Description: Captures temperature signals of refrigerant, chilled water, cooling water, compressor discharge gas and motor windings; converts readings into electric signals and transmits them to the PLC controller.
1. Control Functions: Regulates electronic expansion valve opening, unit start stop and capacity loading / unloading.
2. Protection Functions: High low temperature protection, discharge over temperature protection and anti freeze protection; prevents pipe freezing and overheating burnout of the main compressor.
3. Monitoring & Display: Real time panel readout for water and oil temperatures; logs operating data and triggers alarm warnings.
Immersive waterproof cylindrical metal probe: NTC thermistor chip encapsulated inside a stainless steel tube, filled with thermally conductive compound, tail compression sealed. Equipped with TPE waterproof cable for direct submersion measurement. Thread free design, mountable via pipe clamps; widely used for water tank and pipeline temperature measurement.
1. Probe housing: 304 stainless steel
2. Sensing element: NTC thermistor (ceramic semiconductor chip)
3. Cable sheath: TPE, flex resistant and waterproof
4. Internal filling: Thermally conductive epoxy resin for sealed encapsulation
