Analyzer is calibrated in the background gas of the process.
Standard gases are: N2, CO2, CH4, H2 & Biogas. Others available
on request.
2 off 4-20 mA inputs
One for an external sensor that can be displayed on the screen
One to act as an active compensation for the process conditions
2 off 4-20 mA outputs (powered with 24V excitation voltage)
Primary range is set to the calibrated range of the instrument
The second is user selectable 0-100%
2 off single pole changeover (SPCO) relays for O
(250 V, 5 A max)
The user can use the digital communications to log the output
from the analyzer
The unit will store 40 alarm points and the min/max O
concentrations with date and time stamp
Modbus RTU over RS485 Protocol
24 V DC; 1.5 A max
Analyzer is supplied with 3 x M20 cable entries. Cable glands,
conduit entries and blanking plugs are available as accessories.
