Q45CT Toroidal Conductivity Transmitter
Loop-Powered or Battery-Powered Transmitters
ATI’s Toroidal Conductivity Transmitter is designed for on-line water quality monitoring of chemically aggressive process solutions. This sensor consists of two metallic ribbon coils that are fixed in place by the sensor jacket material. The drive coil is used to induce a current in the process solution. The second sensing coil is used to measure the current in the process solution, the magnitude of this current is proportional to the conductivity of the process solution.
The Q45CT is also available as a Concentration Monitor. The conductivity monitor comes with concentration/temperature tables for sodium hydroxide, potassium hydroxide, hydrochloric acid, nitric acid, and sulfuric acid. A user configurable table is also available for entering data points for a custom concentration curve.
This system is well suited for aggressive chemical processes, water application that coat or foul traditional sensors, and plating bath operations where high current densities are present.
Adaptability
Concentration version for direct display of chemical concentrations.
Extra Outputs
Expansion board to add a third 4-20 mA analog output or to add three additional non-isolated low power relays.
Flexibility
Wide range capability, with selectable ranges of 0-200.0 uS up to 0-2.000 S provide maximum application flexibility.
AC or DC Power Options
Power options include universal 100-240 VAC +/- 10%, or 12-24 VDC.
Flexibility
Programmable range options from 0-200 PPB up to 0-200 PPM provide maximum application flexibility.
AC or DC Power Options
Power options include universal 90-260 VAC or 12-24 VDC.
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.
PID Output
Standard PID control function assignable to one analog output.
Digital Communications
Available in either Profibus-DP, Modbus-RTU or Ethernet-IP.
Relay Assignable
Three SPDT relays are standard, with relay functions programmable for alarm, control, or trouble indication. Three additional low power relays available as an option.
Flexible Mounting
NEMA 4X (IP-66) enclosure is suitable for wall, pipe, or panel mounting.
Clear Display
Back-lit large LCD display provides clear visibility in any lighting conditions. A scrolling second line on the display provides additional information and programming prompts.
