SUBSEA SYSTEM ANALYSIS & DATA MONITORING EQUIPMENT

  • Supply Voltage: 9-28Vdc
  • Maximum Input Current: 100mA
  • Scaling Range - Span: 0-2000
  • Scaling Range – Offset: -1999 – 1999
  • Storage Temperature: -40 – 80 ⁰C
  • Operating Temperature: 0 – 60 ⁰C
  • Maximum Voltage Drop: 3.2Vdc
  • Equivalent Resistance: 800Ω Max @ 4mA, 160Ω Max @20mA
  • Display: 3 ½ digit 0.6”
  • Sensor Display: Pre-set to 0-100%, 4-20mA or sensor range

J+S is developing a range of monitoring equipment to provide our clients with solutions to identify subsea issues. This range of basic tools are designed to assist intervention operations by providing immediate and local display of sensor outputs or basic system parameters. This range is adaptable to allow connection to any system and standard port interfaces enable the option of penetrators to cable or oil filled hose assemblies either side for ease of installation. This range can also be expanded to meet any new requirements identified.

Display 420

The Display 420 is a basic display which provides local indication of a 4-20mA signal. Designed for installation and retrieval by diver, the display is loop powered so there is no need to provide a separate power supply or battery.

Display Specification

  • Supply Voltage: 9-28Vdc
  • Maximum Input Current: 100mA
  • Scaling Range - Span: 0-2000
  • Scaling Range – Offset: -1999 – 1999
  • Storage Temperature: -40 – 80 ⁰C
  • Operating Temperature: 0 – 60 ⁰C
  • Maximum Voltage Drop: 3.2Vdc
  • Equivalent Resistance: 800Ω Max @ 4mA, 160Ω Max @20mA
  • Display: 3 ½ digit 0.6”
  • Sensor Display: Pre-set to 0-100%, 4-20mA or sensor range

Display VA

The Display VA is a subsea In-line Voltage & Current display. This will provide a local indication of Voltage and Current. The unit can also be installed directly onto the end of a test downline enabling Divers to see directly whether the line is powered during intervention operations.

Simulator 420

The Simulator 420 utilises the same simple 0-100% display but with the addition of a loop powered 4-20mA simulator and rotary switch. This is designed to be connected between the Subsea Control Module (SCM) and the sensor. It is then used to either display the output signal from the sensor output or inject a set range of simulation signals to test the SCM’s operation.

Simulator Specification:

  • Supply Voltage: 12-28Vdc
  • Output Range: 9-28Vdc
  • Fixed Pre-set: 9-28Vdc
  • Output Accuracy: +/- 1% of full scale @ 25⁰C
  • Protection: Reverse Polarity
  • Load Range: 0-1000 Ω (250 Ω typical)

Data 420 / DataCAN

The Data420 or DataCAN are subsea In-line data loggers that include a retrievable data memory module recording 4-20mA or CANBus data. This unit can be left connected in-line and the memory module retrieved and replaced when required.
