Siemens PLC Interface Module with 24 V DC Power Supply Category 5 Twisted Pair Transmission and Under 0.5ms Response Time

Product Overview and Core Specifications​

The +GF+ model 727798795 is a specialized Signet 2850 pH/ORP Combination Electrode, engineered for challenging applications where fouling, coating, or harsh chemical conditions are primary concerns. This robust sensor incorporates a pressurized, flowing liquid reference system, unlike standard gel-filled electrodes, to ensure superior performance and longevity. Key specifications include a highly chemical-resistant PEEK body and a unique PTFE annular junction that is exceptionally resistant to clogging. It is designed for continuous operation at temperatures up to 100°C and pressures up to 100 PSI. A critical parameter is its refillable 4M KCI liquid electrolyte reservoir, which helps maintain a stable reference potential and allows for easy maintenance. The electrode also features a built-in temperature sensor (NTC 30kΩ) for automatic temperature compensation, ensuring measurement accuracy across varying process conditions.

​Functional Application and Process Role​

The primary function of this electrode is to deliver stable and reliable pH or ORP measurements in demanding processes where standard electrodes would rapidly fail or provide unreliable readings. It is specifically designed for applications involving heavy fouling, such as wastewater containing fats, oils, and greases, paper pulp streams, coating slurries, or processes with high concentrations of proteins or sulfides. The pressurized, flowing reference junction actively prevents process media from clogging the junction, making it ideal for use in food & beverage, pharmaceutical, mining, and aggressive industrial wastewater treatment. It connects to compatible transmitters like the Signet 2952, providing a precise millivolt signal that is converted for automated control of chemical feed pumps, neutralization processes, or oxidation/reduction reactions, ensuring consistent product quality and regulatory compliance.

​Distinctive Advantages and Operational Benefits​

The key advantage of the +GF+ 727798795 is its exceptional resilience and long-term stability in problematic media, which directly translates to reduced maintenance frequency and lower total cost of ownership. The pressurized liquid reference system provides a stable signal and actively cleans the junction, minimizing drift and the need for constant cleaning. The refillable electrolyte reservoir is a significant benefit, allowing for easy servicing on-site without replacing the entire electrode, which cuts spare parts inventory costs. For operators, this means dramatically extended service intervals, fewer false alarms, more consistent process control, and less exposure to hazardous chemicals during maintenance. This results in increased process uptime, improved safety, and significant savings in operational and maintenance resources.
