  • Utilizing the Power Shutdown Capabilities of the Kionix Tri-Axis Accelerometers (.pdf)
    ) and Maximum Sampling Rate (Hz), Ton (ms), Duty-Cycle (%). Microprocessor Controlled Power Reduction System. When the Kionix accelerometer is hooked up to a microprocessor, such as the Texas. Instruments MSP430F149, a 10% duty-cycle, power shutdown toggled system can. be easily implemented. This power-reduced
  • Thermographic Monitoring of Refractory Lined Petroleum Refinery Equipment
    , carried out the thermographic. surveys. The monitoring program was devised and controlled by one of the refiner's inspection engineers,. who is ITC Level II certified. SURVEY RESULTS. Surface Temperature Measurements. The results of the temperature measurement were recorded every two weeks
  • Interfacing Microchip's Fan Speed Controllers to a SPITM
    , significantly extending fan life. In addition to increased fan life, fan speed is controlled by PWM control circuitry that is more efficient than conventional linear techniques. The ICs provide other features such as fan current limiting, minimum speed control, auto shutdown, and speed, fault
  • The Value of Reliability: How Smart Advisor Avoids Equipment Disruptions
    Maintenance is a key technology for insuring high reliability of. critical plant equipment. These on-line systems detect upcoming failures of critical plant. assets, allowing for a planned, controlled shutdown, and replacement of faulty. components. On-line Condition Based Maintenance results
  • Methods To Increase The Hold-Up Time Of AC/DC Or DC/DC Converters
    signal when the supply voltage is turned off (T4). After the processor receives a power failed interrupt signal, it will go through its shutdown routine that may include collecting critical data, such as turning off controlled transducers, etc. ./bf32dcef-db8d-4b69-9ab9-353b51c30c8c beta
  • Scanning for Ideas: A Motor Pump Built for Solar Power
    voltage-current curve to get maximum performance. This coincides with the point at which the pump generates maximum rpm and, therefore, maximum performance. The electronically controlled motor operates on 8 to 24 Vdc. The pump can generate up to 250 psi with a brass housing, or 50 psi with the plastic
  • Simpler controls lead to lower-cost pneumatics
    and reducing diagnostic and troubleshooting times. And fewer potential failure points increase system and device reliability. DeviceLogix can also offer safe-shutdown sequencing, the ability for an internal parameter to be set up that detects network failure and initiates a controlled shutdown or other
  • Regeneration vs. Dynamic Braking in DC Drives
    are in a DC phase controlled drive. Regeneration in a phase controlled DC drive involves a second (antiparellel connected) rectifier bridge. During regeneration, mechanical energy from the rotating load and armature (now acting as a generator), is inverted from DC directly back onto the AC power line
