The Laser Trigger RPM Sensor acquires the signal optically using a red laser. The laser beam exits from the sensor head and hits a measuring mark on the rotating shaft. The measuring mark can be light-increasing (e.g., reflective foil T5) or light-reducing (contrast mark, e.g., black line on bright surface).
Whenever the sensor acquires a brightness difference, it outputs an electrical pulse. Based on the repetition rate of the voltage pulses, the measuring device calculates the shaft speed.
No maintenance is possible for this sensor. Moisten a clean, lint-free cloth with water to clean the optical lens. Avoid direct contact with the lens. Do not use alcohol for cleaning!
TRANSPORTATION AND STORAGE
• Put the sensor, cable and stand in the measuring device case.
• Short-circuit the magnetic pole at the stand using the washer.
The laser trigger / RPM sensor (in short: sensor) is used as trigger for vibration measurements and for RPM measurements using a measurement data collector.
• Read these instructions carefully prior to use.
• Use original accessories only.
• Do not use defective sensors.
• Do not open the housing.
• Prior to the installation of measuring components, switch off the machine and secure it against restarting according to the applicable regulations.
• Comply with the applicable safety regulations when performing measurements on machines.
• Check that the measuring setup can move freely prior to restarting the machine. Avoid contact of the measuring
setup with rotating machine parts. Risk of injury and property damage!
• For storage and transportation, short-circuit the magnetic pole at the stand using the washer supplied. This is to minimize the magnetic field strength.
• The sensor is in compliance with the relevant European Directives.
