Product Description

The Fantini Cosmi AD23A is an electromechanical level detector for tank and vessel monitoring across industrial applications. It operates at pressures to 6 bar with a level differential range of 20-180 mm and handles liquids to 150°C. The IP54-rated unit with G 3/8 connection integrates into process control systems requiring reliable float-switch functionality.

Frequently Asked Questions

What is the Fantini Cosmi AD23A level detector used for?

The Fantini Cosmi AD23A is an electromechanical level detector for monitoring and controlling liquid levels in small pressurised tanks such as sterilizers, autoclaves, steam machines, and drink vending machines. It operates at pressures up to 6 bar and handles liquids up to 150 °C.

What are the specifications of the Fantini Cosmi AD23A?

The AD23A has a level differential range of 20–180 mm, maximum operating pressure of 6 bar, maximum liquid temperature of 150 °C, specific gravity range of 0.7–1.1 kg/dm³, IP54 protection, and a G 3/8 connection. It features a steel body with Teflon coating and an SPDT microswitch rated at 15 A continuous.

Where to buy the Fantini Cosmi AD23A in Singapore?

3G Electric supplies the Fantini Cosmi AD23A electromechanical level detector to Singapore. We handle logistics, customs clearance, and delivery to your facility. Contact our team for a quotation and lead time on this item.

How to install the Fantini Cosmi AD23A level detector?

Install the AD23A using a flange connection per UNI 2223 – DIN32 – PN6. Fasten it to the reservoir via a welded flange. Ensure the liquid specific gravity is between 0.7 and 1.1 kg/dm³. Wire the SPDT microswitch for emptying or filling pump control as shown in the Fantini Cosmi datasheet.
