Overview
AKUSENSE pipe level switches adopt capacitive non-contact sensing technology, mounted on the outer wall of non-metallic pipes without drilling or contacting the liquid. They provide stable and accurate liquid presence / level detection for pipeline applications, with IP65 enclosure rating, built-in multiple protection circuits and button-type sensitivity adjustment. Suitable for water treatment, chemical delivery, food & beverage and industrial automation pipeline systems. Bulk order inquiry and matching technical guidance are supported.
Key Features
- Non-contact Capacitive Sensing — clamp-on installation, no pipe drilling, no contact with media
- Dual Pipe Size Compatibility — fits Ø8~Ø11mm and Ø12~Ø26mm non-metallic pipes
- High Repeat Accuracy — ≤±0.2mm switching repeatability for reliable detection
- IP65 Enclosure Rating — dust-proof and water splash resistant for industrial environments
- Triple Circuit Protection — reverse polarity, overload and short-circuit protection
- Red LED Status Indicator — clear output status display for easy on-site debugging
- Button Sensitivity Adjustment — flexible setting for different liquid types and pipe walls
- 10~30V DC Wide Voltage — compatible with most industrial control systems
