The PL3700X is a family of pressure sensors which fulfill virtually all of the pressure and level sensing needs aboard a ship. They come in a variety of sensing ranges, materials, adaptation types and fittings
What Is It?
The PL3700X transmitters are typically used to measure the level and temperature of service tanks, ballast tanks and water tanks, as well as pressure of all pipes, atmospheric, draft, inert gas, etc. The PL3700X’s transducer can be immersed and mounted inside the tank using the adaptor bracket or for side mounting using the adaptor flange.
The PL3700X sensor features a fully digital, temperature compensated circuit, which eliminates the need for periodic adjustment. Thanks to its intrinsic safety and HART communications, the PL3700X transducer can be operated, diagnosed or re-ranged in hazardous areas. The PL3700X mechanical and chemical design are optimized for the best compatibility with the ballast water treatment systems made compulsory by the Ballast Water Treatment directive, ensuring a long lifetime of safe and reliable operations. Special models are available for atmospheric pressure measurement (ATMO) and for cargo line pressure measurement (MAN).
How Does It Work?
The PL3700X transmitters are built around a proprietary ceramic sensor. This provides excellent and stable accuracy, even after years in difficult conditions. The self-contained sensor sends a 4-20 mA HART signal to the ship system. This allows easy calibration and maintenance on deck. The transmitter bodies are available in stainless steel or special composite.
