APT 500 Series Marine Liquid Level and Pressure Transmitter

The advanced MEMS piezo sensor integrated into the APT 500 provides high accuracy, with excellent repeatability and long-term stability. The sensor is fully temperature compensated to remove any thermally introdued errors between 0 to 70°C. 

The sensor body is an all welded construction suitable for continuous submersion and is offered in a choice of corrosion resistant materials to ensure compatibility with all shipboard fluids.

A choice of mounting options and adapters provide complete installation flexibility. A factory sealed cable is supplied with a heavy-duty outer sheath of cross-linked polymers, suitable for continuous immersion in seawater, fuels and hydrocarbons.

The APT 500 is supplied factory calibrated to the users requirements and can be specified with calibration from 1 Metre WG to 40 Bar. Both Gauge pressure and Absolute pressure versions are offered.
