Ship 4-20mA Pressure Transmitter
Our DC 4-20mA Ship Pressure Transmitter is an industrially robust, high-performance sensor engineered specifically for marine and offshore applications. It delivers reliable, continuous pressure monitoring by converting mechanical pressure into a standardized, noise-resistant 4-20mA electrical signal. This two-wire loop-powered transmitter is the ideal solution for vessel pressure monitoring, shipboard system control, and integration with PLCs and SCADA systems, ensuring operational safety and efficiency in the most demanding conditions.
How It Works: Reliable & Accurate Signal Transmission
-
Precision Sensing: A advanced piezoresistive sensor core detects applied pressure, translating it into a minute electrical signal.
-
Intelligent Signal Conditioning: Onboard circuitry amplifies, linearizes, and temperature-compensates the raw signal, ensuring high accuracy and long-term stability.
-
Standardized Output: The conditioned signal is output as a stable 4-20mA DC current, where 4mA represents the zero or minimum scale (e.g., 0 MPa) and 20mA represents the full-scale pressure (e.g., 60 MPa). This industry-standard signal is ideal for long-distance transmission with minimal signal loss.
