Compact Dew Point Transmitter (CI-TM02)
-
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;
-
Compact size, easy to install in small spaces.
