1. Running Peak Torque and Fluctuating Peak Peak Torque The user can optionally display the Fluctuating RMS Torque Torque Definitions The Torque Transmitter Receiver has a frequency response of 1000Hz The computer and A to D converter in the Monitor have a frequency response of about 400Hz Todo the best job of obtaining all data of possible interest the Monitor includes analog circuitry to do averaging peak detection and provide the RMS valued of the fluctuating torque The signal from the Transmitter Receiver will be considered the instantaneous torque as its frequency response is relatively high compared to typical machine operating speeds and possible torque anomalies Average Torque The instantaneous torque is filtered to provide an average value that is measured and displayed by the Monitor Peak Torque The instantaneous torque goes to a peak detector with a slow bleed off The output is measured and the computer keeps track of the highest value DOC1072 Rev 2 1 Page 2 Riverhawk Company ANE 4100 Users Manual measured since the last reset When the value is reset it will be set to next instantaneous value and increased as appropriate Running Peak Torque The instantaneous torque goes to a peak detector with a slow bleed off The output is measured and the computer keeps track of the highest value measured during the last 60 seconds Therefore that is a moving window peak detector2. Fluctuating Peak Peak Torque The minimum and maximum values of instantaneous torque are determined on a second by second basis The minimum value is subtracted from the maximum value to yield a peak to peak value This provides an indication of the spikes in the torsional vibration Fluctuating RMS Torque The instantaneous torque is AC coupled to an RMS measuring device and output is filtered and measured This provides an indication of the energy in the torsional vibration 2 Wiring Cable cord grips are provided for the receiver As the Monitor is rack mounted the customer is responsible for all cable protection and fittings as required Standard PVC jacketed cable is provided for connecting the Receiver to the Monitor Two cables run between the Torque Speed Receiver and the Processor one for 12VDC power and one for analog signal wiring These may be pre wired for ease of installation The Monitor is provided with a plug in line cord A second pluggable connector is provided for user connection of the two 4 20mA outputs A Dynamic Output BNC connector is provided for monitoring the instantaneous torque This is not a calibrated output Digital inputs and relay outputs may also be provided for future capabilities An RS 232 Software Update Port is provided for loading revised software if needed An RS 232 Configuration Port is provided for accessing real time and configuration information 3 Normal Operation
