Category: Sensors Detectors / Sensor Circuits Views: 3532 Rank: 0 Anyone performing their own automobile tune-ups knows how important it is to know your engines speed. With this tachometer, you can measure your engines speed without any connections or annoying timing lights. visit page.
Related circuits This circuit detects the 1050-Hz tone sent by the NOAA (National Oceanic and Atmospheric Administration) Weather This circuit is useful for signal-processing sonar data recorded on an instrumentation-quality analog tape recorder. The envelope detector utilizes ready available parts, and furnishes accuracy beyond 100 kHz. Two LM301 op amps connected as precision absolute-value circuits use 2-pole frequency... I designed this circuit as a simple current indicator for any load ranging from 40 watts to 250 watts. The circuit turns on a small LED, whenever it detects current flowing to a remote load. Closed-Loop Peak Detector Circuit This closed-loop peak detector circuit uses a Schottky diode inside feedback loop to obtain good accuracy. The 20- resistance RQ isolates the 0.01- load and prevents oscillation. The dc value is read with a DVM. At a low frequency, the error is small and dominated by the decay of the detector... Accelerometer Scale Factor and Offset Adjustments The ADXL50 and ADXL05 accelerometers are small, low cost, easy to use devices. These modern integrated circuits have an onboard buffer amplifier that allows the user to change the output scale factor and 0 g bias level. MACHINE VIBRATION TRIGGERS HOUR METER This circuit allows an off-the-shelf battery powered digital hour meter to be turned on and off, according to a machine`s operation, without requiring a direct electrical connection to the machine. Machine vibrations are detected by an off-the-shelf piezoelectric wafer. The wafer is normally used... RS-232C link monitors animal activity A common need in biological experimentation is the ability to unobtrusively monitor the activity of small caged animals, such as mice, rats, and rabbits, as they move about their enclosures. This monitoring must be over long periods and around the clock. The circuit in Figure 1 allows you to... Simple Full-Wave Envelope Detector Circuit Simple, yet sensitive, this amplifying full-wave detector circuit has an almost zero rectification threshold. It presents a highly linear RF load to the final IF stage. Dixson Model 1082 Wireless Tachometer for small engines
