DatasheetThe Druck PDCR1800 and PTX1800 are high-performance, fully submersible pressure sensors designed for accurate measurement of liquid levels and water depths. Their robust titanium construction and high measurement accuracy make them particularly suitable for demanding applications in water management, industrial level monitoring and marine instrumentation.
These sensors measure the hydrostatic pressure of a liquid column, enabling reliable level and depth measurement. With measuring ranges from 0.75 to 600 mH₂O, they cover a wide variety of applications.
Differences Between PDCR1800 and PTX1800
The two model variants primarily differ in their electrical output signals:
- PDCR1800: Pressure transducer with an mV output signal for connection to suitable measurement and signal processing equipment.
- PTX1800: Pressure transmitter with a standardized 4–20 mA output signal for integration into industrial measurement and automation systems.
