Welcome toArabianSea(Marine Electronics and Instruments)Product Name:Prisma Teknik Crankshaft Deflection Indicator Di-4. Made in Sweden. Product Brand:Product Condition :UsedProduct Condition :Tested ok. Check Pictures. Product Inclusion :What you see is what you get unless otherwise specified. Description/Features/Specifications :Prisma Teknik A/B are manufacturers of deflection indicators. It is necessary, and important, to regularly measure crankshaft alignment in large diesel engines. In the past, engineers have used a clock-dial indicator gauge. This method was time consuming, often inaccurate and unpleasant. These circumstances lead to irregular checks which could cause expensive, major breakdowns. Now these checks can be done quickly and safely using the Deflection Indicator DI-4.The DI-4 consists of a transducer with various extension bars and a battery operated digital instrument. It is stored in a strong wooden case for safe keeping.Deflection Indicator DI-4 (crankshaft deflection analyser)Large measuring range from +1,999mm to -1,999mm for deflection makes it possible to move the transducer from cylinder to cylinder without mechanical adjustment. Extension bars made of Invar alloy with minimal expansion, much less than steel. Optional bars can be ordered if needed. Battery operated - 150 hours of service on a set of batteries. Easy zero balancing by push button will cover +0,500mm to -0,500mm transducer offset. LED Back light function. Automatic switch-off after 2 hours eliminating the risk of draining batteries. An arrow indicates low battery but allows time to finish the measurement.Technical InformationMeasuring Range+1.999mm > -1.999mmZero Balance Range+0.500mm < -0.500mmResolution0.001mmZero Drift0.001mm/5 minsOperating Range0-55°C 32-130°FTransducer Range0-80°C 32-175°FBatteries3 x 1.5V R14 alkaline ( Not Included )==================================Terms of Sale We ship using DHL, Fedex or India-Post.Payment using Paypal.
