Current Sensor
The document introduces different types of current sensors produced by Honeywell, including digital/inductive, closed loop, and open loop current sensors. Digital/inductive current sensors use feedback control and provide accurate outputs proportional to measured current. Closed loop sensors provide a digital output indicating when sensed current exceeds a threshold, while open loop sensors output a value proportional to current without feedback. The document provides details on specific sensor models and their applications.

Editor's Notes
- #2 This is a training module on the Honeywell Current sensor
- #3 Welcome to the training module on the Honeywell Current sensor. This training module introduces different types and features of a current sensor and its application.
- #4 Honeywell offers a wide variety of current sensors to monitor alternating (ac) or direct (dc) current. From digital output detectors sensing a few hundred milliamps to linear sensors monitoring over one thousand amps, Honeywell line provides superior performance at a reduced cost. It has been categorised in three types of current sensors: Digital/Inductive Current Sensors, Closed Loop Current Sensors, Open Loop Current Sensors. When any of these sensors detect predetermined signals, the system then performs the designated task. For instance, the digital signal’s logic level output may sound an alarm, start a motor, or open a valve.
- #5 This Page gives you information about a Digital / inductive current sensor. It Uses feedback control and Provides output proportional to measured current and it also has High accuracy and linearity, Fast response, Low temperature drift and its Output is relatively immune to electrical noise.
- #6 This page explains about the CSDA Series Digital / Inductive current sensors, these current sensors produce a digital logic level output. When the current being sensed reaches a predetermined level, the output changes state. Its Output voltage is isolated from the input, it has a 40mA current sinking output. Its major application areas includes motor overload protection, monitoring system, power loss detection. CSDA Series digital current sensor specifies a 0.25 A to 1.0 A operating current, through-hole design, logic level sinking output, operates on AC or DC current, pin-out style 1 PCB pins.
- #7 This Page gives you information about a Closed Loop current sensor. It has around fifteen series of sub-category products which is presented in further slides. It can sense current up to 1275A, it is available in in-line or thru-hole design, it has reduced overshoot and has high overload capability. This closed loop current is the output from the device and presents an image of the primary current reduced by the number of secondary turns.
- #8 Closed loop current sensors measure AC, DC and impulse currents over 0-25, 0-50, 0-100, 0-600 and 0-1200 Amp ranges. The CSN Series is based on the principles of the Hall effect and the null balance or zero magnetic flux method (feedback system).

The features includes Sensed current range, supported current type (AC/DC) output form, No of coil turns, the response time, its accuracy, mounting type and supply voltage. This current sensor utilizes an ASIC and a magnetic sensor to provide extremely low offset drift with temperature resulting in stable, repeatable and accurate measurement.

They offer increased current measuring capability up to 1000A over an extended temperature range of -40°C to +85°C and are available with different terminal options. The sensors are closed loop devices based on the principle of the hall effect and null balance method. The output from the current sensor is the balancing current which is a perfect image of the primary current reduced by the number of secondary turns at any time. This current can be expressed as a voltage by passing it through a resistor.
