CR-300 Inline Corrosion Sensor - 4-20mA / RS485 Modbus by Quantrol

The use of the LPR corrosion rate represents a valuable tool that can be easily and affordably deployed to provide both general and localized corrosion measurements in an instantaneous format. There is a common industrial misnomer that the use of inline LPR corrosion sensors should be identical to that of corrosion coupons. The LPR corrosion level represents the real-time electrochemical measurement of corrosion. While it may be linear with respect to the corrosion rate obtained from the weight loss of a coupon exposed to water for a long period, the LPR corrosion rate may not necessarily be the same exact value of the latter. The instantaneous nature of the device measurement represents a "real-time condition" on an MPY scale based on the specific metallurgy being assessed and will in many cases vary, in a short time scale, from a corrosion coupon. The LPR data should be used to best understand the linear relationship with coupons and for real-time application performance assessment and adjustment.

The Pyxis CR-200/300 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. 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-200/300 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 or PLC.

The CR-200 is a battery powered and Bluetooth® enabled corrosion sensor for true wireless connectivity. A centralized Bluetooth® enabled display panel available via the BTA-100 for single probe or the BTA-400 for multiple probes can be used to display the readings from an array of CR-200 sensors. The CR-200 makes it possible to monitor corrosion at multiple test points, avoiding the complications of running power and signal output wires from the sensor to a controller and/or display unit. The CR-200 sensor can store up to 6-months' worth of data that can be wirelessly downloaded to a computer or phone using the uPyxis APP.

The CR-300, with the addition of a Pyxis Bluetooth Adpter (MA-WB), and the CR-200 can both communicate with any smart device via the uPyxis app. The uPyxis app, available for all smart phones and computers, is used to configure and obtain current sensor readings. Additional diagnostic information is available and can be used for determining the sensor performance or the need for maintenance.

The CR-200/300 sensors accept various test metal electrodes commonly used in the industry (LowCarbon Steel, Copper, Admiralty Brass, 304 Stainless Steel, Copper Nickel, Aluminum 1100 &6061).

Key Features

• High resistance to color and turbidity interference from sample water
• Digital communication via Bluetooth to smart phone app for diagnosis and troubleshooting
• Highly stable and extremely reliable even in harsh applications

Accurate Traced Chemical Monitoring:

The ST 500 inline fluorometer, state of the art technology was developed by Pyxis Lab, Inc. in the United States. It measures traced chemical residue every 4 seconds in the sample water with 2% accuracy. It allows an optimal narrow band control in the treatment chemical concentration for cost effectiveness and, more importantly, best treatment performance.

High Rejection to Turbidity and Color Interference:

Turbidity and color in most cooling tower applications interfere traditional fluorimeters and lead to significant dosing errors, even up to 50%. With the ST 500's proprietary optical design and sophisticated compensation algorithm, the ST 500 delivers great precision and accuracy for waters containing up to 150 NTU turbidity and 4 ppm iron. This breakthrough technology ensures ST 500 to outperform in the toughest cooling water applications while keeping maintenance demand at a minimum with our uPyxis diagnostics capabilities.
