Capacitive Sensors

Smart capacitive BC/UC sensors from TURCK with IO-Link make capacitive detection more transparent, easier to configure, and more versatile. TAS significantly enhances the devices’ performance in everyday use: The TAS Teach Monitor displays process values, supports the teach-in process, and facilitates optimal adaptation to the medium, container wall, and installation situation. This makes commissioning, diagnostics, and readjustment faster and more reliable. Users benefit from stable presence, limit level, or fill level monitoring and better utilization of the devices’ functions.

For which applications is this product family particularly well-suited?

• Level and limit control with TAS-based parameterization and IO-Link
• Presence detection of liquids, powders, granules, and solid materials
• Machinery and packaging systems that frequently change media, formulations, or installation configurations

Cylindrical capacitive sensors from TURCK are designed for classic standard applications in machines and systems. Threaded-tube models are easy to install and reliably detect liquids, powders, granules, and solid materials—even through non-metallic container walls. Depending on the model, digital or analog signals and various housing sizes are available. Users benefit from robust, wear-free detection, easy integration, and stable presence, limit level, or fill level monitoring. The range extends from compact custom designs to K34/K40 devices with larger active areas and greater switching distances.

For which applications is this product family particularly well-suited?

• Low-level and level control for tanks, hoppers, and feeders
• Presence detection of plastic parts, liquids, powders, or granules
• Standardized sensors in packaging machines, dosing systems, and machine modules

Compact, rectangular QF-5.5 capacitive sensors from TURCK round out the product portfolio with exceptionally low-profile devices designed for tight installation spaces and level detection. The large active surface area ensures reliable detection of media or objects, such as in containers or inside machines. Depending on the model, a NAMUR output, ATEX approval for Ex zone 0/20, and SIL/PL ratings are available. Users benefit from wear-free detection, flexible mounting, and reliable solutions for standard, Ex, and safety applications. TURCK’s rectangular capacitive sensors for special applications handle demanding detection tasks where standard designs reach their mechanical or process-related limits.

For which applications is this product family particularly well-suited?

• Level measurement in tanks, e.g., for bulk materials or ground media
• Confined installation spaces with a flat mounting surface in machines and equipment
• Ex and safety-related applications with NAMUR signals, ATEX approval, and SIL/PL requirements

TURCK's portfolio of capacitive sensors for specialized applications in the hygiene and food & beverage sectors offers variants for food applications or media prone to adhesion. Rugged housings, suitable connection options, and compensation functions support reliable level detection, presence detection, and material identification in pharmaceutical, food, and process applications.

For which applications is this product family particularly well-suited? 

• Low-level and presence detection for active surfaces in contact with the process medium or under special installation conditions
• Applications involving media that adhere, change, or are difficult to detect
• Food, process, and special-purpose machinery applications with rugged, hygienic sensors
