YAS538 Series - Current Sensor
(Part CS-60v)
 YAS538 CS-70v Overview |
Automotive GMR Current Sensor - CS-70v
The new Yamaha CS-70v Coreless Magnetic Balanced Sensor device gives high accuracy electric current measurement by using high sensitivity GMR elements. Packaged complete with Integral Busbar, the CS-70 can be used with AC or DC and provides a ratio-metric or non-ratio-metric analogue voltage output.
With no ferrite core required, the design provides for a light weight (1.82g) and compact package (23 x 12mm approx.) which is driven by a 5VDC power supply. The standard unit is capable of measuring up to 50Amps with a sensitivity of 28.3mV/A typical. Custom designs can be considered which would increase the measuring range dramatically and Willow welcomes any enquires of this nature.
Present demand for these highly innovative current sensing assemblies stems from the automotive, industrial, electric utility and home electronics (electric tools) markets, with applications ranging from monitoring of auxiliary and electric vehicle batteries, inverters for motor driving, power conditioners, smart meters and energy management systems.
CS-70v exhibits excellent performance over a wide temperature range with offset temperature drift less than +/-6mV and sensitivity temperature drift of less than +/-1%. Linearity is 0.05%FS (max.) with response time at just 1.0µs and frequency response of 400kHz. Current consumption is very low at 6mA for 0A and 16mA for 50A on the busbar. Dielectric voltage to 2.5kV, the device has creepage & Clearance of 7.53mm and 6.75mm.

GMR Current Sensor - CSC-1U for Smart Metering
The new Yamaha CSC-1U Current Sensor IC device gives high accuracy electric current measurement by using high sensitivity GMR elements. Available in a SIP4 package, the CSC-1U can be used with AC or DC and provides a ratio-metric or non-ratio-metric analogue voltage output.
With no ferrite core required, any design using this IC will provide a compact package (IC size 5 x 4mm approx.) which is driven by a 5VDC power supply. Partnering the IC is a packaged version complete with bus bar, which is capable of measuring up to 50Amps with a sensitivity of 28.3mV/A typical. Custom bus bar package designs can be considered which would increase the measuring range dramatically and Willow welcomes any enquires of this nature.
