❓ Frequently Asked Questions (FAQ)
Q1: What makes the Deltabar PMD50 more stable over long-term operations compared to baseline transmitters?
A: The Deltabar PMD50 features advanced metal membrane sensor technology that boasts exceptional resistance to long-term drift. It exhibits a minimal drift of just 0.25% of URL over a full 10-year operating cycle, drastically reducing the frequency and costs associated with routine field recalibration.
Q2: Can the PMD50 handle high-temperature and highly vacuumed process lines?
A: Yes. While the standard sensor cell operates up to +110°C (+230°F), configuring the Deltabar PMD50 with specialized high-quality diaphragm seals extends its safe thermal limits up to +400°C (+752°F). Additionally, it possesses a rugged vacuum resistance down to 25 mbar (0.0375 psi) abs.
Q3: How does the integrated RFID tag improve field asset management?
A: Unlike traditional paper labels or stamped metal tags that corrode in harsh environments, the PMD50 features a built-in digital RFID tag. Onsite technicians can instantly scan the device with a handheld reader to access factory calibration data, serial numbers, and maintenance logs, paving the way for digital plant tracking.
