January 16, 2011
The AST5400 from American Sensor Technologies Inc., Mt. Olive, NJ, is a wet/wet differential pressure sensor to measure line pressures to 2000 psi with a turndown ratio of 15:1. The device can be used to measure differential pressure across a filter, monitor level in a tank, or calculate flow across an orifice plate. Features include no silicone oil, O-rings, or welds; complete isolation of media from pressure ports; digital compensation; ability to be installed into systems without five-way equalization valves; and a fail-safe condition on the output signal to notify the user of an issue and protect the system should the transducer experience a fault condition.
