1. Raw Material Sourcing & Inspection: Begin with high-grade PEEK granules (specifically selected for thermal and chemical resistance), certified 316L Stainless Steel rods, and pure electrode materials (graphite, platinum, titanium). All incoming materials undergo rigorous quality checks to verify composition, purity, and adherence to ASTM standards for metallurgy and polymers.
2. Precision Machining (CNC & Injection Molding): The PEEK sensor body components are precision injection molded or CNC machined to tight tolerances, ensuring accurate electrode spacing and robust sealing surfaces. The 316L Stainless Steel fittings and housing elements are precisely CNC machined, guaranteeing perfect fitment and pressure integrity. This step is critical for maintaining the sensor's cell constant and pressure rating.
3. Electrode Preparation & Integration: Depending on the variant, graphite electrodes are carefully prepared, platinum electrodes are precisely formed, or titanium electrodes undergo Physical Vapor Deposition (PVD) for enhanced durability and specific conductivity ranges. These electrodes are then meticulously integrated into the PEEK body, ensuring electrical isolation and structural integrity, often involving specialized high-temperature bonding agents.
4. Sensor Assembly & Sealing: All components, including the integrated Pt1000 RTD for temperature compensation, are carefully assembled in a clean environment. Advanced sealing techniques, often involving high-temperature resistant O-rings and specialized epoxies, are employed to ensure a hermetic seal against process media and prevent ingress, contributing to the sensor's IP68 rating and impressive usage lifespan (typically 5-7 years in continuous operation).
5. Initial Electrical & Leak Testing: Each assembled sensor undergoes initial electrical continuity tests to verify electrode integrity and RTD functionality. A pressure leak test (hydrostatic or pneumatic) is performed to confirm the sensor's ability to withstand its rated pressure (up to 1.6 MPa) without leakage, ensuring safety and reliability in high-pressure applications.
6. Multi-Point Calibration & Validation: Sensors are calibrated against NIST-traceable conductivity standards across their full measurement range and operating temperature range. This multi-point calibration ensures accuracy and linearity, confirming the specified ±1% of full scale accuracy (temperature compensated). Validation protocols include extended high-temperature cycling tests to simulate real-world conditions and verify long-term stability.

The true measure of a sensor's effectiveness lies in its performance in real-world industrial environments. The CR-102H has been successfully deployed in numerous critical applications, demonstrating its superior capabilities and delivering tangible benefits to our clients.
A large thermal power plant faced persistent issues with scale formation in its high-pressure boilers, leading to reduced efficiency and increased downtime for descaling. Their existing conductivity sensors, rated for lower temperatures, frequently failed or drifted in the 150°C boiler blowdown lines, providing unreliable data. After implementing the CR-102H, the plant achieved continuous, accurate monitoring of boiler water conductivity at actual operating temperatures. This enabled them to precisely control blowdown rates, maintaining optimal water chemistry and preventing scale buildup. Over the first year, the plant reported a 7% increase in boiler efficiency and a 30% reduction in chemical treatment costs due to more accurate dosing, along with a significant decrease in unscheduled maintenance. The CR-102H's robust design and long-term stability were key to these improvements.
A manufacturer of specialty chemicals needed precise conductivity control for a hot, highly corrosive acid solution used in a key synthesis step, operating at 120°C. Their previous sensors, made from less resistant materials, corroded rapidly, requiring replacement every few months, leading to significant material costs and production interruptions. Our team recommended the CR-102H with its PEEK body and specialized electrodes. Since installation 2.5 years ago, the CR-102H has performed flawlessly, providing consistent and accurate readings. This has led to a 25% improvement in product yield consistency and an estimated $50,000 annual saving in sensor replacement and maintenance costs. The sensor's anti-corrosion capabilities and extended usage lifespan were critical factors in this success.
A textile dyeing and finishing mill was struggling with compliance for hot, chemically aggressive wastewater discharge. The temperature of the effluent often exceeded the limits of their standard sensors, leading to erroneous readings and potential non-compliance penalties. By integrating the CR-102H, they could accurately monitor the conductivity of the hot effluent up to 90°C, allowing them to optimize their neutralization and treatment processes in real-time. This proactive approach resulted in 100% compliance with discharge regulations over the past year and identified opportunities for water reuse, contributing to their sustainability goals and demonstrating significant energy savings by reducing the need for extensive post-treatment cooling.
