Oxygen Sensors, Hamilton VisiPro DO Ex Optical for Explosive Environments
Overview
The VisiPro DO is the only optical dissolved oxygen (DO) sensor for use in an explosive environment. With their integrated transmitter, VisiPro DO sensors enable direct communication to the process
control system via 2 wire 4-20 mA standard signal or digital HART. Wireless communication directly from the sensor may be used for monitoring, configuration and calibration, and can save time without compromising the quality of the wired connection.
Optical technology improves the measuring performance and simplifies maintenance. Improvements compared to conventional electrochemical (amperometric) sensors include flow independence, rapid start-up with no polarization time, and simplified maintenance. With their integrated transmitter, VisiPro DO sensors enable direct communication to the process control system via 2 wire 4-20 mA standard signal or digital HART.
All relevant sensor data including calibration and diagnostic information are stored in the sensor head, simplifying calibration and maintenance. Additional wireless communication directly from the sensor to a computer simplifies laboratory calibration, configuration, and maintenance.
Features of the VisiPro DO EX sensors:
ATEX EC type Examination Certificate for use in explosive atmosphere
Suitable for steam sterilization, and CIP
Flow independent self diagnostics
Electrolyte-free, so no leakages occur
No polarization time required
Easily replaceable sensor cap containing the sensing element
