The SS40L-SS42L series differential pressure transducers are designed for low range pressure monitoring. These transducers plug directly into the CH input on MP36, MP45, or MP36R  data acquisition units. The differential pressure ports are located on the front of the transducers and are easily connected to breathing circuits, pneumotachs or plethysmograph boxes. These transducers are very useful for interfacing a variety of small animal pneumotachs or plethysmographs to the BIOPAC System.
