Marine Pressure Transmitter (YSZK) | 4-20mA Output

Technical Specifications：

Key Features：

• High-Accuracy Sensor: Utilizes a diffusion silicon sensor to achieve a measurement accuracy of ±0.5% FS.
• Standard 4-20mA Output: Provides an industry-standard 2-wire, 4-20mA signal for easy integration.
• Compact & Direct Installation: The small body and standard thread connections (M20x1.5, G1/4″, G1/2″) allow for simple installation.
  
• Designed for Marine Use: The unit is built to resist the vibration and shock common in shipboard engine rooms.

Applications：

• Fuel Oil Systems: Measures pressure in fuel supply and return lines for engines and boilers.
• Lube Oil Systems: Monitors lubricating oil pressure for main engines, generators, and gearboxes.
• Freshwater & Seawater Systems: Gauges pressure in cooling circuits, hydrophore systems, and general service lines.
• Compressed Air Systems: Monitors pressure in engine starting air lines and service air systems.

Installation & Maintenance：

Installation: Install the transmitter onto the corresponding threaded port in the pipe or on the equipment. Use a suitable sealant for the threads. Connect the two wires to the control system.
Maintenance: The unit is sealed and requires no regular maintenance. Periodically check the electrical connections and ensure the unit is free from external damage.

Need something specific?

We can provide transmitters with different pressure ranges, other thread standards, and required classification society certificates (CCS, DNV, etc.).

FAQ ：

Q: What is a 2-wire system?

A: A 2-wire system means the transmitter is powered by the same two wires that it uses to send the 4-20mA signal. This simplifies wiring.

Q: Is this suitable for measuring seawater pressure?

A: Yes, with the appropriate housing and sensor material selected. Please specify the medium when ordering.
