A self-contained system to continuously monitor a mechanism used to process, control or regulate fluid flow or pressure and provide a continuing indication of the status or condition of the monitored mechanism. A specific form of the invention employs a low frequency sonic-to-electrical transducer that monitors opening and closing of a disk-type steam trap. The detected sonic signal is processed and sent to a microprocessor that is programmed to develop a time-based, baseline data set representative of normal operation of the steam trap in the environment in which it operates. The baseline data set is compared with the data from on-line operations of the steam trap. As the environment and the steam trap operation change during normal on-line operations, the baseline data set is updated to change with the changing environment and the changing steam trap operation.

The present invention relates to a system and method for sampling a gas flow to measure one or more contaminants within a semiconductor processing tool. The system includes a portable unit containing one or more dry traps, Tenax traps and, if desired, wet impingers. The unit is coupled to a gas flow in a clean room and the dry traps. Tenax traps and wet impingers measure contaminants contained in the gas supply for a determined sampling interval. When the sampling interval is done, the unit is sent to an analysis facility for processing.

Electronic steam trap monitoring is disclosed. An electronic steam trap monitor is operably coupled to an outlet of a steam trap and is configured to measure at least one process variable of fluid (liquid or gas) flowing through the trap, when the trap is known to be working normally. The steam trap monitor stores the process variable information obtained during the known operating condition for later comparison. The steam trap monitor obtains a later process variable measurement and compares it to the stored measurement to selectively generate a leakage indication. The steam trap monitor preferably uses a local power source and communicates wirelessly.

Disclosed is a system for supporting sales and maintenance activities of steam traps by a seller of the traps to a customer. The system utilizes an aggregating system which effects a step of inputting stored diagnostic result data and model confirmation result data from a diagnostic device which has diagnosed a working condition of each of a plurality of existing steam traps installed in a customer's plant. Based on the diagnostic result data, a first total steam loss amount due to malfunction of steam traps is calculated, the first total steam loss amount comprising aggregation of steam leak amounts of all the existing steam traps. Based on the model confirmation result data, a second total steam loss amount is calculated, which comprises aggregation of differences between inherent steam leak amounts of the existing steam traps under their normal working conditions and inherent steam leak amounts of recommended steam traps under their normal working conditions. A monetary conversion value of an integrated value of a sum of the first total steam loss amount and the second total steam loss amount integrated for a predetermined period is calculated. Comparison data is generated allowing comparison between the monetary converted value and a replacement cost required for lump-sum replacement of all the existing steam traps by the recommended steam traps. The comparison data is outputted for presentation to the customer in sales and/or maintenance activities of the recommended steam traps.

The present invention provides a conduit trap, which can also operate as condensation recovery device when installed in a refrigeration system drainage line. The conduit trap is generally a hollow body defining a fluid path that includes an upper conduit 20, having a waste outlet 30 and optionally a condensation collection outlet 32. A lower conduit 22 extends downwardly from the upper conduit and has a narrowing that creates an inner sealing region for receiving a sealing means, such as float 50. Condensation can be directed from the refrigeration system through the conduit trap for recovery or for disposal without exposing the refrigeration drainage line and occupied space in which the refrigeration unit is located to sewer gasses even in dry weather when a gravity based, fluid-filled trap would fail.
