In combination with process analytical system and a Senso-gate or cermat sensor lock -gate fittings, Unical provides the ideal functionality of a complete system for a automatic process control of pH measurement. It allows presice and accurate measurement in highly diverse condition. The system can be installed next to the process, within the hazardous area. Calibration is possible without disrupting the process,even when measuring directly in the pressure vessel. When measuring in aggressive media or at high process temperatures, the sensor rests in the calibration chamber and is only briefly moved into the process for measurement. This method increases the sensor life significantly. Sensor cleaning and rinsing is performed at user-defined intervals. Cleaning solution and water are automatically pumped into the calibration chamber. Removal and manual cleaning of the sensor are not required. The interfaces to PROFIBUS PA or Foundation Fieldbus allow the Unical system to be integrated directly in a fieldbus network. Of course, also in hazardous areas. All features for smooth, safe, and low-maintenance operation are included as standard: water pressure gage and service switch with alert message and feedback of the actual lock-gate position, air filter and water trap. Flooding sensor in the housing with alert message.
