DOL 26 capacitive grain sensor CA-P-18-NF-CA-SCR-B-2T,105121

What is the DOL 26 CA-P-18-NF-CA-SCR-B-2T capacitive sensor and what is it used for?

The DOL 26 CA-P-18-NF-CA-SCR-B-2T capacitive sensor is a professional model in a smooth housing (Ø18 mm) that combines the hygiene of threadless mounting with full adjustment functionality. Unlike simplified versions, this model is equipped with two trimmers, allowing it to be adapted to non-standard feed or complex operating conditions.

The electrical part is based on a thyristor (SCR), which allows connecting the sensor to any voltage in the range of 20–280 V AC/DC. The logic is Break (NC / Normally Closed): the contact opens when full, stopping the line.

Key advantages of the DOL 26 CA-P-18-NF-CA-SCR-B-2T capacitive sensor

• Smooth housing + Settings. A rare combination that allows using the sensor in sanitary zones (easy to clean, no thread) and yet finely adjust sensitivity and delay.
• "Slip-fit" mounting. Ideal for systems where the trigger level needs to be changed frequently. Simply loosen the clamp and slide the sensor up or down the pipe.
• Power universality (SCR). Does not require 24V power supplies. Works directly from the contactor control network (220V).
• Reliable "Stop". NC logic guarantees system stop even in case of cable break, preventing accidents.

Applications of the DOL 26 CA-P-18-NF-CA-SCR-B-2T capacitive sensor

This model is best suited for:

• Control feeders with variable volume. Where mechanical adjustment of the feed column height is required.
• Working with complex mixtures. Thanks to the trimmers, you can adjust the sensor to detect light husks or, conversely, ignore them.
• Retrofitting old lines. Replacing old mechanical switches with a modern electronic sensor without rewiring (2 wires).
• Sterile zones. The absence of threads prevents dirt from accumulating on the housing.

Why choose the DOL 26 CA-P-18-NF-CA-SCR-B-2T capacitive sensor

This is the choice of professionals who know that "standard" settings do not always fit. This model gives you freedom: freedom of voltage choice, freedom of mounting (smooth housing), and freedom of parameter setting.

Mounting and setting up the DOL 26 CA-P-18-NF-CA-SCR-B-2T capacitive sensor

1. Installation: Use a cable gland or rubber seal. Do not try to cut threads. Insert the sensor to the required depth.
2. "Sens" Calibration: If the sensor does not see light feed — turn the sensitivity trimmer clockwise. If it reacts to dust — counter-clockwise.
3. "Time" Calibration: Set the off delay to compensate for feed fluctuations during auger operation.
