●Learning control
A function for automatically calculating and setting the offset value (correction value for the set temperature).
A temperature sensor (external sensor) is provided near the object to be tempe♏rature controlled, and those signals are input to the chiller. The offset value is automatically calculated from the deviation between the discharged temperature and the external s💟ensor.
●Level switch
A switch that detects the fluid level inside the liquid tank. There are many different types, but the most common type employs a floating buoy, which causes a lead switch (magnetic switch) to turn ON and OFF.●Lifting height/Pressure
Lifting height (in meters) is often used instead of pressure to indicate the pump capacity. Lifting height is a numerical value that indicates the capacity of a pump in terms of the height (in meters) to which it can lift a fluid.
The value for pressure is obtained by multiplying the lifting height by the density of the fluid; for example, if a pump capable of generating a lifting height of 10 meters is used to pump water, which has a density of 1 kg/L, the unit pressure generated by the pump is 1 kgf/cm2 (0.1 MPa).
If a more dense fluid is used, the pressure is higher even though the lif♏ting height remains the same.
