Description

This low flow transducer is for animals such as mice or rats and includes a detachable flow head (RX237 series) and a differential pressure transducer (TSD160A).

One of the problems that has been encountered with pneumotachographs is condensation from expired air. This can be prevented by fitting a non-return valve and measuring only inspiration or alternatively by heating the flowhead, but viscosity errors may arise which, in the first few breaths especially, preheat the inspired air most uncomfortably. In this range of flow heads, the problem is approached from a fresh angle. By mounting a fine stainless steel gauze in plastic rings, the thermal inertia is greatly reduced. The gauze therefore rapidly equilibrates in temperature with passing air and condensation is minimal.
