A REVIEW OF FILTER PRESS BASICS AND ISSUES VERSUS ALTERNATIVE BATCH OR CONTINUOUS REPLACEMENT TECHNOLOGIES

INTRODUCTION

Filtration experts, over the years, have discussed and debated filter presses and have indicated that soon they would be a thing of the past; the last filter press would be replaced by more modern equipment. Given that filter presses were amongst the ... (read more)

Conec filter plates provide EMI/RFI filtered signal lines between electronic modules and systems.

The KH Model 3955 programmable, dual channel, low-pass filter is the first dual low-pass programmable filter of its kind, covering the wide cutoff frequency range from 170Hz to 25.6MHz with 2 digits of resolution. The 3955 is a 4-pole, maximally flat (Butterworth) filter, with an attenuation slope of 24dB/octave and a stopband attenuation of >100dB referred to 1Vrms input. (read more)

The KH Model 3380 Filter Series are one, two or four channel filters providing ease of operation and the reliability Krohn-Hite has been known for since 1949; along with a price that will fit any budget. (read more)

The KH Model 3940 programmable, dual channel, Butterworth/Bessel filter is a GPIB/benchtop filter covering a cutoff frequency range from 3Hz to 2MHz. Attenuation slope is 24dB/octave per channel. The 3940 will accept input levels of ±4.5V peak. Pre and post-filter gains of 0dB or 20dB is also provided. All functions are front panel or GPIB bus controlled. (read more)
