Fantini Cosmi Single Mercury Contact for Boiler Feeding: The Sensitive Key to Level Control Systems

Fantini Cosmi boiler feed devices are critical systems that precisely control water levels in steam boilers. The single mercury contact is a precision spare part used within these mechanical level switches, which acts as an on-off switch for the electrical circuit.

What is a Single Mercury Contact and What Does It Do?

A single mercury contact switch is a switch element consisting of a small amount of mercury and two electrical contacts inside a sealed glass tube . A mechanical level switch (or float switch) changes the angle of this glass tube by moving the float arm in response to the water level.

Single Mercury Contact Working Principle:

• Switching: When the glass tube is tilted, the mercury inside moves toward one end of the tube under the influence of gravity. During this movement, the mercury either brings two contacts together, closing the circuit, or separates them, opening the circuit.

• Precise Control: Mercury's surface tension allows contacts to bond quickly and reliably. This makes mercury contacts ideal for level switches requiring low power and precise switching.

• Safety and Isolation: Mercury is completely isolated in a closed glass tube.

Features and Advantages of Single Mercury Contact:

• Sealing: The hermetic (airtight) structure inside the glass tube prevents the internal mechanism from being affected by environmental factors (moisture, steam, dirt).

• High Reliability: Mercury contacts wear less and have a longer life than mechanical switches.

• Low Power Consumption: It requires very little energy for switching operation.

• Vibration Resistance: Thanks to the structure of mercury, it is not affected by slight vibrations in the mechanical system.

• Compact Spare Part: Used to replace faulty contacts in Fantini Cosmi boiler feed devices (level switches).

Single Mercury Contact Usage Areas:

• Steam Boilers: Repair of feedwater devices that control the boiler feedwater level.

• Hot Water Tanks: Level control systems.

• Industrial Machinery: Precision level or tilt sensors.

• Fantini Cosmi Tagdiye Devices: As an original spare part, it is used to maintain the correct operation and safety of the device.
