SPECIAL APPLICATIONs682 series - saw tension gauge7793 series - pocket lasertachometer kit with caseThe Pocket Laser Tachometer is a digital,battery operated portable optical tachometerthat can operate up to 25 feet from a reflectivetarget using a laser light source.The powerful 32 function Tachometer/Ratemeter, Totaliser/Counter and Timeris programmable in both inch and metricrates. It has TTL compatible pulse outputto trigger devices such as data collectors orstroboscopes.Ergonomic design makes measurement ofspeed and RPM simple.The Starrett Saw Tension Gauge will checkfor proper blade tension in either English ormetric and is graduated both in pounds andkilograms.The tension gauge can be read directlyon either band saws of any type, or powerhacksaws.It is graduated to read up to 60,000 PSIor 4,000kg per cm 2 and is furnished withinstructions, including suggested tensions.Cat No Description Item No682EMZ Saw Tension Gauge DK037Cat NoRange Accuracy ItemNoOptical (RPM) Contact (RPM) Optical ContactS7793Z 5 to 200,000 0.5 to 20,000 ±0.01% of Reading ±0.05% of Reading DM595668 series - shaft alignmentclamp sets696 series - crankshaft distortiondial/strain gaugeABFGCDES668 mounted on coupling.An ideal gauge for checking bearingalignment or shaft deflection withoutdismantling the engine. Also useful as astrain gauge on engine frames. This insidemeasuring gauge checks the distortion ofcrankshafts webs. This distortion bears adirect relation to existing misalignment orexcessive bearing wear. The gauge makesit possible to check bearing alignment orundue shaft deflection without dismantlingthe engine. Used on all diesel engine shaftsand the centre crankshafts on any type ofengine or compressor, the gauge can also beapplied as a strain gauge on engine frameswhile the engine is operating.A comparison of readings taken at top andbottom positions indicates any misalignmentof cylinder and frame which results in localover-stress and eventual cracking of theframe neck.A special spring tension in the dial indicator,the gauge is self-sustaining in any positionwithout sacrificing necessary rigidity, thusleaving the operators hands free. The contactpoints are conical, with an approximate 60°included angle, hardened and ground toa sharp point, and will stay in place on 45°surfaces.Cat No Range Graduation Item No696MZ 61 - 458mm 0.02mm DK147The Starrett Shaft Alignment Clamp isdesigned for fast, precise alignment ofmotors, pumps, compressors, etc. Thissystem is capable of addressing radial andangular misalignment problems and can beset up within minutes.Products in photo (Cat No.): A.
