Subseapressure sensors

Highly accurate pressure measurement in harsh dredging and subsea environments


Subsea pressure sensor range designed to endure harsh operating conditions

The Pressit® underwater pressure sensor range serves the dredging and maritime industry as accurate and high-performance device for reliable and long-term (subsea) use. As is required for dredging applications, the pressure sensor was designed to last in a context of rough operations. Its level of endurance is achieved by the corrosion- and abrasion-resistant capacitive sensor with rugged ceramic measuring diaphragm, which offers high peak overload protection. Water hammer effects and pressure surges cannot damage the ceramic sensor diaphragm.

Our subsea pressure transducers come in a wide variety of models. In addition to the most popular range which is illustrated below, we are able to supply virtually any underwater pressure sensor, adapted to your case and requirements. Next to the delivery of stand-alone sensors, Seatools supplies full-fledged subsea monitoring systems, which include all related sub-systems: mechanics, software, electronics, controls, and more.

  • Pressit® subsea pressure sensors can be applied to a wide range of dredging, offshore, and subsea equipment, such as dredging suction pipes, dredging pumps, ROVs, vessels, and pontoons.

We consult clients during their selection process to ensure they opt for the right pressure sensor. In our recommendation, we take into consideration pressure ranges, required accuracy, system setup, data communication, mounting possibilities, vibrations, and other factors that are relevant to your situation.

Key Features

  1. Robust design

    Pressit® subsea pressure transmitters are able to withstand the most severe of conditions, such as shock loads and vibrations during dredging operations. Their rugged ceramic measuring diaphragm, furthermore, offers high peak overload protection.

  2. Highly accurate

    Enabling for very high system accuracies, Pressit® subsea pressure transmitters have been applied to subsea monitoring systems at many occasions.

  3. Highly customizable

    All Pressit® subsea pressure transmitters can be configured to suit your application and meet your requirements. This shows from the fact that as many as 31 different configurations have been delivered to date. Adjustments can be made with variations in pressure ranges, data communication, mounting options, accuracies, and factory testing and qualification programs.
