An ultra-fast measurement and ultra-precise transducer specifically developed for Machine Tool Monitoring applications. The PWM3120T is a unique design based on the fastest available 32-bit Microcontroller and 18-bit successive approximation AD Converters. A sampling rate of 150kHz ensures precise and correct measurement even when used with Frequency Inverters with 20kHz PWM base frequencies and higher.
PWM3120T measures true motor power [kW].
