Transducers - Application
The main purpose of using electric transducers is to obtain an isolated low-voltage analog or digital signal reflecting the instantaneous value or effective electrical value measured with sufficient accuracy in a given frequency band. This signal can be read or recorded on a meter or monitor, as well as processed to control electrical systems in any processes and devices, ie: converters and inverters, speed controllers for DC and AC motors, robots and automata, buffer and uninterruptible power supplies, electric welders, traction drives, electrical and traction substations
LEM electrical transducers
Electric transducers transform the primary current into a galvanically isolated signal proportional to the instantaneous or effective value of this current in a wide frequency band from 0 to 800 kHz.
They are used to measure constant and variable currents up to 20 kA (for industrial applications and electric traction) and very high currents in galvanic processes up to 500 kA and voltages up to 6400V of effective value.
The basic parameters needed to select the transducer:
- Measured quantities and their values.
- Supply voltage Vc: e.g. 0±12V, 0±15V, 0±24V, +5V, +12V, +24V.
- Frequency band: e.g. 0-50kHz, 0-200kHz, 0-5kHz, 10Hz-6kHz.
- Operating temperature range: e.g. -10...+70°C, -40...+85°C.
- Operating voltage, test voltage isolation upto 18.5kV 50 Hz 1 min.
- Mounting method: for printing, self-contained modules, window dimensions.
- Connection type: e.g. metric (M4, M5), Fast-on, Molex, cable.
- Output signal: e.g. voltage 0-4V, 0-10V, analog current 25-1000mA, compatible with 4-20mA, 0-10V PLC.
- Measurement accuracy: own, total system.
- Standards e.g. EN50178, EMC (89/336/EEC), traction EN50155.
- Electromagnetic compatibility CE.
- Warranty 5 years.
