Alvi Technologies introduces the Unical 9000 electro-pneumatic controllers.
Designed for fully automated pH measurement, cleaning, and calibration, the Unical provides the ideal functionality of a complete system for automatic control of a pH measurement.
Combined with the Protos process analysis system and a SensoGate or Ceramat sensor lock-gate, the Unical 9000 electro-pneumatic controllers allow highly accurate measurements to be taken even under difficult process conditions such as high pressure, high temperatures, and high levels of impurities. The systems can be installed next to the process, within the hazardous area.
Measurements in pressure tanks or main pipes can continue uninterrupted thanks to the fact that the electrode is not dismounted for calibration.
Other benefits of the the Unical 9000 electro-pneumatic controllers include:
Cost-efficiency: Low-wear and low-maintenance pump with extremely low consumption of buffer.
Long sensor life also in critical processes: When measuring in aggressive media or at high process temperatures, the electrode rests in the calibration chamber and is only briefly moved into the process for measurement. This method decisively increases the sensor life.
Safe and easy measurement even in strongly polluted media: Sensor cleaning and rinsing is performed in user-defined intervals. Cleaning solution and water are automatically pumped into the calibration chamber. Dismounting and manual cleaning of the sensor are omitted.
Modern fieldbus integration: The interfaces to PROFIBUS PA or Foundation Fieldbus allow the Unical system to be integrated directly in a fieldbus network.
Universal adaptation to retractable fittings: The modular structure of the Unical 9000 electro-pneumatic controllers allows any retractable fitting to be used. Optimum functionality is achieved with the Ceramat and SensoGate sensor lock-gates.
Clear and safe construction: All features for a smooth, safe, and low-maintenance operation are provided as standard: water pressure gauge and service switch with alert message and check-back signal for the actual lock-gate position, air filter and water trap, flooding sensor in the housing with alert message.
