World's First All-Digital Metal Detectors. VFLEX transforms conventional single frequency metal detection technology by including two microcontrollers (miniature computers), one inside the control box and one inside the coil. Every time the detector starts up, the microcontrollers establish communication via a digital data link.

TDA0161 3 Operating Mode 5/12 3 Operating Mode Between pins 3 and 7, the integrated circuit acts like a negative resistor with a value equal to that of the external resistor R1 (connected between pins 2 and 4). The oscillation stops when the tuned circuit loss resistance (Rp) becomes smaller than R1. As a result, I CC(close) = 10mA (pins 1 and 6).

TDA0161 Proximity Detector IC- This IC is a proximity detector. This IC suplies the oscillating signal that is sent through the LC parallel circuit. The IC also responds to any changes in the signal. The IC has an output of 1 milliamperes (mA) or less if the coil is far from a metallic object and an output of 0mA or higher if the coil is near a metallic object.

TDA0161 metal detector electronic schematic. To adjust the circuit you need to make sure there is no metal near the coil and then set the fine adjustment to a "Mid position". After that you need to adjust the course adjustment to turn on the LED and, adjust the fine adjustment to turn off the LED. This detector electronic circuit operates over a wide range input voltage of 4 -35 volts ...

A metal detector is an electronic instrument that detects the presence of metal nearby. Metal detectors are useful for finding metal inclusions hidden within objects, or metal objects buried underground. They often consist of a handheld unit with a sensor probe which can be swept over the ground or other objects.
