Product Highlights
The 901 Prescal…Ex® ATEX Adjustable Pressure switch offers versatile options for setting ranges, making it suitable for various applications. The switch is available in different types, each with specific setting ranges and maximum positive and negative working pressures. The Type 901.61 Ex, for example, has a setting range between 5 and 20 mbar with a maximum positive working pressure of 0.5/4 bar and no negative working pressure.
On the other hand, Type 901.66 Ex features a wider setting range between 250 and 1,000 mbar with a maximum positive working pressure of 10 bar and a negative working pressure of -1 bar. The switch also provides a broad temperature range from -20°C to 85°C, making it suitable for various environmental conditions. With options for different diaphragm materials, pressure connections, and electrical ratings, the 901 Prescal…Ex® ATEX Adjustable Pressure switch offers adaptability and reliability. Its IP 54 protection class ensures resistance to dust and water, making it suitable for challenging industrial environments.
Applications
The wastewater technology sector relies heavily on robust and reliable pressure switches like the 901 Prescal…Ex® ATEX to ensure safe and efficient operation of treatment plants. In these environments, the pressure switch is used to monitor and control the pressure within pipes and tanks, helping to prevent overpressure situations that could lead to leaks, equipment damage, or environmental contamination. Its ATEX certification makes it especially suitable for hazardous areas where explosive gases or dust may be present, providing an added layer of safety for both personnel and infrastructure.
In liquid level measurement applications, the 901 Prescal…Ex® ATEX pressure switch plays a crucial role in monitoring the height of liquids within tanks or reservoirs. By detecting changes in pressure that correspond to varying liquid levels, the switch can trigger alarms or control systems to maintain optimal levels, prevent overflow, and ensure continuous operation. This is particularly important in industries where precise liquid management is essential, such as chemical processing, food and beverage production, and water treatment facilities.
Pump control is another key application for the 901 Prescal…Ex® ATEX pressure switch. Pumps are often used to move fluids through pipelines or systems, and maintaining the correct pressure is vital for their efficient and safe operation. The pressure switch can automatically start or stop pumps based on preset pressure thresholds, protecting the system from damage due to excessive pressure or dry running. This automation not only enhances system reliability but also reduces the need for manual intervention, improving overall operational efficiency.
In the field of medical technology, the 901 Prescal…Ex® ATEX pressure switch is used in various medical devices and systems that require precise pressure monitoring and control. For example, it can be found in sterilization equipment, gas supply systems, and laboratory apparatus where maintaining specific pressure conditions is critical for safety and performance. The switch’s high accuracy and reliability make it suitable for sensitive medical environments, ensuring that equipment operates within safe parameters and complies with stringent regulatory standards.
