CHT-DS Series Duct Temperature and Humidity Transmitter
The CHT-DS series duct temperature and humidity transmitter utilizes imported digital temperature and humidity sensors, pre-calibrated during production with calibration data stored internally. Featuring digital output for both relative humidity and temperature, these transmitters offer excellent interchangeability without complex calibration. They excel in measurement accuracy, linearity, repeatability, interchangeability, and consistency, making them suitable for environmental equipment, instrument integration, and general environmental testing.

Data Conversion Methods
Temperature Conversion (for -30~70):
0-2V DC: T = 50*V - 30
0-5V DC: T = 20*V - 30
0-10V DC: T = 10*V - 30
4-20mA: T = 6.25*A - 55
Humidity Conversion:
0-2V DC: H = 50*V
0-5V DC: H = 20*V
0-10V DC: H = 10*V
4-20mA: H = 6.25*A - 25
RS485: Standard Modbus-RTU protocol, Baud rate: 4800; Parity: None; Data bits: 8; Stop bits: 1.
Important Notes
- Inspect packaging upon receipt and verify product model and specifications.
- Install away from corrosive environments.
- Keep sensors and wiring away from high voltage and heat sources.
- Store sensors in a dry, ventilated, and normal temperature indoor environment.
- Do not disassemble the sensor to avoid damage.
