Upgrading high-pressure measurement instruments for the hydrogenation unit
Challenge
The hydrogenation unit operates under high temperature and pressure with hydrogen-containing media. The existing instruments suffer from significant drift and require frequent maintenance, impacting the unit's long-term continuous operation.
Solution
Following WIKA's oil and gas solution, the UPT-20 process pressure transmitter paired with TR10 resistance thermometer features a metal sensing element resistant to hydrogen embrittlement. Combined with HART remote diagnostics, it enables real-time monitoring at critical measurement points.
