Keunggulan Teknis Kritis
-
Robust Ceramic Technology: The sensor is crafted from 99.9% high-purity Al2O3 ceramic (Ceraphire). This “dry” measuring cell is oil-free, eliminating the risk of process contamination, and is highly resistant to abrasion and chemical attack.
-
Density-Compensated Accuracy: Using HART 6.0, the device can perform density-corrected level measurements. This ensures the highest level of accuracy (up to ±0.1% in the “Platinum” version) even when the liquid density changes due to temperature fluctuations.
-
Climate-Proof Electronics: The electronics are completely potted to prevent moisture ingress, and the device features a unique 2-filter pressure compensation system. This makes the sensor virtually immune to the internal condensation that often plagues submersible instruments.
-
Dual Measurement Capability: The FMX21 can optionally include an integrated Pt100 sensor. This allows the device to provide a 4-20mA signal for level while simultaneously outputting highly accurate temperature data via the HART protocol.
-
Specialized Application Versions: The transmitter is available in three distinct configurations tailored for specific environments:
-
Drinking Water: Certified with international approvals for clean water supply.
-
Wastewater & Sewage: Designed to handle sludges and contaminated liquids.
-
Saltwater: Built with materials resistant to the corrosive effects of seawater and brine.
-
-
Slimline Design: With a 22mm (0.87″) outer diameter, the drinking water version is ideally suited for monitoring deep wells and small-diameter boreholes.
