Current Sensors
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, our comprehensive line provides superior performance at a reduced cost as well as the thru-hole design, output voltage isolation from input, minimum energy dissipation, enhanced reliability with adjustable performance and built-in temperature compensation
Closed Loop Current Sensors
Closed loop current sensors use feedback control to provide output proportional to measured current.
Engineered with enhanced accuracy and linearity to deliver fast response. Output relatively immune to electrical noise. Potential applications include variable speed drives, Servo, overcurrent protection, ground fault detectors, robotics, power supplies, and wattmeters.
Open Loop Current Sensor
Open loop current sensors provide output voltage proportional to measured current without using feedback control. They are often preferred in battery powered circuits due to their compact size and lower power consumption. Potential applications include welding machines, variable speed drives, UPS and overcurrent protection.
Digital/Inductive Current Sensor
Each Honeywell CS series digital current sensor provides a logic level output that changes from approximately Vcc to 0.4 volts when the sensed current exceeds the operate point.
Each digital sensor will operate on ac or dc current, but the output will turn off at every zero crossing when sensing AC current.
