SA - Capacitive Level Sensor 136629B

General Description:

The SA series sensor is a versatile, wear-resistant switch designed for detecting the level of liquids and bulk materials. It operates on the principle of electrical capacitance measurement – ​​detecting changes in the dielectric and conductivity of the medium, enabling precise determination of the material's presence without the need for moving parts. This makes the sensor wear-free and suitable for applications requiring reliability and hygiene.
Available in many variants (standard, high-temperature, anti-corrosion, explosion-proof, etc.) – making it an ideal solution for use in demanding industrial environments.

Main Features:

• No moving parts – high durability, no mechanical wear
• Capacitive technology – precise detection of materials with different dielectric composition and conductivity
• Maximum operating temperature: up to 800°C
• Adjustable sensitivity and response delay
• Ground level test function
• Special versions:
• Standard Type (SA110 / SA111)
