The Riken Keiki RX-515, RX-516, RX-517 marine portable combination gas detectors are specially designed and developed for marine applications. When loading tanks are flushed with inert gases, the O2 content drops proportionally to some inert gases used. Catalytic EX sensors need a minimum content of oxygen in the sample gas to be able to measure combustible gases correctly. As this minimum content is not available, instruments with catalytic sensors are not suitable for conducting EX measurements in inert atmospheres. A solution to this problem is to use infrared technology sensors (NDIR). Infrared sensors measure concentrations of combustible gases reliably, even if O2 is not present. With the Riken Keiki RX-515, RX-516 or RX-517 and, its NDIR sensor you are well suited for this kind of application.

Based on patented digital signal processing technology, the SIEMENS SITRANS FCT030 transmitter delivers true multi-parameter measurements with enhanced efficiency, security and simplicity. It features a modular design for convenient installation and replacement and can be remote or compact mounted with all SITRANS FCS400 sensor sizes. The SIEMENS SITARSN FCT030 is approved for custody transfer and certified for safety-critical applications up to SIL level 3. It is a universal transmitter suitable for all industries certified for hazardous areas with ATEX, IEC Ex and FM approvals. The transmitter is based on the latest developments within digital signal processing technology “ engineered for high measuring performance: Fast response to step changes in flow Fast dosing applications Entrained gas High immunity against process noise High turndown Easy to install commission and maintain The FCT030 transmitter is available as standard with 4-20 mA analogue output with HART 7.2. Additional input/output functions can be freely configured for analogue, pulse, frequency, relay or status. The transmitter comes with a user-configurable graphical display and new SensorFlash® technology, a micro SD card for configuration backup, firmware update and data storage. In order to make a complete flowmeter system, the SITRANS FCT030 transmitter must be combined with the sensor SITRANS FCS400.

The SIEMENS SITRANS FCT010 is a tiny yet powerful Coriolis flow transmitter, developed especially for direct digital integration into process automation systems. Its compact design without display combined with its capability for digital output signals make it a perfect choice for skids and other applications where space is limited.
