Q46/76 Turbidity Monitor
Q46T monitors also provide sensor diagnostic functions to warn of condition that cause inaccurate or invalid readings. The sensor is continuously monitored for optical fouling, and will display an alarm message when the sensor requires cleaning In addition, the sensor will detect the lack of water in the flowcell and provide a “dry cell” when an air interface is detected. These alarm conditions will cause a third alarm relay to activate, which can be used to indicate these conditions remotely.
Power options include universal 100-240 VAC +/- 10%, or 12-24 VDC.
Wide range capability, with selectable ranges of 0-2.000, 0-20.00, 0-200.0 and 2000 NTU provide maximum application flexibility.
Two isolated 4-20 mA outputs are standard, with an option for a third output if required. Default setting provides analog outputs for turbidity and temperature.
Standard PID control function assignable to one analog output.
Communication options for Profibus-DP, Modbus-RTU, Modbus-TCP/IP or Ethernet-IP.
Three SPDT relays are standard, with relay functions programmable for alarm, control, or trouble indication. Three additional low power relays available as an option.
NEMA 4X (IP-66) enclosure is suitable for wall, pipe, or panel mounting.
Back-lit large LCD display provides clear visibility in any lighting condition. A scrolling second line on the display provides additional information and programming prompts.
System automatically checks for sensor fouling, “dry cell”, and external light interference.
