*Optima Plus XTC Gas Detector, includes polyester mesh dust barrier, nylon weather protection housing and LNP Faradex deluge/sunshade 


Optima Plus is a Zone 1 hazardous location-certified flammable infrared gas detector. Infrared gas detectors are ideal suited for applications where the detector is exposed to harsh environmental conditions or where catalytic poisons are routinely present.


Optima Plus combines excellent speed of response, unsurpassed reliability and simple routine maintenance. Two base versions are available; hydrocarbon andethylene units between them covering a wide range of detectable hydrocarbons, including solvents. Optima Plus carries internationally recognised approvals for both hazardous locations and performance, including European (ATEX), international (IECEx), North America (UL), Canada (CSA and FM), Marine (MED, BV, DNV, Lloyds and ABS) and Russia (Eurasian Customs Union). Additionally Optima Plus has been approved to SIL2 by renowned certification body T?V Rheinland.


Optima Plus is available with HART? over 4-20mA output and is registered with the HART? Communication Foundation. This communication protocol delivers enhanced diagnostic information either local to the detector using the optional OELD smart junction box or back at the control room. The information provided can be used to better plan and execute maintenance operations.


The Optima Excel Local Display (OELD) is a smart junction box for the Searchpoint Optima Plus and Searchline Excel infrared detectors for flammable hydrocarbons. Please refer to the chapter 26 for the OELD (Optima Excel Local Display).


Various termination units are offered for use with the Optima Plus and need to be ordered separately. These provide a range of mounting and field wiring options ranging from standard Ex e termination units, through to the UL-approved DX100 termination unit and the XNX Universal Transmitter. For the direct connection to the Optima system using the SHC-1 handheld interrogator, the SHC protection device module must be used. Other accessories include Duct Mounting kits, Sunshades/Deluge Protections, Storm Baffles and Gassing Caps.


A full range of optional accessories are available for use with the Optima Plus gas detector, including junction boxes, duct mounting kits, test and calibration accessories, hazardous location-approved plastic storm baffle. All detectors are supplied with the accessories indicated together with a printed quick start guide and CD-ROM.
