Domestic eddy current proximity switch

JGAPH-FG2X Industrial Eddy Current Proximity SwitchIt has the advantages of good dynamic response, non-contact measurement, and the ability to work in harsh environments, and can detect various metal objects. It uses conductive objects to generate electromagnetic fields when approaching the proximity switch, causing eddy currents inside the object. This eddy current reacts with the proximity switch, causing changes in the internal circuit parameters of the switch, thereby identifying the presence or absence of conductive objects moving closer and controlling the on or off of the switch. The object that this proximity switch can detect must be a conductive material.

Typical Applications
Power plant: Boiler and waste heat boiler combustion monitoring

Steel mills: billet continuous casting, slab continuous casting, billet heating furnace, bar and wire rolling line, slab heating furnace, plate and strip hot rolling line, plate and strip hot rolling coiling, plate and strip hot rolling post-treatment line, cold rolling production line

Cement: Monitoring of working conditions of rotary kiln head/grate cooler
Glass: Monitoring of Glass Melting Furnace Operating Conditions
Metallurgy: Monitoring of blast furnace/heating furnace operating conditions
Petrochemical: Monitoring of various tubular heating furnace operating conditions
Garbage disposal: monitoring of burner and incinerator operating conditions

JGAPH-FG2X Industrial Eddy Current Proximity SwitchIt belongs to a position sensor with switch output, which consists of an LC high-frequency oscillator and an amplification processing circuit. It uses a metal object to generate eddy currents inside the object when it approaches the oscillation induction head that can generate an electromagnetic field. This eddy current reacts on the proximity switch, causing the oscillation ability of the proximity switch to decay, and the parameters of the internal circuit to change, thereby identifying whether a metal object is approaching and controlling the on or off of the switch. The object that this proximity switch can detect must be a metal object.

Precautions for use and installation of proximity switch JGAPH-FG2X

1) When installing proximity switches on metal, a certain amount of space should be reserved to avoid the switch from being disturbed by other metals outside the detected object and causing misoperation. The metal parallel to the sensing surface should be outside the detection distance three times the distance from the sensing surface. The metal around the axis of the proximity switch should be outside the cylinder with the proximity switch axis as the center and three times the diameter of the proximity switch as the diameter.

2) When installing two or more proximity switches simultaneously, in order to prevent mutual interference between any two, when the switches are facing each other, the distance between the two sensing surfaces in the axis direction should be greater than five times the detection distance. When installed in parallel, the distance between the outer cylindrical surfaces should be greater than three times the length of the proximity switch diameter. If the switch diameters are not equal, they should be calculated based on the diameter of the larger proximity switch.

Capacitive proximity switch is also a type of position sensor with switch output. Its measuring head is usually composed of one electrode of the capacitor, while the other electrode is the object itself. When the object moves towards the proximity switch, the dielectric constant of the object and the proximity switch changes, causing the circuit state connected to the measuring head to also change, thereby controlling the on and off of the switch. The detection object of this proximity switch is not limited to metal conductors, but can also be insulating liquids or powder objects. When detecting objects with lower dielectric constant ε, the multi turn potentiometer (located at the back of the switch) can be adjusted clockwise to increase the sensing sensitivity. Generally, the potentiometer is adjusted to make the capacitive proximity switch operate at the position of 0.7-0.8Sn.
