CANWAY Current Clamp Meters


CANWAY Current Clamp Meter with CAN-Interface

ATI is pleased to offer CANWAY Current Clamp Meter with Can-Interface for Test Cell measurement. CANWAY’s CW-401 MKII is a precision clamp meter that can communicate with ATI’s CAN interfaces and ATI branded Kvaser interfaces. The CW-401 MKII provides a quick and effortless setup and tear down through the ability to easily attach and remove the clamp from any system being monitored. The small stature of the clamp makes it the ideal choice for small spaces such as on vehicle testing. Additionally, the CW-401 accommodates a wide measuring range with clamps rated for ±10 A, ±30 A, ±50 A and ±150 A.
CANWAY Current Clamp

User-friendly read out of measured current values via CAN bus. That allows the measured values to be transmitted interference-free to any desired evaluation unit including over large distances. In conjunction with the CW-101 CAN USB interface it is possible to configure a clamp meter via CAN bus. That means with the aid of the intuitive configuration software it is very easy to define the output transmission rate, CAN ID, bit rate, mean value generation and more. Moreover, it is possible to configure several clamp meters at the same time and export a DBC file, for example for use in a measuring chain.

Product Features:
  • Versions for the measurement ranges: ±10 A, ±30 A, ±50 A and ±150 A
  • 1 % additionally ± 50 mA (relative to measuring range)
  • Temperature range: -40 °C to +120 °C
  • Temperature compensation, sensor position- and magnetic remanence correction 
  • Measured value output via CAN bus 2.0 A/B (ISO 11898-2)
  • Robust aluminium housing
  • Small form factor makes it possible to reach even difficult-to-access measuring points
  • Calibrated inhouse  (DAkkS – German accreditation body – on request) 
  • Intuitive configuration software
