The Pyxis CR300 Series corrosion rate sensors are ideal for cooling and process water treatment monitoring where robustness and affordability are a must. The sensors utilize the linear polarization resistance (LPR) method to produce a raw signal. The raw signal is conditioned, amplified, and digitized directly in the sensor itself. This avoids the interferences and attenuation of the raw signal caused by long-distance wiring needed for other corrosion probes to a separate signal conditioner or transmitter box. The Pyxis corrosion sensors measure sample water conductivity directly and compensate for the conductivity impact on the LPR measurement up to 10,000 μS/cm. These unique product characteristics make the Pyxis LPR superior in performance and accuracy. In addition to the LPR measurement to obtain the general corrosion rate, the CR-Series sensors also measure electrochemical noise. The measured noise data is used to calculate an index to quantify the localized corrosion rate also referred to as pitting.
The CR-300 is a standalone sensor that can be powered by a 24 VDC power source such as an existing controller, PLC or DCS network. The output data signals for both general and localized corrosion are offered in both 4- 20mA and RS-485 modbus using the provided 8Pin cables with quick adapters. The CR-300 will come with one MA-CR Pyxis Bluetooth Adapter allowing the unit to be wirelessly configured and viewed via the uPyxis APP for Mobile or Desktop devices.
