  • The Rate Integrating Gyroscope (RIG), Part 1
    The gyroscope is an instrument where the input is a rate of turn (angular rate). Any gyroscope is a torque-in, torque-out device. Therefore, the output of the gyro is a change in the gimbal angle (the gimbal turns) in response to the rate of turn input, due to gyroscopic precession. The input
  • US Dynamics Rate Gyroscope Interface Brief
    This applications note discusses in brief, the typical input signals to and output signals from a US Dynamics miniature spinning mass Rate Gyroscope. Since there are several variations of rate gyroscopes, the signals exemplified here represent those typical of the Model 475 Rate Gyroscope, a common
  • US Dynamics Model 475 Rate Gyroscope Technical Brief
    the reader to the basic rate gyroscope functionality. The rate gyroscope is a rate-of-turn transducer. The output signal represents the 'angular degrees per second' (a rate) of a turning maneuver. The output of a rate gyroscope is calibrated in 'millivolts (mV) per degree per second'. A typical rate
  • Reading Pulse Output Sensors with dataTaker DT8x Data Loggers
    Users often run into applications that require data logging from sensors that provide a pulse output. Common types of these pulse output sensors include flow meters, speed sensors, electrical power meters and switches for event counting. These applications may require the measurement of a rate
  • Basic Output Generator Excitation and Demodulation Requirements for USD Gyroscopes
    This applications note discusses the input signal excitation and output signal conditioning (demodulation) requirements of the transformer type output generator, or pickoff used on the US Dynamics Miniature Rate Integrating Gyroscopes (RIG) and Rate Gyroscopes. In addition, basic transformer type
  • Model-Based Inferential Sensing of Melt Flow Rate in Polymer Compounding Operations (.pdf)
    In plastics compounding operations, product melt flow rate (MFR) is frequently one of the quality control variables and it is usually measured off-line in a quality control lab using an extrusion plastometer. The ability to monitor product MFR on-line from output process variables such as motor
  • Bulk Bag Filling Rate Guide
    Every filling machine requires an operator to physically rig the bulk bag, initiate the fill sequence, tie-off the filled bag, and to initiate bag removal. Some filling machine models, however, lend themselves more readily than others to automation. The output of filled bulk bags from the selected
  • Pressure Transducer Usage in VFD Control for Electric Motors in Machinery and Factory Automation
    VFDs, or variable frequency drives, are a common tool in electric motor control. VFDs, simply put, control electric motors by modifying the power input frequency to the electric motor. VFDs used in conjunction with electrically driven pumps can be made to control both the flow rate and the output
  • Wireless InSite 2.4 New Features List
    A Communication System is now available for performing interference analysis using selected transmitter and receiver sets. The result of this calculation is bit-error rate output files that appear in the output tree under the communication systems entry in each active study area. This analysis
  • Lean Opportunities in MRO Procurement
    Productivity is output, efficiency, and production. In economic terms, it is the rate at which a company produces goods or services in relation to a needed amount of materials and employees. Productivity can be defined in two ways: 1) Total labor productivity is simply output divided by the number
  • Melt Pressure Measurement: Environmental Effects
    The Need For Pressure Measurement in Extrusion In order to maintain the dimensional stability necessary to produce extruded products that meet todays precise quality and tolerance specifications, it is necessary to keep both the output rate and the melt condition constant (1,2). Although
  • Fan curves and optimum operating points
    Fans create a flow of air, which they can then force through equipment that needs cooling. The necessary output is determined from the flow rate and the required static pressure. If the airflow through the equipment is restricted to any great extent by built-in components or bends and junctions
  • AN126 Tuning Surge Tank Level Control Loops
    A surge tank is placed between two processing units (Figure 1) to absorb flow rate fluctuations coming from the upstream process so that the flow rate to the downstream process changes less rapidly. To do this, the tank level has to go up and down. Consequently, the level controller should not try
