Overview
The EMC Shop is an ISO 17025 accredited calibration company with the ETS-Lindgren HI-4433-STE Isotropic Electric Field Probe in stock available for sale or rental. Repair and refurbishment services available as well. Contact us now for application support.
The HI-4433 series comprises a family of battery-operated broadband radio frequency (RF) isotropic field probes designed for use in making RF exposure measurements in the vicinity of broadcast facilities and industrial RF sources. These probes use optical isolation to minimize field perturbation during measurements. Each probe in this series has characteristics that optimize its performance for a particular application. Model number differentiates individual probes for example HI-4433-XXX, where XXX defines the specific probe.
Each HI-4433 series probe assembly consists of a spherical casing containing the sensor mounted on one end of a shaft. The other end of the shaft is attached to an extrusion that houses the electronics. The sensor and electronics housing
operate, and are calibrated, as a unit. Since the appearance and layout of the electronics housing are the same for all probes in this series, both the probe assembly and the housing are coded with identical serial numbers to prevent
mismatch.
HI-4433 series probes measure the field strength in each of three axes. They perform a vector addition calculation on the readings and send the result to the readout via a fiber optic cable. Data from each axis can be viewed individually, or
can be combined. The measurement capability and frequency response of HI-4433 series probes depend upon which model is selected.
