•  Robust protection in washdown environments
•  Continuous liquid level measurement
•  Two wire loop powered (4-20 mA)

KING-GAGE® ES2 transmitters provide liquid level measurement for inventory monitoring. Add to their rugged reliability the major benefits of simplified service and maintenance. Performance characteristics of these transmitters include excellent stability and repeatability (better than 0.02% FS). Transmitter span accommodates a 3:1 turndown ratio* to match the application pressure range (i.e. tank depth) and the 4-20 mAdc output is compatible with PLCs or other control architecture using analog I/O.

KING-GAGE ES2 transmitters are applicable to most tanks or process vessels whose contents remain at normal atmospheric pressure. They measure hydrostatic head pressure created by liquid depth in the tank and are unaffected by foaming or internal obstructions such as agitators. Unlike load cells, pressure based measurement has lower installation cost and is far simpler to maintain thus ensuring more reliable readings.

Transmitters used in sanitary processing must often endure cycles of rapid temperature fluctuation. Washdown environments produce significant condensation on metallic surfaces that coupled with aggressive cleansing agents demand robust protection for these instruments. The ES2 transmitter's enhanced design uses encapsulation for full isolation of the internal electronics. This extends to the IP68 grade M12 signal connector that ensure integrity and long term reliability. You can be assured of a transmitter truly built for the demands and expectations of today's processing environment.

Sanitary Configurations
These sensors are especially suited to a wide range of sanitary applications on storage or continuous processing vessels. The 316 stainless diaphragm is appropriate for flush mount, clean-in-place installation employing an FDA-approved silicone rubber O-ring seal to achieve the crevice-free, positive compression seal between diaphragm and tank liner. Sanitary tank mountings include flush weld mountings with product contact surfaces of 316L stainless. (Quick disconnect sanitary adapters are also available for sensor mounting.)

*3:1 turndown ratio is applicable to 0-10 and 0-30 nominal range, refer to specifications for detailed span adjustment available on specific range models.

• Simple Inline Installation
• Float Check Avoids Pressure Drop
• Guards Against Siphoning From Tank

This engineered component will help you prevent siphoning or backflow of liquid through a downpipe installed in tank level gauging applications. With the KING-GAGE® Downpipe Backflow Check Valve, you can guard against liquid traveling up through the downpipe and into the system pressure lines. It utilizes a specially designed float pin that rises up to seal the valve shut when liquid enters from the downpipe through the bottom of the unit. The Model 6563 Downpipe Check Valve is well suited for use on downpipe systems employing KING-GAGE Purge Control or LiquiSeal Purge Control liquid level transmitters.

• Flush Mount Sanitary Design
• Field Replaceable Sensor Diaphragm
• Hybrid Design Minimizes Temperature Effects

KING-GAGE® AcraSensor unit detects level by sensing pressure due to liquid depth while its pneumatic force balance diaphragm technique is remarkably free from drift or temperature effects. These sensors are especially suited to a wide range of sanitary applications on storage or continuous processing vessels. The standard AcraSensor + 868 D/P Sensor Control combination combines accuracy, rugged durability, reduced maintenance, and long term stability for liquid level tank gauging. Its integral transmitter converts the pneumatic isolation pressure to a proportional 4-20 mAdc signal suitable for process control or remote level indication.

The unique AcraSensor titanium diaphragm satisfies the 3-A Sanitary Standard (74-03) and is appropriate for flush mount, clean-in-place installation. An FDA-approved silicone rubber O-ring seal forms a crevice-free, positive compression seal between the diaphragm probe and mounting shell. Flush weld mountings are available with product contact surfaces of 316L stainless.

Operation requires pneumatic 860 Sensor Control or 868 D/P Sensor Control electronic transmitter and compressed air/gas supply.
