Kriwan’s New Oil Level Regulator INT280-xxx Diagnose
2017/09/22
With the new INT280-xxx Diagnose, Kriwan is introducing a product for the heating, ventilation, air conditioning, and refrigeration (HVAC&R) market that makes Industry 4.0 more practical and concrete. In addition to its basic function, measuring the oil level and adding oil, this regulator especially captures valuable data that it uses for its own operation but is also able to communicate to various other devices.
 
In the age of Industry 4.0, Kriwan optical measurement has as a key benefit, an active transmitter diode and a passive receiver diode. The transmitter diode sends an infrared beam through a glass prism. Depending on the oil level, the receiver diode receives a stronger or weaker signal. The new INT280 Series uses the fact that the transmitter diode is an active component, can send a stronger or weaker control signal, which enables it to measure additional data with this modulation, enabling contamination in the refrigeration circuit to be detected.
