Twin Digital Tachometer TSM-200
[Contact Us]
The ATSENSE TSM-200 Tachometer is a high-function twin digital panel meter designed for precise engine R&D, industrial machinery, and plant monitoring.
Supporting dual sensor inputs (A/B), it measures and displays both simultaneously with A+B, A-B, or average speed calculations.
With a 2MHz max input frequency, 0.5ms response, and multiple outputs (analog, CAN, USB, RS232/485, BCD, relay), it delivers fast, reliable, and flexible performance. Its IP66-protected panel and bright dual LCD ensure durability and visibility, making it ideal for demanding test environments.
Features
A high-precision, highly-functional digital panel meter with built-in tachometer measuring capability.
- The first panel meter that has been used for CAN data output (option) and flow auto-repeat measurement (flow meter)
- 6-digit and 13-digit, two-level, high brightness LCD display (red and green). You can choose the display color.
- A multitude of options (analog output/BCD output/CAN output/contact output/RS232 communication/RS485 communication/USB communication)
Introduction to Functions
- Both sensors (A, B) can be measured at the same time, and the display and analog signal for each can be output as desired
- Also A+B, A-B, and average speed measurement possible
- Maximum input frequency 2MHz (for single-phase), 500kHz for two-phase input
- Possible maximum response speed of 0.5ms for high-speed output, analog output, BCD output, and CAN output
The model configuration for this instrument is as shown in the figure below.
The model is left-justified when option “No” was selected.
Multiple options cannot be chosen from options in the same group.
Two different types can be selected out of digital output, contact output, and communication.
