Signal tracer Signal tracer A signal tracer is a piece of electronic test equipment used to troubleshoot radio and other electronic circuitry. Usually a very simple device, it normally provides an amplifier, and a loudspeaker, often battery-powered and packaged into a small, hand-held test probe. An optional diode detector is usually also provided, allowing the detection of amplitude-modulated signals. The technician injects a test signal into the device under test. Then, by using the signal tracer, the tech can follow the signal through the various circuits of the radio receiver. So long as the signal can be heard, the circuitry up to
Presence sensing device safety of a press brake operator while employing the precision of lasers directly surrounding the die. OSHA's caveat to its approval of the device was that they be properly installed and inspected. Among other presence sensing devices available, this device can be used as a retrofit to aging machines. Cameras are another electronic safety device used for press brake safety. The camera can detect an intrusion between the upper and lower dies. If an intrusion is detected, a signal will stop the downward movement of the ram. A camera safety system uses a linear scale to calculate the upper beam's
