Level TOTAL CARGO MEASUREMENT AND MONITORING SYSTEM FOR MARINE APPLICATIONSTA840 RADAR MONITORING SYSTEM

TA840 RADAR MONITORING SYSTEM

TA840 RADAR MONITORING SYSTEM PDF

*Specifications are subject to change without prior notice.

This monitoring system consists the radar level gauge TA840,cargo temperature and inert gas pressure transmitter I-NODE, intrinsically safe power supply IS-POWER M1, control module CONTROL M1.
This system communicates with Multi-monitor SuperDIR series to measure and monitor each cargo level, temperature and pressure.
This system is suitable for measurement and control of liquid cargos at crude oil tankers and product/chemical carriers.
TA840 radar level gauge has been in operation for over 15 years and more than 6,000 units are installed on board all kind of ships and platforms.
Offering the latest upgraded version and ensuring the required stability and reliability of the cargo measurement and monitoring system.

Features

  • · TA840 radar level gauge is a stand-alone radar type level transmitter using a frequency modulated continuous wave (FMCW) that can measure the level of liquid cargo without being affected by the temperature and viscosity change of the liquid cargo.
  • · TA840 radar level gauge can be compatible with the cargo temperature (max.3points)and inert gas pressure data by connecting the I-NODE on the same power & communication lines to cargo control room, thus saving wiring.
  • · IS-POWER M1 intrinsically safe power supply provides RS-485 isolator/barrier to meet the intrinsic safety requirements and its outputs is extremely stable, thus ensuring the best performance and longevity of the equipments which are connected.
  • · CONTROL M1 control module is a flexible control unit which provides I/O and network interfaces.
    It comes with a unique feature that brings plug and play capability to all the equipments which are connected.
  • · This system is suitable for retrofitting of existing TA840 radar system as it has the compatibility with old TA840 radar system.
