Standard North American installation of a combination hot box / dragging equipment detector A defect detector is a device used on railroads to detect axle and signal problems in passing trains . The detectors are normally integrated into the tracks and often include sensors to detect several different kinds of problems that could occur.
A remote terminal unit (RTU) is a microprocessor-controlled electronic device that interfaces objects in the physical world to a distributed control system or SCADA (supervisory control and data acquisition) system by transmitting telemetry data to a master system, and by using messages from the master supervisory system to control connected objects.

In some transducers, signal conditioning is integrated with the sensor, for example in Hall effect sensors. In power electronics , before processing the input sensed signals by sensors like voltage sensor and current sensor, signal conditioning scales signals to level acceptable to the microprocessor.
A string potentiometer is a transducer used to detect and measure linear position and velocity using a flexible cable and spring-loaded spool. Other common names include string pot, cable-extension transducer, draw wire sensor, and yo-yo sensor.
Reception problems related to ship noise were partially solved when A. J. Munday, who had worked with Dr. Elisha Gray on signaling by underwater bells to include actual messages, found that a microphone placed in a metal box filled with water and attached to a ship's skin from inside allowed clear reception. In further experiments placement of ...

An electret film is applied to the back plate of the microphone capsule and the diaphragm is made of an uncharged material, which may be mechanically more suitable for the transducer design being realized. Front electret This design features no back plate, and the capacitor is formed by the diaphragm and the inside surface of the capsule.
