Humidity switches

• Capacitive moisture measurement
• Temperature range of measuring material: 4...50 °C
• Direct measured values transfer from the sensor
• Calibration is made directly at sensor, beyond the process

• Capacitive moisture measurement
• Up to 16 sensors per signal processing unit
• Temperature range of measuring material: 4...80 °C
• Measured value transfer: Profibus DP or analogue standard signal (e.g. 4...20 mA) optional
• Continuous measurement or batch operation

Humidity and temperature regulator AR247 is designed for temperature and humidity control. The device is made with either integrated or cable-connected sensor. Protection class is IP65. Optionally can be ordered: RS-232 or RS-485 ports, analog output 0/4...20 mA or 0...10 VDC (for control or signal transmission).

• Temperature measurement range:
  a) Ambient model: -20...+80 °C
  b) Remote model with polycarbonate probe: -20...+80 °C
  c) Remote model with stainless steel probe: -40...180 °C
• Relative humidity measurement range: 0...100 %
• Calculates dew point, absolute humidity, enthalpy and combination ratio
• 4-wire analog output: 0...5/10 V or 0/4...20 mA
• 2 relay outputs
• Versions with or without display
• Protection class: IP65 (ABS V0 housing)

HST comes in three models, HST-M – standard model (IP20), HST-D – remote sensor (IP65) and HST-A – channel model (IP65).

Temperature, humidity, pressure, CO2 regulators, 3 binary inputs, RS-485, RS-232 interfaces, Ethernet and 2 relay outputs.
