sensors are related to Electric current, electric potential, magnetic, radio. A current sensor is a device that detects electric current (AC or DC) in a wire, and generates a signal proportional to it. It can be utilized on display the measured current in an ammeter.

METAL DETECTORA current sensor is a device that
detects electric current (AC or DC) in a wire,
and generates a signal proportional to it. It
can be utilized on display the measured
current in an ammeter.
SENSORDaly detectors are typically used
in mass spectrometers. It also allows to use a
higher acceleration after the field-free region of
a time-of-flight mass spectrometer flight tube,
which can improve the sensitivity for heavy ions.
spectrometersElectroscopes detect electric charge
by the motion of a test object due to
the Coulomb electrostatic force. Since
the electric potential or voltage of an object
ELECTROSCOPESElectron multipliers are often used
as a detector of ions that have been separated by a
mass analyzer of some sort
MULTIPLIERAFaraday cup is a metal (conductive)
cup designed to catch charged particles in vacuum.
The resulting current can be measured and used to
determine the number of ions or electrons hitting
an electromechanical instrument for detecting and
measuring electric current. The most common use
of galvanometers is as analog measuring
instruments, called ammeters, used to measure
the direct current.
GALVANOMETERAHall effect sensor is a transducer that
varies its output voltage in response to a magnetic
field. Hall effect sensors are used
for proximity switching, positioning, speed
detection, and current sensing applications.
Detector (MAD) is an instrument used to detect
minute variations in the Earth's magnetic field. The
term refers specifically to magnetometers used by
military forces to detect submarines.
FIELDAMagnetometer is an instrument
that measures magnetism either magnetization of
magnetic material like a Ferro magnet, or the
direction, strength, or the relative change of
a magnetic field at a particular location.
MAGNETOMETERMagnetoresistance is the
tendency of a material to change the value of
its electrical resistance in an externally-
applied magnetic field. There are a variety of
effects that can be called Magnetoresistance.
MAGNETORESISTANCEAMEMS-basedMagnetic 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
SENSORAMetal Detector is an electronic
instrument which detects the presence
of metal nearby. These are also used to detect
foreign bodies in food, and in the construction
industry to detect steel reinforcing bars in concrete
DETECTORThePlanar Hall Sensor is based on the
planar Hall effect of ferromagnetic materials. It
measures the change in
anisotropic magnetoresistance caused by an
external magnetic field in the Hall geometry.
SENSORARadio Direction Finder (RDF) is a
device for finding the direction, or bearing, to
a radio source. The act of measuring the direction
is known as radio direction finding. RDF is widely
used as a radio navigation system, especially with
boats and aircraft.
FINDER CIRCUITVoltage detector:
A test light, test lamp, voltage tester, or mains
tester is a simple piece of electronic test
equipment used to determine the presence or
absence of an electric voltage (usually alternating
current (AC) ) in a piece of equipment under test.
