Current and Voltage Sensors

GLOBETEK is the Exclusive Representative in India for Products manufactured by LEM SA, Switzerland.

LEM SA is highly specialised Swiss engineering company founded in 1972 leverages more than 4 decades of its experience and is focused on the design, development and production of Current and Voltage transducers. LEM SA, Switzerland manufactures high-quality electrical parameter measuring instruments. They produce devices that can measure all critical factors like current, voltage, and resistance with extremely high accuracy. The most popular products by LEM include current and voltage transducers.

These transducers are used in a wide range of applications like drives, welding, traction, high precision conventional and green car businesses, as well as renewable energies and power supplies. Working with the LEM voltage sensors will give you consistently reliable readings for decades to come. LEM only uses the best materials for its wide range of current and voltage sensors that can resist wear and tear for a long period easily.

The LEM transducers are known for their exceptional speed and accuracy. Most transducers experience a lag or a hysteresis loss when it comes to prolonged exposure to the current. However, LEM transducers work smoothly under such conditions. Also, these transducers are known to control the energy consumption smoothly for all types of electric signals. LEM has mastered the use of its core business techniques and used the innate strength in order to generate new opportunities in various electrical sectors. The sales of world-renowned current and voltage sensors have added to the growth of the business in an unprecedented way.

Their core products i.e., current transducers and voltage transducers are used in a broad range of applications.

  • Industrial Transducers
  • High Precision Transducers
  • Traction Transducers
  • Automotive Transducers
  • Energy and Automation Transducers

The LEM current and voltage transducers find applications in various industries. Some of the popular large-scale industries where we supply the LEM products include general, automotive, railway and as well as energy measurement sectors. The transducers are also used in high-level applications with relation to the railway on-board, energy and automation purposes. They are also used in Wi-LEM – wireless sub-metering networks to measure the energy consumption effectively. LEM also manufactures high-quality voltage sensors that are used in heavy industrial applications. These voltage sensors have both a high precision as well as accuracy that can sustain a heavy usage for a long period easily.

The LEM range of products contains over 2500 different products serving the needs of multiple industries. LEM is known to manufacture transducers that are reliable, galvanically isolated and highly accurate. These devices can measure current as well as voltages with high precision. The current measurement range goes from 0.25A to 24000A whereas the voltage measurement range goes from 10V to 6400V. The transducers use the following technologies:

Hall Effect

  • Open Loop Current Transducer
  • Closed Loop Current Transducer
  • Closed Loop Voltage Transducer


  • Closed Loop Fluxgate C Type
  • Closed Loop Fluxgate CAS-CASR- CKSR Type
  • Closed Loop Fluxgate CTSR Type
  • Closed Loop Fluxgate ITC Type
  • Closed Loop Fluxgate IT Type

DV & DVL Type Voltage transducers

DI Type Current transducers


  • RT Type Current Transducers

Prime Current Transducers

Split Core Current transformers

AT & TT type

The best part about LEM transducers is they follow the strictest international standards for manufacturing transducers. Some of the most demanding international standards that these transducers follow include:

• EN50178
• EN50124-1
• NFF16101
• NFF16102
• EN50155
• And many more

The transducers also carry the CE marking to denote the high levels of precision and accuracy while manufacturing the product. LEM transducers also bag the UL Recognition (UR) for most of its products. For use across international waters, the transducers rely on the following norms:

• ISO 9001
• IRIS (Geneva and Beijing)
• ISO TS 16949

LEM voltage sensors are made of high-quality heat-resistant materials that have a low hysteresis loss and perform outstandingly over a wide range of temperatures.

Globetek extends the warranty supplied by LEM to all its customers. With the LEM products, you can get a worldwide ISO 9000 and ISO TS16494:2000 qualification along with a long 5-year period of warranty.
