Capacitive Feed Level Relay Sensor DOL 44RR-33 (90–265V AC)
The DOL 44RR-33 is a high-precision intelligent level sensor designed for direct supply from 90–265V AC alternating current power networks. This model serves as an industry benchmark in automated feeding systems, ensuring reliable detection of grain, compound feed, and other bulk materials even in dusty or humid conditions. The built-in switching power supply makes the device highly resistant to voltage fluctuations often encountered in rural areas.

The device is equipped with a high-capacity changeover relay (NO and NC), allowing the installer to select the desired system logic ("Start" or "Stop") directly during setup. The "33" variant offers superior stability against intense airflows, and its two trimmers enable independent adjustment of sensitivity and time delay, protecting motors from frequent restarts.
The DOL 44RR-33 excels in mounting durability, featuring a reinforced M30 threaded housing. It can be securely fixed in 30.5 mm holes using the included plastic nuts, preventing displacement from mechanical vibration. With an IP69K protection rating and fully encapsulated electronics, the sensor is completely resistant to humidity, ammonia fumes, and high-pressure hot water cleaning.
