Overview
The Delavan 4-00-95 is an ultrasonic control device from the Sonac series, engineered for reliable liquid level detection and control. This used unit represents a cost-effective solution for industrial facilities requiring level monitoring and alarm functionality in bulk liquid storage, process tanks, and overflow prevention systems. The Delavan 4-00-95 is built on proven magnetostrictive ultrasonic technology, making it suitable for applications where process liquids vary in physical or electrical properties.
Key Features
- Ultrasonic magnetostrictive sensing for non-contact level detection
- Fail-safe operation modes for critical process control
- Vibration-resistant design for harsh industrial environments
- Independent time-delay adjustment for hysteresis control
- Compatible with standard industrial power supplies and auxiliary relay modules
- Used, tested condition—fully functional surplus unit
Technical Specifications
While the Delavan 4-00-95 operates within Delavan’s established ultrasonic control architecture, detailed voltage, I/O, and switching ratings should be confirmed with the original equipment documentation or contact information provided with your unit. Typical Sonac series units support dual operating modes (high/low switch setpoints) and standard industrial control voltages (12V, 24V DC or 115/230V AC via auxiliary power modules such as the Delavan 920-2F relay supply).
Typical Applications
- Liquid level point detection and alarm in storage tanks
- Overflow prevention in bulk liquid handling systems
- Process tank level control in petrochemical, chemical, food, and pharmaceutical industries
- Water treatment and waste management level sensing
- Industrial batch processes requiring precise level switching
