All versions use a hall sensor to measure the oil level. A magnetic float changes its position according to the oil level. The hall sensor converts these magnetic field changes into an equivalent signal, which is used by the internal electronics to show the actual oil level with LEDs and activate the integrated solenoid valve to feed missing oil directly into the compressor sump. For application in refrigeration systems according to EN 378.
Notes:
• TR4 is developed for all traditional refrigerants and subcritical CO2.
• TR5 is specially adapted to the requirements of transcritical CO2 systems and must be used with dedicated types of CO2 adapters.
• An A-7 or Y11236-C valve is not required with a TraxOil oil level control.
