Wet bulb temperature sensor (Tnw)

Naturally ventilated wet bulb temperature sensor

Thermometer probe with wet bulb and natural ventilation. ISO7726 standard. The Pt100 element is closed inside a wet cotton sock from a water tank. The water tank has a high reflection factor to avoid water temperature increase due to radiant sources. This sensor is needed for WBGT (ISO77243) heat stress index assessment.

Wet bulb temperature sensor (Tnw)

Highlights

  • Wet bulb temperature measurement with natural ventilation as required for the calculation of the WBGT index (ISO 7243) in fixed and/or outdoor installation;
  • Designed as described in the ISO 7726 standard for the “wet bulb temperature”;
  • 1/2 litre or 1 litre water tank for more than 30 days or 2 months water autonomy;
  • Well protected by the solar radiation;
  • In-house ISO17025 calibration laboratory;
  • Accessories for 4-20mA and RS485 output.
