Product Highlights
The Pressure switch 901 Prescal® EX is a versatile and reliable instrument designed to measure and control pressure in various applications. Available in different types with a wide setting range, the switch caters to diverse pressure requirements. Its standard/extended models offer setting ranges between 5 and 20 mbar up to 1,000 and 3,000 mbar, while the maximum positive working pressure ranges from 0.5/4 bar to 10 bar. The device also features a temperature range from -20°C to 85°C for media and ambient temperatures, ensuring effective operation in various environments.
The diaphragm material is customisable, with options like NBR, Silicone, FKM (Viton®), and EPDM depending on the media. The Pressure switch 901 Prescal® EX comes with multiple pressure connection choices, including PA, PVDF, PPS, Brass, and Stainless Steel materials, and various hose nipple and thread options. Its electrical rating is 24 VDC/100 mA or 30 VDC/45 mA, and it can be connected through AMP flat plug 6.3 x 0.8 mm or push-on screw terminals. With an IP 54 protection class (with cover 6371), this pressure switch guarantees durability and performance in demanding industrial settings.
Applications
The wastewater technology sector benefits greatly from the Pressure Switch 901 Prescal® EX due to its robust design and reliable performance in harsh environments. In wastewater treatment plants, maintaining optimal pressure levels is crucial for the safe and efficient operation of pumps, valves, and filtration systems. The switch’s ability to withstand aggressive media and its explosion-proof certification make it ideal for monitoring and controlling pressure in processes where safety and durability are paramount.
In liquid level measurement applications, the 901 Prescal® EX is used to detect and control the level of liquids in tanks and reservoirs. By monitoring the pressure exerted by the liquid column, the switch can trigger alarms or activate pumps to maintain desired levels, preventing overflows or dry running. Its precise switching capabilities and compatibility with a wide range of fluids make it a reliable choice for industries that require accurate level control, such as chemical processing and water management.
Pump control is another key application for the Pressure Switch 901 Prescal® EX. The switch can be integrated into pump systems to automatically start or stop pumps based on preset pressure thresholds. This not only helps in maintaining consistent system pressure but also protects pumps from damage due to conditions like cavitation or excessive pressure. Its robust construction ensures long-term reliability even in demanding industrial environments, reducing maintenance needs and operational downtime.
In the field of medical technology, the 901 Prescal® EX is valued for its precision and safety features. Medical devices and systems often require strict pressure monitoring to ensure patient safety and the proper functioning of equipment such as sterilizers, autoclaves, and gas supply systems. The switch’s high accuracy and compliance with safety standards make it suitable for use in sensitive medical applications, where reliability and hygiene are critical.
