Install in a convenient location and measure speed remotely using a sensor (sold separately).

Sensors generate a light beam across a 0.8" wide gap. When a rotating object enters this gap, the beam is broken.

Continuously measure the speed and running time of your engine to monitor its performance and detect mechanical issues early. These meters can be programmed based on engine run time to light up for maintenance reminders, such as oil changes, filter replacements, and inspections. Wrap the signal wire four to five times around your spark plug to secure it in place. They’re battery powered, so they will start showing readings as soon as you turn on the engine. It adjusts to nine different engine types for accurate readings. They’re rated IP67, so they won’t get damaged from dust and water.

Measure speed on an easy-to read digital display. Contact tachometers come in direct contact with the object measured and are an excellent choice for dirty and dusty environments.

This tachometer comes with a calibration certificate traceable to NIST that states it has passed a test for accuracy. Measure speed on an easy-to read digital display. Contact tachometers come in direct contact with the object measured and are an excellent choice for dirty and dusty environments.

Noncontact tachometers emit a beam of light or laser that reflects off a piece of reflective tape attached to the rotating point.

These stroboscopes come with a calibration certificate traceable to NIST that states they’ve passed a test for accuracy. They shine a bright flashing light at a moving object to make it appear slow moving. Use them to measure speed and to visually inspect belts and pulleys for signs of wear, such as cracking and fraying, without turning off the machine. They have a 1/4”-20 female threaded bushing for tripod mounting.

LED stroboscopes produce a brighter, more uniform light than xenon stroboscopes. They also consume less battery power and generate less heat.

Carry these stroboscopes when performing facility maintenance checks. Shine its bright flashing light at a moving object to make it appear slow moving. This helps you evaluate belts, pulleys, and other parts for signs of wear without shutting down your machines. It has a female threaded bushing, so you can mount it to a tripod to hold it steady.

Integrate these stroboscopes into fast-moving lines to check quality. They’re often used to inspect printed labels, rolled metal, and packaging. Channels on three sides allow you to attach them to T-slotted framing and other equipment. They shine bright and uniform pulsing light at moving parts to make them appear slower. This helps your machine vision camera and other digital inspection equipment identify defects. Connect them to sensors to trigger flashes at precise intervals in systems where timing and coordination are crucial. For synchronized usage along your line, you can daisy-chain multiple together. All come with a calibration certificate traceable to NIST that states they’ve passed a test for accuracy.

For visibility in all conditions, they have three light intensity settings. The lowest is often used for highly reflective surfaces, and the highest works well on dark and high-contrast materials. For quick changes between processes, their memory stores up to 10 light patterns.

Detect unwanted slowdowns in a rotary shaft that could cause machine damage and downtime. These switches are often used on drivetrains, conveyors, and other power-driven components. They come with a pulser disc, which you’ll need to attach to the shaft by drilling and tapping a hole. Once mounted, the disc rotates with the shaft and creates magnetic signals that the switch senses. When the speed falls below a set point, the switch will trigger an alarm or turn off the system.

Switches are UL listed and rated NEC Class I, Divisions 1 and 2, Groups C and D; and Class II, Divisions 1 and 2, Groups E, F, and G. They have an explosion-proof housing and are also rated NEMA 4X for washdown and corrosion protection.

These inductive proximity switches sense metallic objects each time they pass through the slot, even when they’re obscured by water, oil, dirt, or a surface finish. Use them to measure the speed of rotating equipment and to count or detect moving objects, such as sheet metal being fed into a stamping process. Send their signal to programmable logic controllers (PLCs) to support automated processes within your system. Switches are UL and C-UL listed, CE marked, and CSA certified, meeting strict domestic and international safety requirements. They’re also rated IP67 to protect against dust, washdowns, and temporary submersion.
