What are the benefits of converting pulse signals (frequency) from sensors to CAN?

Converting to digital transmission (CAN) makes signals far less susceptible to external noise, preventing signal loss or waveform distortion even over long distances. Bus wiring significantly reduces installation labor, and utilizing automotive protocols like SAE J1939 simplifies data integration into existing control networks.

What are the strengths of measurement using the Periomatic calculation method?

Our proprietary calculation algorithm achieves high accuracy and fast response across the entire range from ultra-low speeds (600 μHz) to high speeds (1 MHz). It instantaneously tracks sudden speed changes and rapid stops, making it ideal for dynamic motor evaluation and precision speed control such as film winding.

What input signal formats and adjustment features are supported?

It supports various signal formats including 5V/12V logic, zero-cross, NPN open collector, and line driver. It also features trigger level adjustment (0 to 9.99 V), hysteresis, and low-pass filter settings, allowing optimal tuning suited to on-site sensors and noise environments.

Is there a convenient model for on-site operation checks and temporary measurement?

We offer the handheld 'SPD-HD'. It can operate on battery power, allowing users to carry it to check and log sensor signals on-site. Featuring simultaneous 16-bit analog and CAN outputs (1 ms), it is extremely convenient for equipment inspection and temporary data collection.
