Isolator Bases Protect 1,500 V
Targeting accelerometers, Wilcoxon Research's SF21, SF22, SF23 and SF24 isolater bases protect a vibration sensor from up to 1,500 V for as long as one minute and withstand temperatures up to 120ºC. The SF21 and SF22 are both 1" (25 mm) across the flats with a 0.820" (20-mm) mounting pad that can accommodate up to medium diameter Wilcoxon accelerometers that range in size from 780 to 786 A and small diameter side-exit accelerometers, such as the 775 A. The SF23 and SF24 isolator bases are both 1.125" (29 mm) across the flats with a 0.940" (24-mm) mounting pad that can accommodate large diameter Wilcoxon top-exit sensors that range in size from the 793 to the PC420 4-20 mA vibration sensor series. The isolator bases have a 1/4-28 integral stud on the accelerometer side and the stud on the side that mates with the machine, the bottom, can be ordered in two common sizes, either 1/4-28 or M8.
