Wireless Deadman & Transmission

Ship and Shore is able to offer some very robust "of the shelf" Sec-tech solutions to some simple issues facing operators when transfering liquid cargoes.

Secu-data - Hazardous location wireless transmission of measurement data
The components of the new SECU-DATA product line make use of latest technologies for the transmission of measurement data via radio frequency connections in the 433 MHz band for various fields of applications:
Wireless transmission of 4-20 mA signals from a measurement location to the control centre, typical applications are industrial process automisation, evaluation of all kinds of 4-20 mA sensors for temperature, humidity, filling level etc. in the chemical industry.

Wide fields of applications exist for remote transfer of liquid levels of all tank probes in common use to a centralised control station, integration of overfill prevention systems into fuelling systems for automotive fuelling, harbour terminals, railway tankers and aeroplane fuelling systems.

Special “barriers“ providing high current output capability and stable output voltage open manifold applications in the hazardous, flammable, explosive environments

The main advantages of data transmission using Secu-data are:

  • Transfer of measurement data from explosive areas (Ex-zones) to safe areas without galvanic connections
  • Protection class IP68 for outdoor applications
  • No wiring, no ground loops
  • [Ex ia] IIC T4
  • Quick installation without digging
  • Highest reliability of the RF-connection due to high noise rejection with automatic channel selection

Applications for SECU-DATA 4xxx

  • All practical applications where 4-20 mA measurement signals have to be transmitted and where wiring is not feasible.
  • Temporary measurement data transmission for verification of fixed installed sensors, for this application the high accuracy of the 16-bit resolution is highly useful.
  • Measurement data acquisition on mobile tanks, where wiring is not feasible. Remote monitoring of gauge sensors, limit switches.

 

 

 

 

 

 

 

 

Secu-tech Wireless Deadman and Emergency Stop for Hazardous Areas

Use your existing overfill probes to provide an emergency stop signal to a pump or valve system without cables accross jetties or between each end of the fluid transfer. With Secu-tech LRC remote control you can monitor the situation with a hand held, battery powered device which also doubles as a deadman. Widely used in Europe to make ship to shore transfers "fail safe", there are many possibilities for Secu-tech's LRC Remote control.

The Secu-tech LRC is available in two basic configurations:

  • LRC-Small ADN (photo on left) which is plugged directly into a connection on board the ship. The remote control continuously sends a signal to the pump which is being used to transfer the liquid, ie. a normally closed circuit is held open.
  • LRC-Small Remote which is an additional remote that can be used to start and stop the pumping operation, reduce or increase RPM of the pump, roll the hose in or out or customer defined action.
