Remote Optical Laser Sensor

The Remote Optical Laser Sensor has a visible red laser lightsource and green

LED on-target indicator. The class 2 laser source acts as theaiming device during

setup and can accurately measure speeds from 1-250,000 RPM froma distance of

up to 25 feet with a maximum offset angle of 60 degrees from therotating object.

The sensor is housed in a threaded 303 stainless steel tube andsupplied with a 90

Complies with FDA performance standards for laser productsexcept for deviations pursuant to Laser

Notice No. 50, dated July 26, 2001.

The ROLS Remote Optical Laser Sensor is capable of detecting areflected pulse from a target consisting of T-5 Reflective Tape or high contrast

color differences (such as black and white) at distances up to25 feet [7.6 m] from the rotating object and angles up to 60 degrees. For most

applications, a å?åÓ [12 mm] square piece of Reflective Tape(T-5) should be applied to a clean area on the rotating object. At slow speeds(<500

RPM) best results will be obtained by aiming the laserperpendicular (90°) to the target using a narrow piece of reflective tape åÐtypically 0.2 inch

(5 mm) wide.

The ROLS should be mounted (using the supplied jam nuts andaluminum mounting bracket) and optically aligned to illuminate the on-target

indicator once per revolution. It is recommended that theoptical sensor be placed at a slight angle (15 degrees) from perpendicular, sothat the

sensor will receive only pulses from the reflective marker.Triggering from contrasting colors should be done perpendicular to the target.The

ROLS should be at least 1 inch from the reflective target toavoid false triggering. The green LED On-Target Indicator will blink at theinput

steady at high speeds.

The ROLS is supplied with a 3.5 mm [1/8 inch] male stereo plug (ROLS-P)or an 8 foot [2.4 m] cable terminated with 4 tinned wires (ROLS-W).

The plug may be cut from the cable and the leads stripped andconnected as shown in connection detail for tinned wire above. An optional 25foot

[7.6 mm] extension cable EC-25P is available with a femalesocket for the plug on one end, and a 3.5 mm [1/8 inch] male stereo plug on theother

(for ROLS-P).

The ROLS-P will work directly with all Monarch handheldtachometers and Nova-Strobe dax, dbx, and pbx Stroboscopes. The ROLS-W will work

with all Monarch panel instruments that accept pulse inputs(e.g. ACT Series, DataChart 1250, DataChart 6000) and vibration data collectors.A

sensor power supply (SPSR-IM) with BNC output is available forthose applications that require a separate power source for the sensor.
