The Endress+Hauser CPY7B is an electrolyte vessel designed to provide a top-up supply of liquid electrolyte to unpressurized or pressurized electrodes and to create an electrolyte bridge in measuring devices with reference electrodes. This device is crucial for maintaining the functionality and accuracy of various analytical measurement systems, particularly those involving pH/redox measurements.
The primary function of the CPY7B electrolyte vessel is to ensure a continuous and stable supply of electrolyte to electrodes. This is vital for the proper operation of electrochemical sensors, as the electrolyte facilitates ion transport and maintains the reference potential. For pressurized systems, the CPY7B-B and CPY7B-C versions are specifically designed to handle internal pressure, ensuring that the electrolyte can be supplied even when the electrode is operating in a pressurized process. The vessel can be wall-mounted or installed on an assembly head, offering flexibility in integration into existing systems. It features a manually operated valve for controlling the electrolyte flow and, in pressurized versions, connections for compressed air or an air pump to maintain the necessary pressure. The design allows for easy refilling of electrolyte and includes provisions for venting the system to prevent airlocks.
The CPY7B is designed for straightforward use and integration. It supports both unpressurized (CPY7B-A) and pressurized (CPY7B-B, CPY7B-C) applications, making it versatile for different process requirements. The device comes with a comprehensive scope of delivery, including a spacer tube, PTFE pressure hose, an open-ended wrench, and specific components depending on the version (e.g., fixing bracket, threaded joint, hose couplings with check valve, air pump connection, spiral pressure hose, hose connector).
Installation can be done via wall mounting using a fixing bracket or directly on an assembly head like the CPA111. Clear instructions are provided for both methods, emphasizing the importance of secure and leak-tight connections. For pressurized systems, it is critical to ensure the system is unpressurized and vented before installation or removal, and to never exceed the maximum permitted pressure of 11 bar (160 psi) at 30 °C (86 °F). The use of only the supplied pressure hose is recommended, and regular checks for leaks and damage are advised. In processes with fluctuating medium pressure, the electrolyte vessel's pressure should always be maintained above the medium pressure.
Filling the vessel with electrolyte involves a series of steps, including closing the manually operated valve, undoing the hose union, removing the upper section by loosening the coupling nut with the provided wrench, and then carefully pouring in the electrolyte without overfilling. For unpressurized versions, some of these steps are not required, simplifying the process. After filling, venting the electrolyte hose is necessary to prevent air bubbles from affecting measurements. This is achieved by releasing the hose connection on the sensor and pressing the tappet of the hose union until electrolyte flows, then reconnecting.
Routine checks are essential for the CPY7B to ensure its reliable operation. All couplings should be regularly checked for leaks. For pressurized versions (CPY7B-B, CPY7B-C), this involves cutting off the compressed air supply, observing the pressure gauge for 15 minutes to confirm leak-tightness, and re-tightening couplings or checking seals if a pressure drop occurs.
Releasing vessel pressure is a critical maintenance step for pressurized versions before any other work is performed. If an air pump connection is used, the valve nipple on the cover should be released by one rotation. For compressed air connections, the supply must be cut off, the compressed air hose removed, and then pressure released from the vessel by toggling the manually operated valve.
A crucial safety warning regarding prohibited lubricants is highlighted: only lubricants approved for polycarbonate parts should be used to prevent stress cracks. Users are advised to observe the lubricant manufacturer's instructions.
Spare parts are readily available, including pressure hoses, spiral hoses, fixing brackets, mounting kits for compressed air or air pump connections, hose unions with check valves, O-ring maintenance kits, coupling nuts, and various cover kits (CPY7B-Ax, CPY7B-Bx, CPY7-Cx) which may include pre-assembled hand valves. The pressure vessel itself is also available as a spare part.
In case of repairs, factory calibration, or incorrect product delivery, a clear return procedure is outlined, directing users to the Endress+Hauser support website for detailed instructions on returning materials, emphasizing safe and professional handling of products that have been in contact with process media. Disposal of the device should always adhere to local regulations.
