Controller-level switch ERSU-K2 is designed to alarm and maintain in the prescribed limits of water level in steam boilers.
Controller-level switch ERSU-K2 is designed to alarm and maintain in the prescribed limits of water level in steam boilers and for control of other fluids, relevant technical the characteristics of the device.
Normal regulator operation is guaranteed when the air temperature from -10 to +45°C and relative humidity up to 98% at 35°C and without moisture condensation.
The number of signal positions of level - 4 (lower, upper, middle, emergency).
- Voltage mains frequency 50 or 60 Hz, 220±22.
- Power consumption, W, not more than 15.
- Bands, trigger conductivity control environment, Ohm/m
the first is the resistance of 5000 Ohms - 0,015
the second is the resistance of 700 Ohms - 0,006.
- Error trigger level, mm +10.
- Breaking capacity of the relay contacts when the voltage is 220 VAC, VA - 300.
- Working pressure in the object, kgf/cm2, not more than 25.
- Temperature controlled environment, °C, not more than 200.
- AC voltage on the electrodes of the sensors, not more than 7.
- The length of the probe immersed in the vessel, m is 0,1.
- The materials of the parts of the sensor - 12Kh18N10T steel, titanium, W-5, Teflon 4.
Weight, kg, not more than 4.
Overall dimensions, mm - HH.
- Service life, years 10.
The principle of operation of the level switch is based on the change electrical resistance between the electrode of the sensor and the vessel wall. Immersion of the electrode of the sensor in a controlled environment causes a decrease resistance, drying sensor - increasing resistance.
