DF341 Capacitance Level Sensor
Customizable level sensing for water, gasoline, diesel, and industrial containers
DF341 is the upgraded replacement for DF340. It uses a capacitance probe with flexible aluminum alloy length, high-resolution measurement, wired and wireless output options, BLE configuration, and firmware upgrade support for project deployment and maintenance.
Customer Value
Why choose DF341 for liquid level projects
Wired and wireless outputs
Support 0-5V, 4-20 mA, RS232, RS485, 4G LTE, and LoRaWAN options so project teams can match existing controllers, gateways, or cloud platforms.
High resolution
Resolution reaches 1 mm or 0.5% FS, supporting short-range and container-level monitoring where stable measurement detail matters.
Flexible probe length
The aluminum alloy probe can be trimmed to adapt to different tank and container heights, reducing model complexity for project deployment.
BLE configuration and FOTA
BLE setup supports parameter configuration and maintenance access. FOTA support helps firmware upgrades without replacing field devices.
PC and mobile app support
Support Windows, Android, and iOS operation workflows for configuration, maintenance, and project commissioning.
Industrial-grade deployment
IP68 protection, flange mounting, easy installation, and 12-24 VDC power options support field and industrial monitoring scenarios.
Applications
Suitable for common liquid level monitoring projects
DF341 is designed for capacitance level measurement in water, gasoline, diesel, and similar project media. It is suitable for tanks, containers, equipment reservoirs, and industrial liquid-level monitoring where a cuttable probe and multiple output options are useful.
Application note: DF341 is not recommended for ethanol or methanol. For special media, installation structure, or certification requirements, confirm compatibility with CNDINGTEK before project rollout.
Water
Utility tanks, service containers, and equipment reservoirs.
Gasoline
Fuel-related monitoring projects after site compatibility confirmation.
Diesel
Industrial fuel containers and distributed tank monitoring.
More media
Project-specific media can be evaluated before bulk deployment.
Installation and Structure
Flange mounting with adjustable probe length
DF341 supports flange mounting for straightforward installation. The probe can be cut according to tank height, helping customers standardize one model across multiple container sizes.
