Atmospheric pressure sensor for ambient pressure measurement in marine applications, on board a ship and in the engine room. This version of the DMP 457 marine approved pressure sensor has a 4-20mA current output scaled over the atmospheric pressure range of 800 to 1200 millibar absolute.
The DMP 457 marine approved pressure sensor is specifically designed for atmospheric pressure measurement in marine environments. This robust sensor is ideal for use on board ships, including challenging locations like the engine room. It provides crucial atmospheric pressure data for various applications, including engine performance optimization, weather monitoring, and HVAC system control.
A key feature of this sensor is its 4-20mA current output, which is scaled across the typical atmospheric pressure range of 800 to 1200 millibar absolute. This standardized output signal allows for easy integration with existing shipboard monitoring and control systems, simplifying installation and data acquisition. The 4-20mA output also offers good noise immunity, ensuring reliable signal transmission even in environments with electrical interference.
The DMP 457 is engineered to withstand the harsh conditions encountered in marine applications. It is built with marine-grade materials that resist corrosion from saltwater and humidity. The sensor is also designed to tolerate vibrations and shocks commonly experienced on ships, ensuring long-term reliability and performance.
This atmospheric pressure sensor is suitable for a wide range of vessel types, including cargo ships, tankers, passenger ferries, and offshore platforms. By providing accurate and reliable atmospheric pressure measurements, the DMP 457 contributes to efficient and safe operation in demanding marine environments.
