1.Open Loop Hall Effect Current SensorPrincipleHall Effect Open Loop Current Sensor is a current measurement device which develops on base of the hall effectprinciple, wherein a Hall-effect device(HED) produces an output voltage linearlyrelated to the amplitude and phase of amagnetic field applied to it.

AdvantagesEasy installation

Can be customized

No insertion losses

Low power consumption

Wide current measuring range

High immunity to external interference

2.Closed Loop Hall Effect Current SensorPrincipleHall Effect Close Loop Current Sensor develops on the principles of the Magnetoresistive or Hall effects, and thenull balance or zero magnetic flux method.Primary current Ip provides the magnetic flux which will be balanced by a complementary flux produced by drivinga current through the secondary winding, so the positive and negative magnetic field reaches balance to detect thecurrent.In other words, the secondary current, IS,creates a flux equal in amplitude, but oppositein direction, to the flux created by the primarycurrent.This current can be expressed as avoltage by passing it through a resistor.

AdvantagesHigh accuracy

Very good linearity

Easy installation

Can be customized

Low temperature drift Optimized response time, no insertion losses

Low power consumption High immunity to external interference



3.Hall Effect Voltage SensorPrincipleThe principles of Hall Voltage Sensor is the same as the closed loop hall current sensor, but need to convert thevoltage of the primary terminal to current through the resistor R1.So the hall voltage sensor is also used to testcurrent signal, and the output compensation current/offset current can accurately reflect the changes of primaryvoltage signal. To select the right R1 value, please choose different sensors based on the test voltage and power.

AdvantagesHigh accuracyVery good linearityEasy installationCan be customizedLow temperature driftHigh immunity to external

interference

4.Current Transmitter/TransducerPrincipleCurrent transmitter is a current measurement device which develops on base of the hall effect principle. It canaccurately measure various types of DC, AC voltage, which is widely used in the electrical power supply,communication power and other fields.

AdvantagesEasy installationCan be customizedNo insertion lossesLow power consumptionWide current measuring rangeHigh immunity to external interference

5.DC Leakage Current TransducerPrincipleDC Leakage Current Sensor develops based on magnetic modulation closed loop principle, to measure tinycurrent (mA level). DC leakage current measuring range can reach 0～±200mA.



AdvantagesHigh accuracyVery good linearityWide current measuring rangeCan be customizedOptimized response timeLow power

consumptionHigh immunity to external interference

Inductive Proximity Sensor: LJK/LJB Series DC Cylinder-shaped Sensor

Introduction Principle: Inductive Proximity Switches are developed based

on a coil and high frequency oscillator that creates a field inthe close surroundings of the sensing surface. The presence ofmetal in the operating area causes a change in the oscillationamplitude. This change is identified by a threshold circuit,which changes the output of the sensor.

Standard Detected Object: Inductive proximity sensors detectthe presence, movement and position of metallic objects.

The operating distance of the sensor depends on the coil’s sizeas well as the target’s shape, size and material.

It is divided into two categories according to the workingstate :JK - normal open type,JB - normal closed type

Features: Contactless detection of metal objects, to avoid

damage to the sensor itself and the target. No contact output, high reliability, stable operation

and long service life High repeatability positioning accuracy and excellent

measurement accuracy Small sensor, flexible installation.
