Field-programmable Frequency Transmitter

At our factory, we are having a problem with a motor, which occurs at the time of a certain number of revolutions. To monitoring, we like to count the number of revolutions by pulse (frequency) and convert to 0 to 10V DC to input to the recorder. The motor is running 0 to 1,000Hz, and the problem occurs in the range of 820 to 890Hz. I know that the input frequency is from 0Hz with a standard frequency transmitter. But, to check a problem in detail, we like to have a module which can be configured 800 to 900Hz as 0 to 100% output. Is there a product?

We propose a field-programmable frequency transmitter (Model: MXPA). MXPA is easy to programmable via front UP-DOWN keys with a help of 4-digit and 2-digit displays. Input frequency range is programmable so 0% input frequency range is selectable. In this case, please set up Input frequency range (Item 07) as 5: 0-1KHz and 0% Input frequency as “0.800” and 100% input frequency as “0.900”. By doing this setting, Input frequency 800 to 900Hz becomes 0 to 100% output as 0 to 10V DC. For recording, we like to introduce a 73VR2102 Paperless recorder.
