    Current Measurement Device

    Thanks Lewish, By remote, I mean it needs to be stand-alone... I can't be there to hold it or position it. It needs to be something (non-hand held) that I can affix to a cable to read the current going through it, and, it needs to send out a signal that a simple datalogger can read (like, say...

    Current Measurement Device

    Hello, I am looking for two current measuring devices. They both need to be remote (non-handheld), and send out a signal (such as analoge voltage) that can be interpreted by a data logger, for transmission into a PC. The first needs to measure the current being drawn by a 24V DC Motor...

    Motor RPM Measurements

    Thanks Pete... That would be an option.. but the application will be remote (at the bottom of the ocean, actually), so I won't be able to take the readings myself. What I'd like is a device that sends me some form of signal (analogue or ditial). Then I could enter this signal, among others...

    Motor RPM Measurements

    I need to measure the RPM of the output shaft of my motor. I was thinking of using an incremental encoder, or some kind of tachometer. I'm looking for the most cost effective solution. What are my options in terms of RPM Measurement? Can anyone out there help me? Thanks, AAR

    DC vs. Stepper Motors

    I want to compare and contrast a DC Motor and a Stepper Motor. What are their primary uses, advantages, and disadvantages. The application I am looking at involves a drive system which is to provide a (relatively) constant torque of 10 N.m over it's range of opertion (0-50rpm output from a...
