Finned Tubular Heater Surge Current Capture & High-Speed Data Acquisition

Finned tubular heater cold start surge current is short duration transient; standard multi-meter cannot capture the 1~3 second peak. Finned tubular heater high-speed DAQ system samples current, voltage and temperature at millisecond interval to record cold inrush waveform. Finned tubular heater DAQ capture objective: verify peak current magnitude, decay time and correlation with sheath temperature rise. Finned tubular heater waveform data validates soft start performance and detects abnormal insulation leakage transients. Chuanli Cold Storage Electric Defrosting Tubes uses high-speed DAQ for prototype validation and batch audit testing. Finned tubular heater measurement wiring requirement: current transducer placed close to heater branch to exclude cable induced noise. Finned tubular heater common measurement error: noise pickup from fan and compressor wiring distorting transient waveform. Finned tubular heater data post-processing: filter high frequency noise and extract peak value, integral energy and rise time. Finned tubular heater acceptance criteria: measured cold surge current not exceeding 1.25 × rated branch current. Finned tubular heater high-speed DAQ provides objective waveform evidence for cold start transient and controller performance verification.
