STI-94 Pulse Rate/ Period Meter

Introducing the STI-94 Tachometers: Versatile Speed and Frequency Measurement Devices

Control the speed of rotational or linear motion with precision using our STI-94 Tachometers. These cutting-edge devices are not only capable of accurately measuring frequency but also offer additional advantages. Convert rotational or linear speed into inverse values effortlessly, and conveniently display single revolution periods or process durations.

Customise your experience with programmable REL/OC control outputs that respond to instantaneous rotational speed values. Choose from a range of analogue outputs to suit your needs: active current output, passive isolated current output, or active voltage output.

Configuring the counter is a breeze, thanks to the user-friendly local keyboard or our S-Config software via the RS-485 communication port. Experience enhanced speed control and measurement capabilities with the STI-94 Tachometers.

Product Highlights

The STI94 tachometers are highly versatile devices designed to effectively control and monitor the rotational or linear speed of moving objects. With its ability to accurately measure frequency, this tachometer offers precise data on the speed of various processes. A notable feature of the STI94 is its capability to convert rotational or linear speed into inverse values, providing valuable insights into single revolution periods or process durations. Moreover, the device offers flexible control outputs such as REL/OC, which can be programmed based on the instantaneous value of rotational speed. For enhanced customisation, the counter can be equipped with analogue outputs tailored to the customer’s needs, including active current output, passive isolated current output, or active voltage output. Configuration options are made convenient with either the local keyboard or the user-friendly S-Config software, accessible via the RS-485 communication port. The STI94 tachometer stands as a reliable and adaptable tool for precise speed control and measurement in a wide range of applications.
