Model Q46C2 2E - Conductivity Monitor
From Water Monitors
Low-level conductivity measurements are essential for a variety of water quality monitoring. The proper operation of deionizers, reverse osmosis membranes, ion exchange systems, and heat exchangers require constant monitoring to ensure high quality production. ATI’s Model Q46C2 Conductivity Monitor provides the reliable and accurate low-level water quality measurements required for such high purity water systems. Monitors provide large, easy-to-read LCD displays with a second display line for indication of temperature or other operational information. And for those applications where results in resistivity units are preferred, Q46C2 monitors can be programmed to display readings in Meg-ohm units instead of microSiemens.
Q46C2 conductivity monitors can also be configured to measure and display the concentration of chemicals used in various process applications. The user defined concentration table requires data on both concentration vs. conductivity and temperature vs. conductivity for the chemical of interest. The user can enter six data points each for concentration and conductivity within the specified measuring range. Temperature compensation can either be made by custom compensation table or a single linear compensation factor.
For applications where there are several chemicals dissolved in solution, the Q46C2 monitor can be configured to measure and display the concentration of total dissolved solids (TDS). The user simply enters the TDS factor that best converts the process conductivity into concentration units. Temperature compensation can either be made by custom compensation table or a single linear compensation factor.
Concentration version for direct display of chemical concentrations. Also available in a TDS (Total Dissolved Solids) version.
A user configurable table for a custom concentration curve is available.
Analog Output Options
Two isolated 4-20 mA outputs are standard, with an option for a third output if required. Default setting provides analog outputs for conductivity and temperature.
Expansion board to add a third 4-20 mA analog output
AC or DC Power Options
Power options include universal 100-240 VAC +/- 10% or 12-24 VDC.
Standard PID control function assignable to one analog output.
Communication options for Profibus-DP, Modbus-RTU, 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.
