NTRODUCTION The Proton Products SL mini and SLR mini series of laser speed and length gauges provide highly- accurate, non-contact speed and length measurement. SL mini series gauges offer speed and length measurement for unidirectional production lines. SLR mini series gauges offer speed and length measurement for bidirectional production lines. The gauge senses the direction of motion and will automatically increment or decrement the length accordingly.

The case temperature of the gauge can be viewed on the Status page 2 on CDI4.
NSTALLATION RECAUTIONS Operating and storage temperature Specification Minimum Typical Maximum Units Operating temperature ° C Storage temperature ° C • Do not store or operate the gauge in temperatures outside of the specified ranges. • Do not install the gauge near high temperature surfaces or objects which may cause it to overheat.
• For all class 3B laser devices, the safety measures below MUST be provided. Some measures are the responsibility of the device manufacturer (Proton Products), whilst other measures are the responsibility of the end-user. •...
• If the optical window appears to be damaged or misaligned, then the unit should be sent to a Proton Products authorised service agent for repair. • If the optical window requires cleaning, then refer to the cleaning procedure detailed below to minimise the risk of scratching the windows.
NSTALLATION SEQUENCE Unpack the gauge and check for missing accessories and shipping damage. Mechanical installation: 1. Mount the gauge securely either on a user supplied mount or on an optional Proton Products mounting plate. Electrical installation: 1. Install earth connections.
ECHANICAL NSTALLATION Stand-off distance and depth-of-field • For best accuracy, locate the measured object at the specified stand-off distance to the gauge. • Speed and length measurement is possible for objects located away from the specified stand- off distance but still within the depth-of-field; however the measurement accuracy may be degraded by the reduced signal strength.
Object stabilisation For accurate speed and length measurements, the distance between the measured object and the gauge must be kept constant; the measured object must be guided to prevent flutter: Incorrect Correct The end-user must provide suitable mechanisms for guiding and stabilising the motion of the measured object.
Optical alignment Non-perpendicular alignment of the speed and length gauge to the measured object will degrade measurement accuracy; it is recommended the gauge is installed and aligned by technicians with metrology experience who understand the implications of even a small angular misalignment. Correct Gauge Alignment Pitch alignment Acceptable for γ...

Measurement Direction SL mini Unidirectional Speed and Length Gauge The unidirectional SL mini speed and length gauge interprets motion in either direction as a positive speed and an increase in length, thus correct length accumulation requires that the object must only move in one direction (reverse motion will incorrectly cause the length to increment, not decrement).
