Sensors


Proximity Sensor	Optical Sensor

Magnetic Sensor

Measure speed remotely using a sensor.

Proximity Sensor—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—Magnetic sensor has a maximum measuring distance of 0.005" from a 0.1" minimum size ferrous metal target.

Optical Sensor—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.

IP67 Enclosure Rating—They’re rated IP67, so they won’t get damaged from dust and water.
