Consult F.W. Bell if the product of the aperture current and frequency exceeds 1000 ampere-kilohertz for the BBP-150H and 400 ampere-kilohertz for the BBP-300H and the BBP-600H. 2. Response time is affected by the positioning of the conductor in the aperture, the proximity of the return conductor and ferrous metals. It is best to test the sensor in the actual environment to obtain representative performance. 3. The sensors are calibrated at 80% of Full Scale. 4. Hysteresis specifications given for Full Scale aperture current remnant. 5. The dielectric text consists of 4.0 kVac at 60 Hz for one minute between a bare 0.775 inch diameter conductor (located concentrically through the aperture) and the output of the sensor. 6. Due to continuous process improvement, all specifications are subject to change without notice. 6120 Hanging Moss Road • Orlando, Florida 32807 Phone (407) 678-9748 • Fax (407) 677-5765 • www.fwbell.com Rev. date 04/2003
