The SAX Capacitance Level Switch is a reliable industrial level monitoring device designed to detect the presence or absence of materials inside tanks, silos, and storage vessels. Built for industrial automation environments, this switch provides dependable point-level detection for liquids, powders, granules, and bulk materials. Its rugged construction and flexible probe configurations make it suitable for diverse industries including chemical processing, food manufacturing, pharmaceuticals, and bulk material handling.
Capacitance sensing technology enables the device to detect material levels by measuring changes in electrical capacitance between the sensing probe and the surrounding vessel. When the material level reaches the probe, the capacitance changes and triggers the switching output, allowing process systems to activate alarms, pumps, or control systems.
Key Features
The SAX Capacitance Level Switch offers multiple advanced features designed for reliable process control:
- Capacitance sensing technology for accurate point-level detection
- Suitable for liquids, powders, granules, flakes, and pastes
- Adjustable sensitivity and time delay settings
- Ground level test function for easy maintenance
- High temperature resistance up to extreme process environments
- Durable industrial housing for long-term operation
- Available in explosion-proof and corrosion-resistant versions
These features ensure consistent performance even in challenging industrial conditions.
Design & Functionality
The design of the SAX series eliminates moving mechanical parts, reducing wear and minimizing maintenance requirements. The sensing probe acts as one electrode while the tank wall functions as the second electrode. When the material reaches the probe, the dielectric constant changes and alters the capacitance value, activating the switching circuit.
This simple yet effective design allows the switch to perform reliably even in environments with dust, vibration, or high temperatures.
Total Crossed Beams
The sensing mechanism operates by detecting electrical field changes around the probe when material contacts or surrounds the sensor. This ensures accurate level detection even when materials vary in density or conductivity.
Beam Pitch Options
Different probe configurations are available to suit various industrial installation needs. Options include standard probes, remote probes for vibrating environments, wire probes for tall silos, and plate probes for bulk materials. These variations allow the switch to be adapted to specific process requirements.
Intrinsic Synchronism
The switch maintains stable detection by using calibrated capacitance sensing circuits. This ensures consistent switching signals regardless of minor variations in material properties or environmental conditions.
Operational Advantages
The SAX Capacitance Level Switch provides multiple operational benefits for industrial processes. Its maintenance-free design reduces downtime and operating costs. Adjustable sensitivity allows operators to fine-tune detection accuracy for different materials. With multiple probe options and explosion-proof configurations available, the switch can be used safely in hazardous or demanding environments. These advantages make it an ideal solution for automated level monitoring in tanks, silos, and storage systems.
