  • Should You Use Current or Voltage in Analog Transducer Readings?
    Several instrumentation monitoring applications including equipment monitoring, quality assurance and others require you to choose among the different signal types for your analog measurement transducer. The most common of these are either voltage (0-5 volts DC, or 0-10 volts DC) or current
  • What is an I-to-P transducer?
    A transducer is any device that converts a signal in one form of energy to another form of energy. The device is referred to as I-to-P (or I/P) because it converts an electrical "current" input signal to a "pressure" output. The symbol "I" is used to represent current because current was originally
  • Understanding Current Sinking, Current Sourcing, and Ground Loops
    You've just purchased some current to pneumatic transducers and are ready to try them. Each transducer has been carefully installed according to the manufacturer's recommendations and wired to its own 4-20 mA analog output. All of the transducers are being powered by a common 24 VDC power supply
  • Use of a Single Element Wattmeter or Watt Transducer on a Balanced Three-Phase Three Wire Load Will Not Work - Here's Why
    Frequently customers wish to save money bymonitoring a three-phase, three-wire connected motor with a single element (one multiplier) watt (power) transducer. This will not work. The voltage as measured from line to line in a three-phase circuit is 30º out of phase with the current as measured
  • Understanding the Importance of Transducer Orientation
    When monitoring vibration on large gas or steam turbines and generators with fluid-film bearings, the relative movement of the shaft within the bearing is typically measured by a pair of shaft proximity (eddy current) transducers. Data from these transducers is used to produce a variety of plots
  • BRL Calibration Procedures for Ballistic Pressure Transducer (.pdf)
    Current procedures used for the calibration of ballistic pressure tranducers at BRL are described. Checks include evaluation of continuity, hysteresis, and zero return characteristics as well as calibration against a dead weight system.
  • When did the Alarm in My IUV Go to Harvard?
    In 1968, the first true electronic alarm was offered to the market and engineers and system designers. grasped pretty quickly that these alarms were a major advance over the current state-of-the-art electromechanical. alarms. The new alarm technology utilized a piezoelectric transducer and solid
  • Frequency Control Air Compressor Solution (.pdf)
    electricity. All of these request sequential operation of corresponding switches, valves and control transducers. When operating, check air compressor conditions frequently. In case of temperature, pressure or motor rated current exceeding limits, stop running immediately. If pressure is high
