Warner Instruments' LPF-8 signal conditioner combines an eight-pole, low-pass Bessel filter with a DC amplifier.
Warner Instruments' LPF-8 signal conditioner combines an eight-pole, low-pass Bessel filter with a DC amplifier.
Special features of the LPF-8 include digital frequency readout, visual input offset, clipping indicator and gain telegraph outputs.
The circuit design uses no mechanical switching to ensure long-term reliability.
The cutoff frequency is dialed up using a single rotary control in two ranges.
The full frequency range spans 0.1Hz to 20kHz in a resolution of 0.1Hz or 10Hz, depending on the range selected.
The bypass switch selects full amplifier bandwidth for comparison of filtered and unfiltered signal.
Applications for the device include signal conditioning for the biomedical, medical, electrical engineering, physics, seismic analysis, vibration analysis, industrial process control and general laboratory environments.
