NCON Conductivity Node
The Conductivity Node (NCON) is a LONWORKS* Technology-compatible node that uses twisted pair communications. The NCON works with several different temperature compensation inputs and with two-or four-electrode sensors. These multiple-sensor input options allow for various conductivity sensors to be used. Temperature compensation is adjustable by percent per degrees Celsius for use with various processes. The NCONs ability to cover a wide range in conductivity is due to its advanced auto-ranging circuitry. The NCONs four-electrode circuitry allows for compensation when fouling occurs on sensor electrodes. When sensor fouling can no longer be corrected, the NCON sends a fouled electrode alarm.
The NCON can be used with Osmonics« Lakewood 2000 Series Controllers. On cooling towers, it can be used for chill loop monitoring and control, as well as on the makeup line for multi-setpoint or cycles of concentration control. Up to eight NCONs may be used with the 2255 Multi Boiler Controller to control up to eight boilers.
One Network Interface Node (NIN) per 2000 Series Controller is required to operate network nodes such as the NCON.
