The AST5400 differential pressure (DP) transducer can measure line pressures up
to 5,000 PSI with a turndown ratio of 15 to 1. Using Krystal Bond™ Technology, the
AST5400 contains no silicone oil, O-rings, or welds. This MEMS pressure sensor
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. The AST5400 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.
With its digital compensation, this series offers excellent linearity and performance
over temperature. The electronics now offer a fail safe condition on the output
signal. If the transducer were to experience a fault condition, the transducer can
be programmed to rail 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. The AST5400 also offers excellent flexibility in its
configuration, allowing for a variety of wetted materials and pressure ports.
