REED DT-1236L Photo/Contact Tachometer with Laser

Mike — Fri, 15 Apr 2016 02:36:18 +0000

For difficult access, nothing beats the REED DT-1236L laser tachometer. This unit also measures linear speeds & contact RPM measurement. The non contact measurement can be made with reflective tape on the shaft, or white paint for close range. Contact measurements use a rubber cone (shaft centre drilling) or rubber rimmed wheels for linear speed. These components are replaceable separately. For fixed installations Lutron makes a panel mount 48×96 digital indicator for inductive or optical pickups.

REED DT-1236L Specifications

Trouble-shooting Procedures

Reflective Marking Tape To use this, simply cut the adhesive tape provided into approximately 12mm ( 0.5″) squares, peel off the backing and apply one square to each rotation shaft. The non-reflective area must always be greater than the reflective area. If the shaft is normally reflective, it must be covered with black tape or black paint before attaching the reflective tape. The shaft surface must be clean and smooth before applying the reflective tape.

Very Low RPM Measurements

When measuring very low RPM values, it is recommended to attach more reflective tape and take several readings. Divide up all the readings taken to come up with an average RPM measurement.
