Description
KSR Kuebler BGU-AHT Magnetic Switch for Bypass Level Indicators
Genuine KSR Kuebler (WIKA Group) | High-Temperature Industrial Level Sensing
This item is a genuine, unused KSR Kuebler magnetic switch from surplus inventory. Because it is unsealed and missing its original factory retail box, we are listing it under “Used / Open Box” status. The unit is functionally pristine, physically clean, and fully operational. Please examine all listing photos carefully to verify physical appearance, housing details, and connection specs prior to purchase.
Product Overview
The KSR Kuebler BGU-AHT is an industrial-grade magnetic switch engineered specifically for mounting on bypass level indicators (magnetic level gauges).
Featuring a high-temperature construction (“AHT” execution) and a non-contact bistable switching contact, the BGU-AHT detects high or low liquid level limits via the magnetic field of an internal bypass float. This design guarantees complete electrical isolation from process fluids, providing reliable signaling for pump control, high/low alarms, and system interlocks in high-heat industrial processing plants.

Key Features
- Non-Contact Magnetic Operation: Actuates seamlessly through the bypass chamber tube wall without direct contact with process liquid or pressure vessel contents.
- Bistable Switching Memory: Holds its electrical state (ON/OFF) after the float magnet passes, preventing false signal resets during continuous level changes.
- High-Temperature Durability: Specialized AHT enclosure design withstands elevated thermal loads common in steam systems, thermal oil loops, and chemical processing lines.
- Easy Clamp Mounting: Mounts externally to standard bypass level indicator tubes using stainless steel hose clamps for quick height adjustments and zero downtime installation.
