2. Product Introduction
Engineered specifically for high-accuracy pressure and vapor monitoring in demanding industrial and marine tank gauging systems, the Druck PDCR250-2967 delivers precise piezoresistive pressure measurement performance.
Integrated directly into industrial process vessels or marine cargo monitoring setups (such as Saab TankRadar inventory systems), the hardware measures low-range gauge pressures while maintaining intrinsic safety compliance in explosive atmospheres. (Instrumentation engineers rely on this dependable Druck sensor tier to ensure stable, drift-free level and vapor pressure tracking under harsh environmental conditions.)

4. Global Compliance & Industry Certifications
Auditors and marine safety classification societies enforcing hazardous area safety protocols demand rigorous documentation standards for low-range pressure transmitters.
- Expected Certifications: ATEX / IECEx Intrinsic Safety (EEx ia IIC T4), CE Mark, and compliance with marine classification guidelines for tank monitoring.
- Safety Relevance: Strict intrinsic safety electrical parameters (U_i, I_i, P_i) prevent electrical arcs or thermal ignition when deployed inside volatile vapor zones or classified hazardous fuel storage spaces.
- Audit Directive: Verify specific hazardous area certificates. Ensure the serial barcode and intrinsic safety entity parameters match the vessel or plant’s certified loop diagrams and safety barriers.
5. Long-Term Storage & Asset Preservation Guide
Precision low-range pressure transducers kept in warehouse reserve stock degrade prematurely if environmental baselines are neglected.
- ESD & Transient Protection: Keep the sensor sealed inside its original metallized anti-static shielding bag to protect internal micro-electronics from electrostatic discharge.
- Diaphragm Protection: Never touch or press directly on the exposed pressure sensing diaphragm. Always keep the protective plastic cap threaded or seated over the process port during storage to prevent mechanical rupture.
- Climate Management: Maintain warehouse storage relative humidity strictly below 60% non-condensing, avoiding wide thermal oscillations.
6. Physical Installation Prerequisites
Proper mechanical handling and strict adherence to intrinsic safety loop rules are mandatory during transmitter deployment.
- Diaphragm Integrity Check: Inspect the process connection and sensing diaphragm carefully for particulate debris or physical denting prior to thread engagement.
- Barrier Compatibility: Always connect the sensor through an approved galvanic isolator or zener barrier matching the EEx ia IIC T4 entity ratings. Direct unconditioned power application will void intrinsic safety compliance.
- Thread Sealing: Use approved thread sealant compatible with the process media to prevent vapor leaks without over-tightening the process connection fitting.
7. Buyer’s FAQ (Logistics & Compliance Focus)
Q: What Harmonized System (HS) Tariff Code applies to global shipments of this pressure sensor?
A: Industrial pressure transducers, transmitters, and measuring instruments typically clear under HS Code 9026.20 (Instruments and apparatus for measuring or checking pressure). Confirm exact sub-headings with your customs broker.
Q: Does importing this marine-grade pressure transmitter require an authentic Certificate of Origin (COO)?
A: Yes. Securing a formal Certificate of Origin from your vendor verifies manufacturing traceability, which is vital for quality assurance compliance and customs clearance.
Q: Is the PDCR250-2967 a direct substitute for standard 4-20mA pressure transmitters?
A: No. The PDCR250-2967 requires a specialized excitation voltage supply (typically 5.6 to 7.0 VDC) and is designed specifically for integration loops (such as Saab TankRadar systems) rather than standard loop-powered 4-20mA inputs. Always verify loop compatibility.
