ETS-Lindgren's laser-powered EMSenseTM 40 Electric Field Probe embodies the latest innovations in isotropic sensor design, low noise and miniaturized electronics. Designed to be single range reading, the EMSense 40 can read data continuously over the entire dynamic range. Data values for each axis (X, Y, and Z) can be read individually or summed. Fiber optic signal and power lines link the RF field probe to either the EMCenter 2/7 Slot, or as a direct connect to a PC USB port with the EMCenter 1-Slot.

The EMCenter 2 and 7 Slot Modular RF Platform along with the EMSense 40 interface card can be used as a Field Monitor in addition to its capability as a system level platform.

The EMCenter 1-Slot with the EMSense 40 interface card provide laser power and communications for the EMSense 40 Field Probe. A USB connection to the PC allows for quick and easy data collection, using ProbeView V software.

Product Features

The EMSense 40 probe utilizes an updated CPU in the EMCenter to support its improved communication speed. Some EMCenter units carry an older CPU that must be upgraded to support the EMSense 40 probe and plug-in card. To check compatibility, access the " Info" menu on the EMCenter main screen and check slot 8. The compatible processor is 7000-008. If the EMCenter shows processor 7000-007, a processor upgrade is available through the ETS-Lindgren service center.

Alternatively, a stand-alone EMCenter is available for EMSense 40 that appears as an additional EMCenter slot to EMC control software.
