10.5 Power Module

The power module for IQ Pro and IQT Pro actuators produces internal power supplies for control systems and remote control derived from the actuator electrical supply. It also contains the motor control and switching components.

10.6 Torque Sensor 10.7 Position Sensor

State of the art piezo thrust sensor measures motor shaft thrust produced as a reaction to output torque developed in the motor worm and wheel gear assembly. Thrust measured is directly proportional to output torque. The piezo sensor develops a voltage proportional to shaft thrust (output torque) which is amplified and then measured by the control module. Output torque is controlled by switching the motor off when the set torque limits have been reached. This system allows the torque to be displayed via the LCD display and captured by the datalogger in the form of valve torque profiles, statistical torque information and the event log. Contact-less hall effect sensors measure actuator output shaft angular rotation to a resolution of 7.5° (15° max for reversal). Sensors are direction sensitive producing a phased digital pulse width modulated signal. The control module counts the pulses and compares these to the set limit range. Precise position control is then available for limit switching, position indication and data logging. The position sensor is very simple with only one moving component and has a proven, reliable track record in use with IQ actuators for over 15 years.
