BAPI BA/H200 HUMIDITY TRANSMITTER | ±2% ACCURACY HVAC RH SENSOR

The BAPI BA/H200 series comprises high-accuracy humidity transmitters engineered specifically for demanding HVAC environments, offering precision monitoring for duct, room, and outdoor applications.

A highly reliable humidity transmitter providing ±2% accuracy with field-selectable outputs for commercial building automation.

 

BAPI BA/H200 HUMIDITY TRANSMITTER | ±2% ACCURACY HVAC RH SENSOR

The BA/H200 series features a capacitive polymer sensing element that is factory-calibrated at multiple points (typically 10 to 17 points) to ensure high linearity and minimal hysteresis. Designed to withstand real-world conditions, the units are available in various rugged enclosures, including the BAPI-Box (IP66/NEMA 4) and Weatherproof (NEMA 3R) versions. These transmitters often include replaceable sensor tips and can be paired with optional passive temperature sensors (thermistor or RTD).

PRODUCT USES:

  • Commercial HVAC: Accurate monitoring of supply, return, and discharge air.
  • Critical Environments: Humidity control in clean rooms, data centers, and hospitals.
  • Energy Management: Economizer control and psychrometric calculations (Dew Point/Enthalpy).
  • Specialized Facilities: Environmental regulation in schools and office buildings.
