Abstract
A transducer protector having at least two filter membranes. In one embodiment, the transducer protector includes a body between two tubular connectors, each of which has a lumen that may be axially aligned. The body lumen is separated from the lumen of each of the tubular connectors by a filter membrane. In one embodiment, the body is transparent and the body lumen has an indicator to alert a user that the filter membrane has been breached by a contaminant so that the user can take immediate steps to prevent further contamination of the system. The configuration of the transducer protector also facilitates the use of separate indicator devices, such as sensor clips.
