Overview
The ETS-Lindgren EMSense 40 is a precision electric field probe designed for accurate, real-time field strength measurements in EMC and RF test environments. Featuring isotropic sensors, it enables reliable detection of electric fields in all directions, ensuring consistent and repeatable measurement results across a wide range of applications.
The EMC Shop customers use the EMSense 40 to monitor electric field levels during radiated immunity and EMC compliance testing. In test setups, engineers connect the probe via USB or fiber optic interface to EMCenter platforms, allowing fast data acquisition and continuous measurement of field strength within anechoic chambers or test sites.
For system validation and troubleshooting, the EMSense 40 is used to verify field uniformity, optimize test configurations, and ensure that required field levels are achieved across the test area. Its stable performance and real-time monitoring capabilities make it a reliable tool for engineers working in R&D, compliance testing, and RF system evaluation.
