PCB Piezotronics, Depew, NY, offers the Model 482C24 4-channel signal conditioner that includes DC coupling selectable on a per-channel basis. It is suited for use with ICP® force and pressure sensors that have long discharge time constants, allowing temporary measurements down to 0 Hz. An autozero function automatically negates DC bias. A clamped output feature (when AC coupled) provides a positive-only signal that electronically re-zeros each pulse before the next cycle. Features include a front panel keypad and display, and an RS-232 port for computer control.
