Teknik Bilgi

Sensor Interchangeable digital relative humidity and temperature sensor Measuring range 0…100 %RH / recommended 5…80 %RH -20…+80 °C / -20…+80 °C Td Resolution 0.1 %RH / 0.1 °C / 0.1 °C Td Accuracy Typ. ± 2.5 %RH (5…80 %RH) @ t = 15…35 °C Typ. ± 0.3 °C @ t = -20…70 °C / ± 0.5 °C @ t = remaining range For the Dew Point see the table below Long term drift Typ. < 0.25 %RH/year Max. 0.03 °C/year Response time 10 s (63% of final value with 1 m/s air flow) Output • HVAC4017…: Active analog 0…20 or 4…20 mA (RLmax = 500 Ω) • HVAC40V17…: Analog 0…10 Vdc (RLmin = 10 kΩ) • HVAC40A17…: 2-wire (current loop) 4…20 mA (RLmax = (Vdc-12)/0,022) • HVAC40S17…: Digital RS485 Modbus-RTU • HVAC40R17…: ON/OFF relay switch with SPDT contact 3 A/250 Vac, 3 A/30 Vdc resistive load The analog output goes to 22 mA or 11 V in case of measurement outside the measuring range. Alarm Front red LED: exceeding of the set measurements thresholds in HVAC40R17… models, measurement detected outside the measuring range in the other models. Internal buzzer in HVAC40R17… models. Power supply • HVAC4017… and HVAC40V17…: 24 Vac ± 10% or 18…40 Vdc • HVAC40A17…: 15…30 Vdc • HVAC40S17…: 12…30 Vdc • HVAC40R17…: 24 Vac ± 10% or 15…36 Vdc Power consumption • HVAC4017…: 20 mA @ 24 Vdc and Iout=12 mA • HVAC40V17…: 4 mA @ 24 Vdc • HVAC40S17…: 2 mA @ 24 Vdc • HVAC40R17…: < 1 W @ 24 Vdc Electrical connections Screw terminal block, max 1.5 mm2 , PG9 cable gland Connection to PC RS232 serial port (except HVAC40S17…) RS485 serial port (only HVAC40S17…) Can be connected to a USB port by using the optional CP27 (except HVAC40S17…) or RS48 (only HVAC40S17…) adapter Sensor operating conditions -20…+80 °C. The sensor shows best performance when operated in 20…80 %RH humidity range. Long term exposure outside the indicated range (especially at high humidity) may temporarily offset the sensor response. The sensor is protected from water and dust. Instrument operating conditions -20…+60 °C / 0…95 %RH Storage temperature -20…+80 °C Housing dimensions 80 x 84 x 44 mm Protection degree IP65
