AUTROL ALT 6600 SMART CAPACITANCE LEVEL TRANSMITTER | HART 4-20mA

The Autrol ALT 6600 utilizes advanced capacitance technology to provide precise level measurement by sensing changes in the dielectric constant between the probe and the tank wall. Designed for versatility, it features a 2-wire loop-powered 4-20mA output with integrated HART digital communication for seamless integration with DCS, PLC, and SCADA systems. Its robust construction includes options like PVC coating for corrosion resistance and is capable of handling high-viscosity, sticky, or corrosive media in pressurized tanks up to 20 bar. The transmitter includes on-site calibration via two external buttons (Zero and Span) and a continuous self-diagnosis function to ensure long-term stability and minimal maintenance.

PRODUCT USES:

  • Sticky & High-Viscosity Liquids: Reliable measurement for challenging media that tends to coat sensors.
  • Corrosive Environments: Ideal for chemical tanks requiring PVC or other protective coatings.
  • Solid Media: Suitable for measuring the level of powders or granules in industrial silos.
  • Pressurized Tanks: Designed for applications up to 20 bar (approx. 290 PSI).
  • Industrial Automation: Used across Water/Wastewater, Oil & Gas, and Chemical processing industries for closed-loop control
