Abstract
Devices, methods and systems are provided for monitoring of industrial processes. Devices and systems are provided which include a controller module connected to a probe module having a specified metallurgy and a resistor module having a specified resistance value which is capable of identifying the metallurgy of the probe module to the controller module. A resistor device including a resistor having a resistance value which identifies a type of metallurgical material is also provided. The devices and systems provided are inexpensive, portable, easy to set-up and operate by unskilled personnel, may be connected to both desktop and portable computerized devices and can provide real-time monitoring of industrial processes.
Claims12
A corrosion monitoring device comprising:
- a controller module;
- a probe module which operably communicates with the controller module;
- a resistor module which operably communicates with the controller module;
- wherein the probe module includes at least two metallurgical probe electrodes;
- wherein the resistor module is capable of identifying the type of probe module to the controller module because said resistor module includes a resistance value which identifies the type of metallurgy of the probe electrodes to the controller module;
- wherein said corrosion monitoring device further includes a display device which operably communicates with the controller module;
- wherein said corrosion monitoring device can be operated without having to have the operator provide any further programming, pressing of buttons, operation of instructional menus, calibrations or auxiliary power source hook up.
A corrosion monitoring system comprising:
- a controller module;
- a probe module having at least two metallurgical probe electrodes which operably communicate with the controller module;
- a resistor module having a resistance value which operably communicates with the controller module, wherein the resistance value identifies to the controller module the type of metallurgy of the probe electrodes;
- wherein said corrosion monitoring system further includes a display device which operably communicates with the controller module;
- wherein said corrosion monitoring system can be operated without having to have the operator provide any further programming, pressing of buttons, operation of instructional menus, calibrations or auxiliary power source hook up.
A method of determining corrosion rate comprising the steps of:
- (a) providing a corrosion monitoring device;
- wherein said corrosion monitoring device comprises:
- (i) a controller module;
- (ii) a probe module having at least two metallurgical probe electrodes which operably communicate with the controller module;
- (iii) a resistor module having a resistance value which operably communicates with the controller module, wherein the resistance value identifies to the controller module the type of metallurgy of the probe electrodes;
- (b) placing the probe module within a solution;
- (c) charging the resistor module with a current via the controller module;
- (d) identifying the type of probe module by the controller module based upon the resistance value of the charged resistor module;
- and
- (iv) determining the rate of corrosion by the controller module after the probe module has been identified;
- wherein said corrosion monitoring device further includes a display device which operably communicates with the controller module.
