ULTIMA XE/ULTIMA X3The ULTIMA XE series of gas monitors is available with catalytic sensors for combustible gas and electrochemical sensors for toxic and oxygen.
All ULTIMA X series monitors are protected by a rugged, explosion proof stainless steel enclosure and are suitable for indoor and outdoor applications in virtually any industry including offshore operations.
The monitors can be deployed as stand-alone units, but also provide a 4 to 20 mA output for connection to controllers.
Allowing for variable sensor placement, ULTIMA X series gas monitors have multiple enclosure entries for left, right or bottom wiring. The monitors are also suitable for remote sensing applications, with up to 15 m between sensor and electronics.
The modular design allows for pre-installation and wiring of the main enclosure at early stages of site construction. Main electronics and calibrated sensors can be easily added at commissioning to reduce risk of loss or damage and maximise sensor life.
ULTIMA X catalytic and toxic “Smart Sensor” modules store all calibration data internally, allowing convenient sensor presetting and calibration in the workshop. Calibration in the field is also possible, e.g. if required by regulations. No tools are needed for connecting or disconnecting sensor modules, and power to the monitor can remain on.
ULTIMA X3 Technology
The ULTIMA X3 has all the benefits of the ULTIMA X series and is also capable of digital communication. A maximum of 31 ULTIMA X3 transmitters can be connected to the same line via ModBUS RTU. Since ULTIMA X3 units can be equipped with up to 3 sensors each, 93 sensors in all can share a single signal line. The wiring effort is minimal.
[Multi-Sensing System] - Various combinations of electrochemical, catalytic and infrared sensors available
- Remote diagnostics feasible thanks to sensor condition transmissions
- Gas monitor’s “scrolling display” shows all its sensor types
- ULTIMA X3 monitor operates as slave device on the network
- Optional remote sensor installation allows for a maximum distance of 15 m for each sensor
- Internal relays can be configured for 3 different common alarms or one individual alarm for each sensor
