Analysing the movement of rotating machines is quick and easy with our Handheld Tachometer. The Handheld Tachometer is equipped with 3 high-power LEDs, which together generate a light intensity of 11730 lux at 20 cm / 1000 Hz.The Handheld Tachometer allows you to precisely set the flash frequency in both FPM and Hz. The Handheld Tachometer is pocket-sized and is also mains-independent thanks to the rechargeable battery.
The Handheld Tachometer is operated intuitively using the 10 keys, allowing quick adjustments to be made. The phase shift allows the observation point to be moved variably. The pulse width can be used to set the duration and thus also the intensity of the flash frequency. The display brightness can be selected in the settings menu, as can switching off the display after a period of inactivity, which extends the battery life. The Handheld Tachometer is supplied with a USB-C charging cable in a service bag.
When the input trigger mode is activated, the device synchronises the flash frequency of the LEDs based on the input trigger signal provided (or with the output trigger signal). A rising or falling edge of the signal to be synchronised can be selected. In output trigger mode, the device generates a PWM signal with the selected frequency, the selected duty cycle and the selected phase shift.
Route measurement mode makes it possible to use a number of predefined settings for frequency, duty cycle and phase shift and to navigate from one point to the next without having to manually set the values at each point. The device allows the storage of up to 15 routes with a maximum of 10 machines per route and a maximum of 5 points per machine.
Handheld Tachometers are indispensable tools for monitoring and inspecting production facilities, e.g. in the printing and textile industries but also for general maintenance and inspection tasks in all industrial sectors. They also enable non-contact speed and vibration measurement: if the flash frequency of the Handheld Tachometer matches the frequency of movement, the measured object appears stationary.
