Description
These Solid-State Current Transducers convert a primary AC circuit current to a proportional Analog signal (4-20mA), which allows the Current Usage to be monitored by a wide range of Data Loggers plus Data Acquisition, SCADA and BMS Systems. They are used to monitor the current for Electrical loads such as pumps, conveyors, machines or fans.
The CSG-675 series of current sensors are loop powered to allow longer cable lengths to be used. The sensors are typically used to monitor motor operation and can be used to determine motor failure, belt loss, machine feed rates or tool wear. A plug-top power supply is available from under the Recommendations Tab.
The CSG-675 series feature true RMS current measurement and are suitable for measuring complex waveforms such as those found in Variable Frequency Drive (VFD) controlled loads. They are also suitable for accurate measurement of phase-angle controlled or time-proportional Silicone Controlled Rectifier (SCR) controlled load current. The CSG-675 Series contain a precision RMS-to-DC converter circuit which will measure load current accurately for complex, distorted or noisy waveforms as opposed to “average reading” devices that will only measure pure sine waveforms accurately.
The CSG-675 series are Split-core to allow for easy retro-fitting and are now available in five versions: (0-2A, 0-5A, R1 = switch selectable 0-10A, 0-20A or 0-50A, R2 = Switch selectable 0-50A, 0-100A or 0-150A plus a 0-200A version).
IMPORTANT: Please specify the range required in the comments section of your order.
