. ATEX and IECEx certified, they protect against explosion.

Rotate the face on these switches five different directions for easy installation and positioning—they work with both AC and DC inputs.

Switches accept both AC and DC input voltage.

Rated IP69K, these switches can withstand high-pressure, high-temperature washdowns and temporary submersion.

For optimal performance in tight spaces, these switches have a smaller beam and can detect smaller objects than standard photoelectric switches.

Set these switches to delay activation by up to five seconds after detecting an object.

A built-in relay produces AC voltage output. These switches are often used with older programmable logic controllers (PLCs).

Rated NEMA 4X, 6P, IP68 and IP69K, these switches resist corrosion and high-pressure, high-temperature washdowns, and can withstand temporary submersion.

These switches use a NAMUR signal to operate at a low current and voltage, so they won’t ignite or produce sparks. ATEX certified, they protect against explosion in environments containing flammable gases and combustible dust. Switches sense both metallic and nonmetallic objects.

Support flow and temperature control in your system with these intrinsically safe switches, which sense when a valve is open or closed in volatile areas. They are ATEX and IECEx certified to protect against explosion.
