Standard Dew Point Transmitter (CI-BM02)
Based on polymer thin film capacitive sensor technology;
Application in dewpoint > -60 °Ctd: Refrigerant dryers, desiccant dryers, industrial gases; 10+ points of dew point calibration and multi-point temperature compensation provide accurate measurements up to ±2 °Ctd;
Ultra-fast response time and outstanding long-term stability;
Anti-condensation, resistant to particulate contamination, oil vapor and most chemicals;
Excellent immunity to interference;
IP65 protection class, providing good protection even in harsh environments;
Provides comprehensive sensor setup, data transfer, software upgrades, and maintenance via Modbus RTU (RS485) interface and powerful service APP;
Calibration is valid for two years, reducing maintenance.
