AST5400

Differential Pressure Transducer for Liquids and Gases

The AST5400 differential pressure (DP) transducer can measure line pressures up to 2,000 PSI with a turn-down ratio of 15 to 1. Using Krystal Bond Technology, the AST5400 contains no silicone oil, O-rings, or welds. This MEMSMicro Electro-Mechanical System 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 differential pressure transducer 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, the AST5400 series offers excellent linearity and performance over temperature.

The electronics 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.
