    T351 Air Temperature Sensor/Screen
    Datasheet: login to download
    • Solar (Sun) Shield
    • Rain Shield
    • Low Cost
    • Light-Weight
    • Compact/Tough

    Our T351-G series Screens/Shields are low-cost, light-weight and compact weather shields/screens for meteorological and industrial applications which can be used to provide protection from the weather for a wide range of probes/sensors including Air Temperature (PRT, RTD, Thermistor, Thermostat etc.) & Humidity (RH) sensors.

    • A deceptively simple design shown to perform well, considering it's small size and low cost, when compared to much larger & more expensive shields/screens during recent WMO (World Meteorological Organisation) trials. Performance is comparable to that of the traditional Stevenson Screen.
    • A compact design allowing free passage of air The naturally ventilated circular louvred design, with white polished surfaces, results in a low temperature rise (error) due to solar radiation by day, and a low temperature drop (error) due to outward radiation to clear skies at night.
    • Mountable to a wide range of poles/masts/towers using our 415 universal mounting arm & fixing-kits.
    • Screen/Shield can easily be opened for access to check/calibrate the probe and/or clean the screen.
    • Also available with RTD/PRT or Thermistor temperature sensing probes, or with HMP110 RH&T probe providing conditioned voltage-outputs for relative-humidity/dewpoint and temperature.
    • Variants available to suit your existing/preferred sensors/probes with diameters between 3 and 17.5mm
    • Some variants also include an internal 'gauze' to protect the probe from raindrops (useful when the probe is a combined temp/RH type).

    T351 Screens for existing probes:
    The T351 is available as the following variants for use with existing probes or other probes of the customer's choice:

    Note that we may be able to offer a customised T351G screen version if the types above are not suitable. All the above screens provide a mounting point, except for the T351-G25 which assumes that the (large) probe has its own mounting arrangements.

    Note that it may be possible to manufacture custom/special screen/probe combinations (using customer's choice of sensing element) if reasonable quantities are required.

    Mounting accessories for the T351 range (not T351-G25) include our 415 Universal Side-Mounting Arm.

    Specification Highlights:

  • Screen Efficiency:
  • 2.3°C/KW/m2 at 1m/s windspeed.
    (temp rise due to solar radiation)
  • Operating Range:
  • -40 to +80°C
  • Max. Wind Speed:
  • over 75m/s (168MPH).
  • Weight:
  • approx. 90g (6-dish screen, without probe).
  • Screen/Shield Fixing:
  • 1/4inch BSW/UNC screw (provided) (excluding T351G25 variant)
  • Shield Materials:
  • Nylon/Polyamide, Polycarbonate, ABS, Aluminium, Stainless-Steel
  • Probe/Sensor Clamping:
  • via Polyamide compression gland (gland size varies with T351-G model)
