Overview

The Dawan DW11 series pressure gauge detector is a high-precision pressure measuring instrument designed specifically for marine environments. It adopts a compact titanium alloy structure and is suitable for observation platforms such as profile measurement chains, fixed depth water harvesters, and submersibles. The product offers two versions: direct reading and self-contained, to meet the measurement needs in different scenarios. The $r $n direct reading device requires an external DC power supply or adapter to be used, and can be used with cables to transmit data back to the computer and view the data in real time. If the user selects a handheld terminal, the above functions can be achieved without power or computer. In addition, direct reading devices support access to data collection systems to meet user integration needs

Product Details

The Dawan DW11 series pressure gauge is a high-precision pressure measuring instrument designed specifically for marine environments. It adopts a compact titanium alloy structure and is suitable for observation platforms such as profile measurement chains, depth water harvesters, and submersibles. The product offers two versions: direct reading and self-contained, to meet the measurement needs in different scenarios.

Direct reading devices require an external DC power supply or adapter to be used, and with cables, data can be transmitted back to the computer and viewed in real-time. If the user selects a handheld terminal, the above functions can be achieved without power or computer. In addition, direct reading devices support access to data collection systems to meet user integration needs.

Self contained devices come with built-in batteries and storage, eliminating the need for an external power source. Users only need to connect communication cables to view real-time data. This device also supports independent operation without cables, independently completing power supply, measurement, recording, and storage. After the device is recovered, the measurement results can be exported through the data interface.

Product advantages:

precision measurementHigh accuracy, high resolution, high stability, low power consumption

Easy to useThe operation interface is simple and easy to use, convenient for integration with other instruments or platforms, and can be equipped with handheld terminals

service capabilityCore technology is independently controllable, providing fast after-sales response, remote guidance, calibration services, etc
