Wind speed, temperature, humidity transmitter / HD29□□T
In HVAC/BEMS, the control of air velocity involves air velocity, temperature, and humidity transmitters.
HD2903T･HD29V3T: Wind Speed HD2937T･HD29V37T: Wind Speed・Temperature HD29371T･HD29V371T: Wind Speed・Temperature・Humidity ■ Used for wind speed control in HVAC/BEMS applications ■ Ensures accurate and reliable continuous measurements through selected sensor elements and electronics ■ Capable of use in harsh applications with thin-film sensors for wind speed, AISI304 probe sheath, and 20μ metal filter for relative humidity ■ Analog output options of 4–20mA and 0–10V, with wind speed measurement range and response speed (Fast/Slow) selectable by the user ■ Available in two types: "TO type" with the probe joined at a right angle to the back of the main case, and "TC type" connected to the main case via a cable ▲ Analog output DC4–20mA or DC0–10V ▲ Switchable wind speed range and response time (FAST/SLOW) ▲ Back-mounted/separated probe ▲ AISI304 sheath, IP67
basic information
■ Wind speed measurement range (selectable via dip switch) Measurement range 1: 0.05–1.00 m/s Measurement range 2: 0.1–2.0 m/s Measurement range 3: 0.2–10.0 m/s Measurement range 4: 0.2–20.0 m/s ■ Wind speed measurement accuracy (at 50% RH, 1013 hPa) Measurement range 1: ±(0.1 m/s + 3% of the measured value) Measurement range 2: ±(0.15 m/s + 3% of the measured value) Measurement range 3: ±(0.5 m/s + 3% of the measured value) Measurement range 4: ±(0.7 m/s + 3% of the measured value) ■ Output (varies by model): 4–20 mA (RL < 500 Ω) DC 0–10 V (RL > 10 kΩ) [For HD2937T, HD29V37T, HD29371T, HD29V371T] ■ Temperature measurement range: -10 to +60℃ ■ Temperature measurement accuracy: ±0.3℃ [For HD29371T, HD29V371T] ■ Relative humidity measurement range: 0–100% RH ■ Relative humidity measurement accuracy: Temperature range 15–35℃: ±1.5% RH (in the range of 10–90% RH), ±2.0% RH (outside the above range) Outside the above temperature range: ±(1.5 + 1.5% rdg) % RH ■ Relative humidity output range: 0–100% RH
