Refrigerated Air Conditioning Industry

The instruments in refrigerated air conditioning industry are widely used where temperature, pressure, liquid level and flow rate need to be measured and controlled. For example, the liquid level instrument can be used to detect the refrigerant position in the evaporator or condenser of the central air conditioning unit, and it can also detect the height of the refrigerant in the liquid storage of the bucket pump unit. Products for detecting include magnetostrictive level transmitter, capacitance continuous level sensor, and magnetic float level transmitter etc. After systematic processing, these position data are used to accurately control the opening of expansion valve to make the unit more stable and energy efficient.

The small float switch and optical level switch can detect the oil level of the compressor oil and identify whether the oil return of the compressor is normal, thus protecting the normal operation of the compressor.
