Description

Model PT605 on stream monitor / analyzer has been designed for the detection of Carbon Dioxide in Process Streams and Natural Gas Pipeline.  The system is cost effective yet highly accurate and reliable.  An industry standard 4-20mA output and three programmable alarm relay contacts are provided.  These relay contacts can be used to control shut in valves. A large LCD display with back light and push button switches on the front panel are provided for easy user interface calibration.

Also available are real time clock and non-volatile memory for historical data logging. The unit is MODBUS RTU serial communication compatible with PLC’s, SCADA, and DCS systems.  PT605 Analyzer provides complete status like current gas concentration, last successful calibration date & time and current alarm status via MODBUS link. The alarm levels can also be accessed and programmed via MODBUS.
