MM-0360  CCLD Laser Tacho Probe

CCLD Laser Tacho Probe MM-0360 is especially designed for contact-free speed measurements on rotating or reciprocating machine parts. MM-0360 produces a voltage pulse for each rotation of a shaft or cycle of a machine part.

MM-0360, used with retroreflective tape like the included QS-0056, has the advantage that it can be located any distance from 1.5 to at least 70 cm (0.6 to 27'') from the test object, thus safely separating the probe from possible contact with moving parts or an otherwise hazardous environment.

사용

  • Non-contact measurement of rotational speed
  • Synchronisation between rotating or reciprocating machine elements and measurement instruments
  • Low-speed measurements to 0 RPM* for wind turbine and ship propulsion applications
  • High-speed measurements up to 300000 RPM for supercharger measurements
  • Small size for measurements in tight locations

*Measurement down 0RPM requires DC coupling of the CCLD power supply and that the retroreflective target is small relative to the shaft circumference, ≤15º


기능

  • Works with CCLD, DeltaTron or ICP® inputs from 3 to 20 mA constant current
  • CCLD power means:
    • No separate power supply required
    • Simple two-wire cabling
  • Continuous wave laser for jitter-free order tracking and balancing applications
  • Operating range to at least 70 cm (27'')
  • Manual test button to verify tachometer trigger level when the machine is not rotating or available
  • Low sensitivity to background light
  • Robust and IP 64 rated
  • Flexible mounting options make it easy to attach:
    • ¼''–20 UNC (camera tripod), 10–32 UNF and M4 on the flat side of the probe
    • M22–1 threading with flange on the front

Powering

MM-0360 can be used with any DeltaTron or ICP® constant current line drive (CCLD) supply that provides 3mA to power the tacho probe.
MM-0360 is ideal for use with Brüel &Kjær data acquisition hardware:

Mounting

Use of the probe is very straightforward. Mount it in a convenient static location on or off the machine up to 70 cm from the target by using a magnetic mounting base such as the optional UA-0642 or a suitable bracket to connect to the M22–1 thread on the front of the probe. Alternatively, use a camera tripod with standard ¼''–20UNC (DIN 4503) thread.

The probe should be aimed so that its visible laser beam faces the test object to which a small strip of self-adhesive reflective tape has been attached. The retroreflective tape backscatters the laser energy to the receiver. Backscattering of the light means that the probe can be more than 30º from perpendicular to the measurement surface.

Output Signal

For each pass of the target, a negative 0.8Vp pulse is output, DC biased between +18.0V and +19.5V.

MM-0360 is capable of measuring down to 0RPM* when used with measurement system capable of DC coupling of the CCLD power supply such as in the Brüel&Kjær LAN-XI family of data acquisition hardware (bp2215.pdf).

It is possible to use MM-0360 with a standard DeltaTron or ICP® CCLD supply. The low RPM limit of the system will no longer be 0RPM, but instead will be the high-pass frequency of the CCLD power supply. Bias voltage and signal amplitude are almostcompletely unaffected...
