Specifications

HS CODE 8428900000

General

The I.M.C system continuously measures liquid level and temperature, as well as inert gas pressure in the cargo tanks. This system is based on a DISTRIBUTED DATA PROCESSING ARCHITECTURE. using the stand alone TA840 contactless level transmitter installed on the top of each tank, and connected to the TA840-I safety module located in the cargo control room. The associated inert gas pressure and liquid temperature information is transmitter to the cargo control room by means of the pressure and temp. sensor directly connected to the TA840.

Principle of Operation

The TA840 is a stand alone RADAR TYPE level transmitter using a frequency modulated continuous wave (FMCW) electromagnetic signal to measure the distance between its antenna and the cargo tank content surface (ullage).

The difference between the emitted and reflected FMCW signals is directly proportional to the ullage. An adapted data processing is then able to be calculated. The micro wave signal issued from the antenna is directly processed by the dedicated processor inside the TA840. so that the output signal sent to the cargo control room is directly the digital value in MM of the measured ullage. RS485 digital link is used between each TA840 and the TA840-I safety module in the cargo control room.

I.M.C - Innovative Measuring Concept (I.M.C)

DEVELOPED IN COOPERATION WITH THOMSON-CSF

Features

  • The principle of the TA840 RADAR SENSOR is the utilization of an intrinsically safe low-power processor unit which analyses the antenna signal and converts the information into digital values.
  • The TA840 RADAR SENSOR is a totally sealed unit with a standard RS485 field bus output signal.
  • For simplicity of installation the TA840 RADAR SENSOR requires only two cable inputs and is connected to a safety module which includes individual channel zener barriers.
  • The TA840 RADAR SENSOR incorporates and auto-control facility for continuous performance monitoring.
  • The TA840 RADAR SENSOR is provided with a simple pivot hinge arrangement to enable the cleaning of the antenna emission face without needing separate cleaning hatches.

Advantage

  • Simple and quick installation.
  • Reduced cabling cost with integrated temp. and I.G.pressure measurement.
  • Easy commissioning through "COMMINC" mate software with automatic radar self test at power up.
  • Standardized communication protocol RS485 data link for direct connection with:
    ECOS, Norcontrol, Praxis, Samsung, etc.
  • Integration of other supplier device.
  • Self-diagnostic and remote configuring automatic antenna fouling detection.
  • Proven accuracy: ±1mm

Oil Detector on the Tank

General

Boiler feed filter tank have a inspection chamber or devide area in tank to accumulate oil when oil contamination on boiler water.
When incoming oil contaminated water in inspection chamber, the feed water only go out to feed filter tank and oil with be accumulate in inspection chamber until drainage.
When the normal conditions, the end part of electrode will be in water level always.
But the water contaminate oil that the oil is accumulate top level in inspection chamber, the electrode will be in oil level instead of water level. The oil detector will activate alarm.
After drain oil in inspection chamber, the oil detector return to normal condition.
