MEMS differential pressure sensor for liquids and gases

New sensor family from AST handles high pressure limits and wide turndown range.

American Sensor Technologies, Inc. offers the AST5400 wet / wet differential pressure sensor to measure line pressures up to 2,000 PSI with a turndown ratio of 15:1. American Sensor Technologies, Inc. offers the AST5400 wet / wet differential pressure sensor to measure line pressures up to 2,000 PSI with a turndown ratio of 15:1. This cost-effective unit offers many features needed by process industries combined with an economical price. The AST5400 differential pressure sensor can be used to measure differential pressure across a filter, monitor level in a sealed or vented tank, or calculate flow across an orifice plate. 

AST says that using its Krystal Bond technology, these sensors contains no silicone oil, O-rings, or welds, and with its high line pressure capability, this design can be installed into systems without five-way equalization valves, thus saving users hundreds of dollars per installation. This MEMS technology completely isolates the media to the pressure ports, thus eliminating contamination risk. The low strain level on the diaphragm results in accurate, repeatable measurements over a long service life.

The AST5400 replaces systems that use two gauge pressure sensors to calculate differential pressure, saving on installation time and cost. Because the error of two sensor systems is additive, this approach can easily increase performance over temperature.

With advancements in electronics, users of differential pressure switches can now make use of a sensor to monitor system performance and trends in applications requiring a high turn-down and high cycle performance. Alarm functions can be added through most controllers, thus making the need for a separate pressure switch obsolete.

With digital compensation, the AST5400 series provides excellent linearity and performance over a wide temperature range. The electronics offer a failsafe condition on the output signal: if the transducer experiences a fault condition, it can be programmed to move the output signal to 10% below the minimum, or 10% above maximum output signal to notify the user of an issue and protect the system from undesirable conditions.
