High-Accuracy Panel-Mount Tachometers with Certificate of Calibration
Accurate to within ±0.001% of reading, these tachometers come with a calibration certificate traceable to NIST that states they’ve passed a test for accuracy. Install in a convenient location and measure speed remotely using a sensor (sold separately). Use the buttons on the front panel to program the unit.
Proximity sensor detects moving metal objects, such as gear teeth and fan blades and can be used in dirty and wet environments. Maximum measuring distance is 0.2" from a 1/2" minimum size metal target.
Magnetic sensor has a maximum measuring distance of 0.005" from a 0.1" minimum size ferrous metal target.
Optical sensor performs best in clean environments and works at up to a 45° angle from reflective tape.

Tachometers/Hour Meters for Gas Powered Engines
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.

Surface-Mount Stroboscopes with Certificate of Calibration
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.

Tips measure the rotational speed of shafts and other spinning objects. Tips for flat-end surfaces are often used with pulleys and circular saws. They have a concave surface to fit flush over bumps, such as screw heads. Tips for shafts with center hole are cone-shaped, so they’ll fit the inner diameter of different hole sizes.
Speed wheels measure the length and speed of conveyor belts, bolts of fabric, and material on spools. They have a grooved edge to fit over wire, cable, and cords.

Speed-Monitoring Switches
Set to a specific speed to detect unwanted machinery slowdown that can cause damage and downtime. Applications include drive trains, power-driven components, and conveyors. Switches are UL listed for 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.

Slot DC Metallic-Object Proximity Switches
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.

Hazardous Location Slot DC Metallic-Object Proximity Switches
Commonly used to measure the speed of motors and other rotating equipment in the oil and gas industry, chemical plants, and grain mills, these switches detect objects each time they pass through the slot. Switches are intrinsically safe and produce a low-current, low-voltage NAMUR signal, so they won’t ignite or create sparks while being used. ATEX and IECEx certified, they meet international standards to protect against explosion in environments containing flammable gases and combustible dust. Prior to use, these switches must be connected to the required barriers (sold separately), which reduce the current and voltage coming from your power source. Unlike the switches, barriers must be installed in a separate nonhazardous area.
Also known as inductive proximity switches, they sense metallic objects even when they’re obscured by water, oil, dirt, or a surface finish. Send their signal to programmable logic controllers (PLCs) to support automated processes within your system. Switches meet various national and international safety standards, and they’re rated IP67 to protect against dust, washdowns, and temporary submersion.
