BC9 SeriesElectrodeless Conductivity Controllers Features • IP66 surface mounting enclosure • Low cost maintenance free system • Cooling tower bleed and proportional feed • Solution concentration with optional 0-5% NaOH range • Rinse water control The BC9 series of electrodeless conductivity controllers are designed for use in applications where sensor fouling occurs. The electrodeless or inductive method of measuring conductivity provides a maintenance free measurement system at a competitive price when using the BC9 series controllers with the LTH Electronics ECS/20 series of electrodeless conductivity sensors. The controllers are housed in an IP66 surface mounting enclosure with a 3.5 digit LCD display. Four measurement ranges can be selected: - 1.999 mS/cm, 19.99 mS/cm, 199.9 mS/cm & 1999 mS/cm. Note that 1.999 mS/cm = 1999 pS/cm. An optional version is available with the output scaled 0-5% NaOH (Sodium Hydroxide). The BC9 series comprises of four models as follows: The BC9 has a single changeover relay, with a fully adjustable high or low control set point that can be used for a variety of dosing and bleeding applications. The BC92 has a second relay that gives a time proportioning output that is particularly useful for corrosion inhibitor dosing. A 10% to 100% linear proportional dose can be set using a graduated potentiometer.

The BC93 has a second relay, with a fully adjustable high or low control set point that can be used for a variety of dosing and bleeding applications. It can also be configured as an alarm device to operate a safety valve or klaxon. The BC94 has a second relay, configured as a dose alarm device, perhaps used to operate a safety valve or klaxon. The timer can be set from 1-60 minutes. If any single dose exceeds the set time, the dose relay and LED is de-energised, the alarm relay is energised and the alarm LED flashes. A low-tank switch input can also activate the alarm condition. The BC92,...
