AMETEK PROCESS INSTRUMENTS PRODUCT DATA SHEET 5812 Moisture Analyzer Reliable moisture in natural gas measurement KEY BENEFITS • Reliable performance • Internal verification on process gas • Fast response APPLICATIONS • Moisture in natural gas Measuring moisture in natural gas is not a difficult application, but reliably measuring on a continuous basis is. The 5812 Moisture Analyzer is designed specifically to meet the needs of the natural gas industry for reliable, low maintenance, and self-verifying moisture analysis. The 5812 measures moisture by monitoring the performance of a solid-state, water sensitized quartz-crystal. As wet sample gas passes over the crystal, moisture is sorbed onto the crystal's coated surface. The crystal is then exposed to dried sample gas and moisture is released. The difference in the wet and dry performance of the crystal is proportional to sample moisture level. This continuous cycling between wet sample and dry sample gases results in the analyzer being constantly ready to detect and respond to changes in moisture. It is the combination of quartz-crystal sensing and asymmetrical sampling which provides the rugged, reliable, continuous performance demanded in natural gas moisture analysis. Long sensor life The 5812 has an exceptional sensor life due to its unique asymmetrical sensing technology, which limits the exposure of the sensing element to potentially dirty natural gas. During asymmetrical sensing, the 5812 directs natural gas into the sensor module for 30 seconds, then directs clean, dry gas for the next 9.5 minutes. In each 10-minute measurement period, the sensor module is exposed to dirty natural gas for only 5% of the time. For the remainder of the measurement period, clean gas protects the sensor and strips away volatile contaminants. Wide performance range The 5812 is calibrated from 1 to 1000 parts per million by volume (ppmv) and provides trend indication above the calibrated range. Alternative output in pounds per million cubic feet is standard. True process analyzer features Data is provided by RS485 digital interface and two fully programmable 4-20 mA analog outputs. Multiple programmable alarms allow the user to monitor both process conditions and analyzer performance. The RS485 is particularly useful for remote monitoring or troubleshooting an unattended 5812.
