Several different detector designs exist for process gas chromatographs. The two most common are the flame ionization detector (FID) and the thermal conductivity detector (TCD). Other detector types include the flame photometric detector (FPD), photoionization detector (PID), nitrogenphosphorus detector (NPD), and electron capture detector (ECD).

Simplest Metal Detector Circuit. The simplest metal detector circuit consists of 4 components. The detectioncoil consists of 70 turns of wire 120mm diameter. Place an AM radio near the searchcoil and tune it to pick up a squeal. When a coin is placed near the coil, the tone will alter.
In radio, a detector is a device or circuit that extracts information from a modulated radio frequency current or voltage. The term dates from the first three decades of radio (). Unlike modern radio stations which transmit sound (an audio signal) on an uninterrupted carrier wave, early radio stations transmitted information by radiotelegraphy.
