An ultra-fast and precise measurement transducer specifically developed for Machine Tool Monitoring applications. The PWM3110T is a unique design based on the fastest available 32 bit Microcontroller and 18 bit successive approximation AD Converters. A sampling rate of 150kHz ensure precise and correct measurement even when used with Frequency Inverters with 20kHz PWM base frequencies and higher.
PWM3110T measures true motor power [kW].

· The PWM3110T is designed primarily for measuring AC power delivered to motors driven by Variable Frequency Inverters.
AC power is measured from the formula:
Where: T = period, V (t) = voltage and I(t) = current.
· The PWM3110T Power or Current Transducer is specifically developed to function as a load transducer for the TECHNA-CHECK® Range of Machine Tool Monitors.
· A Power Transducer for Tool-Monitoring must be fast and accurate. Sometime the measurement speed is as high as one half period, unlike commercial power-meters, which measure power averaged over several seconds.
· Please note that most commercial Power Meters will not even be able to measure Power correctly after a Variable Frequency Inverter. The transducer interfaces to Tool Monitor Applications via the proprietary TTBus interface.
· The three motor wires must pass through the external hall sensors in the same direction to the motor either from Top- Bottom or from Bottom-Up.
