The initial set-up included several single function signal conditioning modules. Single function transmitters are designed for specific tasks. If they fail when the ship is at sea, and the staff does not have a replacement in stock, getting a replacement from shore can often be both time consuming and costly. The company had experienced this issue on several occasions in the past. The company wanted a solution that included a more universal transmitter covering a wide range of applications – and with the approvals, in this case either DNV or GL, to be used at sea. A specialist suggested a universal transmitter like DRST-UN or DRST-UR to the project team. The transmitter is multi-functional – has a universal AC or DC power supply, offers high galvanic isolation and high EMC immunity, can measure almost any analog or temperature signal, and provides output for current and voltage, which are typical output signals in marine applications. In addition, the transmitter is designed according to strict safety requirements, including UL, FM, DNV, and SIL.
Putting the Standard to the Test The project team agreed to test the transmitter. The test showed that the transmitter fulfilled the requirements:
- The device covered all the needed applications
- The device had the right approvals
- The device was easy to use both in relation to mounting and programming
- The device has a 5 year warranty
New Site Standard The transmitter passed the test, was specified for the project and was selected as new site standard. The company has subsequently experienced smoother operation and been able to save on spare parts inventory.
