Three-channel level controller RU3
64€
The three-channel RU3 level control-signaling device is used for systems with automatic filling or draining of the tank according to the hysteresis law with an additional third input (can be used as an alarm level). The device has four modes of operation and can work with such types of sensors: conductometric, dry contact and open collector.
Three-channel level regulator-signaling device (RU3) are designed to automate technological processes related to monitoring and regulating the level of liquid and bulk substances, creating systems for automatically maintaining the level of liquid in tanks, storage tanks, etc. RU3 can work with liquids of different electrical conductivity: distilled, tap, polluted water, milk and food products (weakly acidic, alkaline, etc.).
Sensor types
- conductometric sensors;
- Dry contact;
- open collector.
Main functions of RU3
- automatic filling of the reservoir with hysteresis up to the set level;
- automatic drainage of the tank to a predetermined level;
- control of an external actuator (pump);
- light indication of the state of the output device;
- changing the parameters of the device (sensitivity). \
The level control-signaling device is manufactured in a housing for mounting on a DIN-rail and in two power modifications: from an alternating voltage network with a nominal value of 110 ... 240V or from a constant voltage source with a nominal value of 12..24V.
