A transducer protector (10) having at least two filter membranes (50, 60). In one embodiment, the transducer protector includes a body (40) between two tubular connectors (20, 30), each of which has a lumen (22, 32, 42) that may be axially aligned. The body lumen (42) is separated from the lumen (22, 32) of each of the tubular connectors by a filter membrane (50, 60). In one embodiment, the body is transparent at least in part and the body lumen has an indicator (70) 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. <IMAGE>
