DOL 26 Amnesiac sensor CA-P-M18-NF-CR-SCR-B-2T, 105204

What is the DOL 26 CA-P-M18-NF-CR-SCR-B-2T capacitive feed sensor and what is it used for?

The DOL 26 CA-P-M18-NF-CR-SCR-B-2T capacitive sensor is the benchmark of durability in the DOL 26 series. This model combines a chemically resistant housing (CR) and reliable threaded mounting (M18). It is designed specifically for stationary installation in the most aggressive zones of livestock complexes, where ordinary plastic deteriorates quickly, and clamp mounting is not reliable enough.

Electrically, it is a universal device (SCR AC/DC) with Break (NC) logic, designed for emergency line stops or overflow control. Thanks to the presence of two trimmers (2T), it can be precisely adapted to any operating conditions.

Key advantages of the DOL 26 CA-P-M18-NF-CR-SCR-B-2T capacitive sensor

• Chemical Protection (CR). The special polymer of the housing is inert to acids, alkalis, and aggressive detergents. This is critically important for piggeries and poultry houses with strict sanitary standards.
• Rigid Fixation (M18). The presence of threads allows the sensor to be tightly secured with two nuts. This eliminates the risk of the sensor slipping or shifting under the influence of auger vibration or high-pressure washing.
• Setting Flexibility (2T). The ability to adjust sensitivity and delay time allows this sensor to be used for specific feeds and additives.
• Connection Versatility (SCR). Works in any 20–280 V network without additional power supplies.

Applications of the DOL 26 CA-P-M18-NF-CR-SCR-B-2T capacitive sensor

This model is indispensable where vibration and aggressive chemistry combine:

• Pig farms with liquid feeding systems. Where contact with an acidic environment is possible, and pipe vibration requires threaded mounting.
• Intensive washing zones. Where a water jet can displace a sensor in a smooth housing but cannot move a threaded M18.
• Medication and additive dispensers. The chemically resistant housing does not react with active substances.
• Outdoor hoppers. CR material better withstands UV radiation and temperature changes.

Why choose the DOL 26 CA-P-M18-NF-CR-SCR-B-2T capacitive sensor

If you are tired of changing sensors because the plastic has become brittle from disinfection, or because the mounting has become loose — this "armored" threaded version will solve both problems.

Mounting and setting up the DOL 26 CA-P-M18-NF-CR-SCR-B-2T capacitive sensor

1. Mechanical fixation: Insert the sensor into an 18.5 mm hole. Tighten two plastic nuts on both sides of the wall. Ensure the active part (NF) protrudes inside and is not shielded by metal.
2. Connection: 2-wire SCR scheme. In series with the load.
3. Settings (2T): Open the cover. Adjust "Delay" to filter vibrations and "Sens" to precisely detect your feed type.
