The regulator ROS-301,GREW 301,Roast level

The sensor-relay level control relay level switch, controller water level Controller is used to control the water level in tanks, water towers, tanks, vessels and for vklucheniya and turn off the pump or pump unit, control valves, actuators valves, valves, etc. In addition voditku can sensor - regulator ROS-301 (sensor-relay) to control up to three levels all conductive liquids.
The principle of operation of the level switch ROS-301 based on the principle changes in resistance between electrodes immersed and not immersed in the conductive liquid.
Controller level switch ROS-301 is similar to the previously produced level controls ERSU-2, ERSU-3, ERSU-4, SU-300, SAU-M, ESP-50.
Parameters power supply (rated value):
AC voltage: 220, 380
frequency, Hz: 50

Power consumption, not more,·A: 7

The AC voltage on the electrodes of the sensors, not more, In: 6

The load on the output relay:
the current from 0.5 to 2.5 And frequency 50, 60 Hz, allowed to increase the current up to 5A at the time of not more than 0.1 S;
the voltage from 12 to 250 C.

The upper value of the resistance of the actuation resistance of the liquid between the electrode and the housing
sensor, when the output relay is triggered): 5000 Ohms

Ambient temperature, °C:
for a sensor from -50 to 70

for the transmitting transducer from 1 to 35

Relative humidity 80% at 25°C (without condensation) for transmitting
inverter and 100% at 25°C (condensing) sensor.

According to the degree of protection of the device from dust and water meets IP54 according to GOST 14254

In addition to sensor - level switch ROS-301, alarm relay level ROS-301 to offer devices new sample ERSU-3-1 and ERSU-4-1 which funkily replace ROS-301
