Details

The APG PT-500 submersible pressure transducer is designed for use in a wide variety of environmental monitoring applications. The sensor is ideally suited for measuring water level in weirs, flumes, small to large streams, ponds, lakes, irrigation channels, and groundwater wells. The sensor is installed in a fixed location below the minimum expected water level, and a cable containing the sensor signals and vent tube is connected to a data logger mounted above flood stage.

The PT-500 measures the combined pressure exerted on it by the atmosphere and the head of water above it. A vent tube in the cable automatically corrects for changes in barometric pressure, and measured values are mathematically compensated for all linearity and temperature errors. With +/-0.1% Full Scale accuracy, the PT-500 provides high performance and accuracy over a wide range of operating conditions. The housing is constructed with laser welded 316L stainless steel.
