Magnetic Sensor Symbol

Symbols of electronic sensors transducers detectors.

Magnetic sensor symbol. Symbols of electronic sensors transducers. The contacts are usually normally open closing when a magnetic field is present or they may be. Jic nfpa sample drawing. Only spectra symbol s magnetopot.

As a level sensor both liquid level sensor and a magnetic potentiometer the magnetopot will give linear feedback to position. Proximity sensors symbols for use in electrical pneumatic and hydraulic schematic diagrams. Compensation for temperature effects is necessary. A hall effect sensor or simply hall sensor is a device to measure the magnitude of a magnetic field its output voltage is directly proportional to the magnetic field strength through it.

A mems based magnetic field sensor is a small scale microelectromechanical mems device for detecting and measuring magnetic fields many of these operate by detecting effects of the lorentz force. Hall effect sensors are used for proximity sensing positioning speed detection and current sensing applications. The reed switch is an electrical switch operated by an applied magnetic field it was invented at bell telephone laboratories in 1936 by walter b. A change in voltage or resonant frequency may be measured electronically or a mechanical displacement may be measured optically.

For liquid level sensors the magnetopot can attach to the outside of a liquid tank and give position of the magnet inside the float. In its simplest and most common form it consists of a pair of ferromagnetic flexible metal contacts in a hermetically sealed glass envelope.
