The FANTINI B12CN 0.2-8 Bar Pressure Switch is a high-quality device designed for the precise control and regulation of non-explosive fluids and gases. Ideal for applications such as compressor systems, boilers, tanks, autoclaves, ventilation, and lubrication systems, this pressure switch ensures optimal performance and safety across various industrial settings. **Key Features:** - **Pressure Range:** Adjustable from -0.2 to 8 bar, accommodating a wide spectrum of pressure requirements. - **Differential Pressure:** Configurable between 0.6 and 3 bar, allowing for tailored operational settings. - **Maximum Pressure:** The sensitive element withstands pressures up to 9 bar, ensuring durability under high-pressure conditions. - **Electrical Specifications:** Equipped with a changeover switch featuring AgCdO contacts, the device supports a rated insulation voltage of 415V~, with a continuous duty current of 16A. It handles resistive loads up to 16A at 380/415V~, inductive loads up to 6A at 380/415V~, and continuous DC loads up to 0.2A at 220V. - **Connection Type:** Features a G 1/4 female thread connection, facilitating easy integration into existing systems. - **Protection Class:** With an IP40 rating, the pressure switch offers reliable protection against dust and solid objects, making it suitable for various industrial environments. **Construction and Materials:** The B12CN pressure switch boasts a stainless steel, laser-welded diaphragm sensing element, ensuring high sensitivity and longevity. Its metal frame provides robust structural support, while the shockproof thermoplastic cover offers additional durability. The device includes a PVC cable gland for secure electrical connections, enhancing overall safety and performance. **Operational Temperature Range:** Designed to operate effectively in diverse conditions, the B12CN can handle controlled fluid temperatures up to 120°C. The pressure switch body remains functional within a temperature range of -35°C to 60°C, and it can withstand storage and transport temperatures between -35°C and 60°C. **Installation and Usage:** Installation is straightforward, with direct branch installation being the recommended method. The G 1/4 connection ensures compatibility with standard piping systems. For applications involving fluids with temperatures exceeding the maximum allowed, it's advisable to connect the pressure switch to the pipeline using a spiral-wound metal tube to facilitate heat dispersion. The device can also be mounted on a metal bracket, except for versions with a watertight housing. **Functionality:** In operation, as pressure increases, the switch opens contact 1-2 and closes contact 1-4. In models equipped with manual lockout and re-insertion at maximum pressure, re-insertion may occur when the pressure is below the value set on the differential, enhancing operational flexibility. The FANTINI B12CN 0.2-8 Bar Pressure Switch is engineered to deliver precise and reliable pressure control, making it an essential component for maintaining optimal performance and safety in various industrial applications.
