SpeedSys® T11 speed transmitter, monitor & switch SpeedSys T11 Speed transmitter, monitor & switch. The SpeedSys T11 is a speed measurement system, part of the SpeedSys tachometer series. monitoring functions for rotating equipment. The T11 converts the signal from a speed sensor into a processed output and is equipped with a display that shows the rotational speed. Enclosed in an industrial panel mount housing, it is designed for seamless integration in industrial environments. SPEED MONITORING FOR A WIDE RANGE OF APPLICATIONS ▪ ▪ Speed monitoring and switching on rotating Typical applications include: Advanced signal conditioning and conversion into highly accurate outputs for further processing Wind turbines Marine applications General automation Fast system response to overspeed events One high speed relay Modbus connectivity Suitable for 3-wire voltage sensors and 2-wire voltage sensors
