DOL 26 Amnestic grain sensor CA-P-18-NF-CA-SCR-B-0T, 105137

What is the DOL 26 CA-P-18-NF-CA-SCR-B-0T capacitive sensor and what is it used for?

The DOL 26 CA-P-18-NF-CA-SCR-B-0T capacitive sensor is a maximally simple to use model of the DOL 26 series with factory calibration. The main feature of this version (index 0T) is the complete absence of adjustment screws. The sensor is configured by the manufacturer to a standard sensitivity for most types of grain and dry feed.

The model has a universal thyristor output (SCR) and NC (Normally Closed / Break) logic, which makes it an ideal solution for emergency stop functions or filling control without the risk of personnel messing up the settings.

Key advantages of the DOL 26 CA-P-18-NF-CA-SCR-B-0T capacitive sensor

• "Fit and Forget" principle (0T). Does not require sensitivity or time delay adjustment. This eliminates installation errors or unauthorized interference by operators in the system operation.
• Factory reliability. Operating parameters are fixed at the optimal level for grain and compound feed detection, guaranteeing stable operation in typical conditions.
• Universal power supply (SCR). Operates in the 20–280 V AC/DC range. Easily integrates into any existing farm power supply system.
• IP69K Protection. Fully sealed housing, resistant to pressure washing and aggressive ammonia environments.

Applications of the DOL 26 CA-P-18-NF-CA-SCR-B-0T capacitive sensor

Thanks to fixed settings, this model is best suited for standard tasks:

• Standard dry feed distribution lines. Where the raw material type does not change often.
• Overflow protection ("Stop" sensor). NC (Break) logic automatically opens the circuit when the hopper is full.
• Sites with low-skilled personnel. Where it is important to avoid the situation "someone twisted the sensor, and everything stopped working".
• Basic automation systems. An economical solution for simple level control tasks.

Why choose the DOL 26 CA-P-18-NF-CA-SCR-B-0T capacitive sensor

This is a choice in favor of stability and simplicity. If you have standard feed and want to avoid problems with incorrect equipment setup — the 0T model is the best option.

Mounting the DOL 26 CA-P-18-NF-CA-SCR-B-0T capacitive sensor

1. Mechanical installation: Install the sensor in the hole. Since it is impossible to adjust sensitivity, it is critically important to maintain the correct distance from walls and other metal parts to avoid false signals.
2. Connection: Connect the two wires in series with the load (relay coil). Polarity does not matter (for the AC/DC version).
3. Check: Just apply power. If the hopper is empty — the system should start. If the sensor is covered by hand or grain — the system should stop. No screwdrivers needed.

Comparison of model 0T (without settings) with model 2T (with settings)

What is the difference between the fixed and adjustable versions:

The 0T model is the standard of reliability for typical tasks where complex manipulations are not needed.
