MaintenanceD A N G E RMultiple hazards. Only qualified personnel should conduct the tasks described in this section of the manual.ControllerRefer to the Maintenance section of the controller documentation.Clean the sensorW A R N I N GChemical hazard. Always wear personal safety protection in accordance with the Material Safety Data Sheet forthe chemical that is used.W A R N I N GPersonal injury hazard. Removal of a sensor from a pressurized vessel can be dangerous. Reduce the processpressure to below 10 psi before removal. If this is not possible, use extreme caution. Refer to the documentationsupplied with the mounting hardware for more information.Pre-requisite: Prepare a mild soap solution with a non-abrasive dishwashing detergent that does notcontain lanolin. Lanolin leaves a film on the electrode surface that can degrade the sensorperformance.Examine the sensor periodically for debris and deposits. Clean the sensor when there is a buildup ofdeposits or when performance has degraded.1. Use a clean, soft cloth to remove loose debris from the end of the sensor. Rinse the sensor withclean, warm water.2. Soak the sensor for 2 to 3 minutes in a soap solution.3. Use a soft bristle brush to scrub the entire measuring end of the sensor.4. If debris remains, soak the measuring end of the sensor in a dilute acid solution such as < 5%HCl for a maximum of 5 minutes.5. Rinse the sensor with water and then return to the soap solution for 2 to 3 minutes.6. Rinse the sensor with clean water.Always calibrate the sensor after maintenance procedures.Replacement parts and accessoriesNote: Product and Article numbers may vary for some selling regions.
