Laser Tachometer

Mile High_PumpFE ·
Can anyone recommend a good tachometer for use with my vibe analyzer? I have seen in classes and in the field where other people have laser tachometer's that mount onto tri-pods that will function even up to 3 or 4 feet away from the rotating shaft, but I have yet to be able to find out who makes them. I use (see picture) a laser tach that I bought from The Modal Shop and I mount it to a magnetic dial indicator base. The problem is that it is VERY sensitive to vibration of the indicator...

I'm not the motor specialist but I guess it's false. NEMA MG1 standard should help in this kind of details. Max allowable temperature is different from maximum allowable temperature rise. Regards- Ali M. Al-Shurafa

115 degrees is correct. However, that refers to the windings inside the motor, the surface will be much cooler. 20 to 30 degrees cooler is generally accepted.

115C is specified in NEMA MG-1 as the maximum temperature rise for a continuous duty motor with service factor 1.15 or higher, in a 40C ambient. You might roughly interpret this to indicate that the insulation temperature limit is 115+40 = 155C at the service factor load. It's not quite that simple/exact. For lower service factor, the max rise would be 110C at full load. Also the associated temperature measurement is generally considered an average temperature if temperature is measured by...

Its seems this is truly one of the cases mentioned. Thank you. At the place where I work, it is a bit hotter than other places. For this reason, the ambient is not 40 C, as an exception. Orders are supplied with 50 C modification to the default standard paragraph. Regards- Ali M. Al-Shurafa

It seems to me that instead of replacing the laser, you should be exploring alternatives to the "magnetic dial indicator base." Are you using something like the one shown on the left, or a much more "stiffer" version as shown on the right.

Hi John, I actually use the most stiff one which the right side picture you posted. Our R&D lab also uses the same tach and indicator base setup, and they seem to have the same issue as well (that i do). Thanks, KB

A reliable source in the States is Monarch Instruments. Some of their offerings are at https://monarchinstrument.com/...chometer-accessories and many offer extended distance. The ROLS-Remote Optical Laser Sensor P/N 6180-029 will supposedly operate at 25 feet. I personally don;t have any experience at that type of distance, but have used a Monarch tach at something around 10 feet. Note that I believe that what the Modal Shop offers is actually made by Monarch. At least that was the case...

Here is company that sells Monarch products: https://www.reliabilitydirects...ter-Sensors-s/44.htm I believe several (not me) folks use this laser tachometer meter (ac signal output) with success: https://www.reliabilitydirects.../mon-6125-010-op.htm I have used Monarch remote optical and infrared sensors for a long time.
