Easy installation for current transducers
LEM has new families of current transducers with an innovative design that dramatically reduces installation time.
Current transducers for milliamp accuracy
The DF series of current transducers provides accurate measurement of low DC currents from 10 to 500mA without breaking the primary cable.
Based on LEM-Flex, LEM's original flexible current probe which is four times lighter than standard clamp-on probes, this probe offers an extended battery life up to 400h and an AC-coupled output.
A number of versions are available: the RR3020 type with 4mm safety plugs for direct connection to multimeters, recorders and data loggers, without additional leads.
The RR3030 type has a BNC connector for connection to oscilloscopes, recorders and data loggers.
The third version, the RR3120 has the same specifications as the RR3020, with a 1V output.
These probes provide an isolated linear output voltage which is a proportional replica of the input waveform with three user selectable input current ranges of 30, 300 or 3000A.
The flexible measuring head offers a 175mm-diameter window and 2m connecting cable.
The operating temperature range is from -20 to +90C.
The measurement accuracy is +/-1% of range and the bandwidth is 10Hz to 50kHz for the RR 3030 type and 10Hz to 20kHz for the RR 3020 type.
The range complies with EN61010-1 600V CAT III pollution degree 2 for input and output circuits and EMC standard EN61326.
