Capacitive Feed Level Relay Sensor DOL 44RRH-33 (90–265V AC)
The DOL 44RRH-33 is a premium intelligent capacitive relay sensor designed for direct connection to 90–265V AC alternating current networks. This model is the industry benchmark for reliability in livestock farming, ensuring high-precision detection of grain, compound feed, and bulk materials. Its integrated switching power supply guarantees stable operation even during significant voltage fluctuations often encountered in rural areas.
The device features a high-capacity 10A internal changeover relay (NO and NC), giving the installer the flexibility to select the desired control logic on-site. A key feature of the RRH modification is the integrated heating element, which maintains the sensor's internal temperature to prevent moisture condensation on the sensitive face. This eliminates false triggers and ensures 100% detection accuracy even in extreme humidity or cold environments.
Installation of the DOL 44RRH-33 is highly reliable thanks to its reinforced M30 threaded housing. The sensor is typically mounted in a 30.5 mm diameter hole and secured with the heavy-duty plastic nuts included, ensuring a rigid fit that prevents displacement from auger vibration. With an IP69K protection rating and fully encapsulated electronics, it is completely resistant to high-pressure hot water cleaning and harsh ammonia fumes.
