TM-801 Digital Panel Mount Tachometer with Digital Tachogenerator Sensor

Model Number – TM-801

It is designed for panel mounting, making it easy to install and use in industrial environments. The digital tachogenerator sensor measures shaft rotation, and the digital display displays the speed in revolutions per minute (RPM). This type of tachometer is ideal for applications such as motor speed control, fan speed control, monitoring conveyor belt speeds, and more. It is also suitable for use in hazardous conditions, as it is designed to be explosion-proof.

Key Features

Used in industrial applications to monitor the performance of motors.

  • Full Digital, Micro Controller LSI circuit design with Auto Ranging, Crystal controlled time base.
  • Useful for measurements of RPMs of motors, mixtures, pumps and other rotary devices. With excellent quality, compact size and accurate reading.


Working Principle

Employs the principle of generating digital pulse output using Opto-interrupter & a rotating coded disc. This digital signal output of 60 PPR (TTL-compatible) proportional to speed is digitally processed and computed & RPM is displayed on panel meter

Digital Tachogenerator

The Tachogenerators/optical encoders consists of aluminum casting housing with S. S. shaft which has to be coupled with the rotating shaft of drive whose rpm is to be tested/measured continuously.
Tachogenerator is of face mounting type with 65 mm diameter Housing, 10 mm dia. S.S. shaft
