Flush diaphragm electronic pressure switches are specifically designed for applications where the process media needs to be in direct contact with the sensing element. This type of pressure switch is characterized by its open diaphragm design, which allows the process media to directly interface with the diaphragm without any intervening components. This design is particularly beneficial for applications where hygiene and cleanliness are paramount, such as in the food and beverage, pharmaceutical, and biotechnology industries.
Working Principle
These switches utilize a piezoresistive sensing element that measures the pressure exerted by the process media on the diaphragm. As the pressure changes, the resistance of the piezoresistive element changes proportionally. This change in resistance is then converted into an electrical signal, which is typically a transistor switch output. The switch output can be used to control various devices, such as pumps, valves, or alarms.
Applications
The versatility of flush diaphragm electronic pressure switches makes them suitable for a wide range of applications. Their ability to accurately measure pressure in hygienic environments makes them particularly well-suited for industries such as food and beverage, pharmaceutical, and biotechnology.
- Liquid Level Control: Flush diaphragm pressure switches are commonly used to monitor and control liquid levels in tanks, vessels, and pipelines. For instance, they can be used to activate a pump when the liquid level falls below a certain threshold or to shut off a valve when the tank is full.
- Process Monitoring: These switches can also be used to monitor process pressures and trigger alarms or control actions when the pressure deviates from the set point. This is particularly useful in applications where pressure fluctuations can affect product quality or process safety.
- Hygienic Applications: The open diaphragm design makes these switches suitable for hygienic applications where cleanliness is critical. The absence of dead spaces or crevices prevents the buildup of bacteria or other contaminants, ensuring product purity and process integrity.
