Pressure Sensor and Transmitter for Marine System Application

Date: 2022-Mar-31

MicroSensor Products

A ship has a huge control system, including an engine control system, rudder control system, refrigeration system, equipment condition monitoring, and pre-maintenance system, marine starting system, waveguide radar system, launcher control system, etc., and this article is about the pressure sensor and pressure transmitters for marine system application.


A ship is a vehicle capable of sailing or berthing in waters for transportation or operation. The ship has a huge control system, including an engine control system, rudder control system, refrigeration system, equipment condition monitoring and pre-maintenance system, marine starting system, and waveguide radar system, launcher control system, etc. Different control systems and marine high- and low-pressure air compressors, fire water pipe level underwater equipment all have different requirements for pressure and level measurement.

The rugged and accurate measurement of each pressure sensor and pressure transmitter provides the necessary data and output for system applications to increase efficiency, reduce energy consumption, and accurate positioning. In addition, pressure measurement in terms of equipment condition detection and early warning also provides basic data support for the reliability and failure rate of ship systems.

Pressure Sensor and Transmitter for Marine System Application

Marine System Application

Pressure transducers and transmitters are widely used in marine systems, and their applications are classified into two categories, as follows:

Part I: Measurement of Power Systems

Measurements of ship power systems include ship engines, ship cabin control systems, refrigeration systems, and desalination systems.

Measurement of Power Systems

Part II: Measurement of Water Level Depth

The key performance is the measurement of the water level of the underwater diving equipment during operation. The crew can perform subsequent control and related operations based on measurement and judgment of the water level depth.

At present, our pressure sensors and transmitters have a series of product certifications in the domestic and foreign marine industries, mainly in CCS (China Classification Society) and DNV.

Micro Sensor has a large number of customers and application examples in the marine industry for long-term use. At the same time, there are a long-term bulk supply of model projects for more than 15 years in underwater equipment and have won great reputations.


The marine field is an important strategic field. The development of its technology also represents progress. The development of marine equipment technology and equipment performance depends on the performance of the sensors used in the ocean. Focusing on the development of sensor technology is the key to improving the performance of ships.

Micro Sensor has long been engaged in the research and design of related projects in the deep ocean and marine fields. In the future, we will invest more resources in the research and development of pressure transmitters in the marine industry to contribute to the marine industry.
