Design & Working Principle

Integrated Sensing Technology

T & RH sensors combine temperature sensing elements with relative humidity sensors in a single integrated package. Temperature measurement typically uses RTD (Resistance Temperature Detector) or thermistor elements, while humidity sensing utilizes capacitive polymer technology. The sensor measures temperature through electrical resistance changes and humidity through capacitance changes in the polymer film. These measurements are processed by onboard electronics to provide accurate, calibrated outputs for control systems.

Selection Guidelines

Choosing the Right T & RH Sensor

Selecting the appropriate temperature and humidity sensor requires consideration of measurement range, accuracy requirements, environmental conditions, output signals, and installation requirements. For HVAC applications, consider sensors with appropriate accuracy and response time. For industrial processes, evaluate chemical compatibility and explosion-proof requirements. Critical applications like pharmaceutical clean rooms require high accuracy and calibration certificates. Always consider long-term stability, maintenance requirements, and integration with existing control systems when selecting T & RH sensors.
