Intrinsically safe Trafag Ex-pressure transmitter EXNT 8292
Robust pressure transmitter with long term stability for hazardous areas
The new Ex-Pressure Transmitter EXNT by Swiss manufacturer Trafag was developed for relative pressure measurement in explosion endangered areas such as in the oil and gas industry as well as the mining industry.Bubikon, April 2013 - The new Ex-Pressure Transmitter EXNT type
8292 was developed to fulfill the norms according to ATEX and IECEx for the application in the Ex-zones with gas contact 0, 1, 2, dust contact 20, 21, 22 as well as the application in underground mining. (II 1G Exia IIC T4/T6 Ga, II 1 D Ex ia IIIC IP6x T130° Da, I M1 Ex ia I Ma, II 1/2G Ex ia IIC T4/T6 Ga/Gb). It additionally fulfills the EMC protection according to IEC61000.
The technical advantages of the Ex-Pressure Transmitter EXNT type
8292 is the wide pressure measuring range 0…400 mbar to 0…2000
bar, a very high burst pressure safety (up to 3x of the nominal pressure) as well as an excellent long-term stability thanks to its thin-filmon-steel sensor technology.
The sensor system is completely welded and is therefore absolutely gas tight. The Ex-Pressure Transmitter EXNT has an output signal of 4…20 mA and is available with accuracies of
0.1% and 0.3%. Various pressure connections and electrical plugs, a protection up to IP67 as well as the large range of permitted operating temperatures from -40°C up to 120°C enables nstallation in many varied areas.
