<p>A condensate trap comprises a trap element 12 disposed in a trap chamber 6, and a sensor chamber 16 containing a sensor element 24 for monitoring the performance of the trap element 12. The sensor chamber 16 communicates with the trap chamber 6 through a first passageway 26 and one or more second passageways 28. The first passageway 26 opens into the sensor chamber 16 at an upper region of the sensor chamber, while the second passageway 28 opens at a lower region, so that the sensor element 24 is situated at a level above the lowermost part of the port at which the second passageway 28 opens into the sensor chamber 16. If the trap element 12 does not close the outlet 10 properly, condensate accumulating in the sensor chamber 16 will be forced into the trap chamber 6 through the second passageway 28, and the level will fall to expose the sensor element 24 which will react to provide an alarm signal. <IMAGE></p> |
