LEM current transducer suits medical applications
LEM
ITL 900 current transducer
LEM's high-accuracy ITL 900 current transducer is designed for the precise measurement of DC, AC and pulsed currents up to +/-900A in a range of industrial, medical and instrumentation applications.
The ITL 900 provides linearity error of less than or equal to 3ppm over an operating temperature range of 10 to 50C, offset stability over four hours of less than 0.5ppm and offset current temperature coefficient (TCIOE) of less than 0.3ppm/K.
The transducer offers a measurement bandwidth of more than 200kHz (-3dB), allowing fast current transients to be accurately measured.
Other advantages include negligible self-magnetisation, a current-overload capability and galvanic isolation between the high-power primary circuit and the electronic secondary circuit.
The ITL 900 also has very low output noise, with random noise less than 15uAtrms and coherent noise of less than 50uAtrms at 50 or 60Hz.
It works on an internal clock that can also be synchronised to an external clock signal, increasing immunity to periodic noise.
The transducer is based on a double fluxgate closed-loop technology that has been adapted and improved by LEM.
The ITL 900 is CE marked and is supplied with a five-year warranty.
