N-JB pressure transmitter works in the medium that can have inflammable dust or methane exposure, like in mines. Its I M1 Ex ia I and II1G Ex ia IIB T4 Ga versions have been approved by a laboratory that is accredited. Nominal pressure range is ± 100Pa to ± 100kPa, overpressure to 2kPa is 20 kPa, overpressure from 2kPa to 20 kPa is 50 kPa, overpressure from 20kPa to 100 kPa has a 300 % nominal range and overpresure over 100 kPa has a 200 % nominal range. Its operating temperature range is -20°C to +60°C while the storage temperature is from -25°C to 100°C. Its supply voltage output F,G is 10 to 22V dc, output H is 8.5 to 22V dc. Its supply current output G,H is 4.5 mA. The transmitter has the protection level of IP 65 minimum and it weighs 400g.
