Aspirator Radiation Shield Kit, KIT-ASP™ is an aspirator upgrade to TPH-1 and sensors. It can be installed in the field without any tools.
The integrated fan minimizes the effects of solar heating when wind speeds are low. KIT-ASP can be used for weather instruments or indoor applications, such as HVAC, greenhouse controls, or monitoring of production environments.
Other aspiration systems discharge the air out of the top of the sensor, leading to a risk of recirculating the same air. KIT-ASP uses the mounting pipe of the TPH sensor as a duct to exhaust the air away from the sensing elements.
When used with Dyacon control modules on MS-100 series weather stations, the aspirator fan utilizes Smart-FanTM technology to run the fan only when solar radiation is detected. This allows the aspirator to run efficiently with on solar powered stations.
A 24 VDC version is also available when the aspirator is used with industrial automation systems.
- 12 VDC power (24 VDC option)
- Ball-bearing, brushless fan
- 7800 rpm, 9 CFM
- Smart-FanTM (Dyacon control module required.)
Please note that this is a upgrade to TPH sensors only and does not include a sensor. Refer to TPH-1 for Dyacon sensors that include the radiation shield and sensor.
