Features: • Excellent linearity, linear error εL ≤ 3ppm · low temperature drift, offset current temperature coefficient TCIOE <0.3ppm / □ K · 200kHz wideband ultra-low output noise, Beijing, China, February 4, 2010 - Recently, the world's leading current and voltage measurement components manufacturer Lime (LEM), announced the launch of its new high-precision ITL 900-type current sensor, it is the most accurate current sensor on the market, can accurately measure and control the DC , AC and pulse currents, range up to ± 900A, can be widely used in industrial, medical and instrumentation fields. ITL 900 in the normal operating temperature range (10 □ C to 50 □ C) the linearity error (εL) less than or equal to 3ppm, 4 hours, the stability of the offset is less than 0.5ppm, offset current temperature coefficient (TCIOE) small At 0.3ppm / □ K. ITL 900 with a new current sensor is greater than 200kHz (-3dB) of the large measurement bandwidth, fast transient current can be accurately measured. In addition, it has the following advantages: Since the magnetization is negligible, the current overload capacity, high-power between the primary circuit and secondary circuit configuration of the current isolation. ITL 900 of the output noise is also very low, at 50 or 60Hz, its random noise is less than 15 □ Atrms, coherent noise is less than 50 □ Atrms. ITL 900 and an external clock signal used to synchronize the internal clock, which helps to improve the periodic noise immunity. ITL 900 through the LEM is based on adjusted and improved closed-loop axis fluxgate technology. In general, based on open loop (without compensation) of conventional Hall effect sensor technology can not provide many applications need ultra-low nonlinearity error, background noise or offset thermal drift, such as magnetic resonance imaging (MRI) on High-performance gradient amplifiers or accurate current regulation device, which is widely used in high-precision power supply, power supply test bench equipment and laboratory analysis calibration and measurement instruments. ITL 900 attached CE mark, and, like all other LEM industrial products 5-year warranty.
