Weather stations by Peet Bros.

Everybody talks about it, everybody is affected by it - the weather. Do I need the heavy coat today, or is a wind breaker sufficient? Should I take the umbrella or not? Observing the weather is a fascinating occupation for all nature lovers and a very interesting extension to the hobby, not only for radio amateurs. So what's more obvious than to install your own weather monitor?

Peet Bros. company is a manufacturer of premium weather stations. The offered systems differ vastly from the cheap weather displays which you find at any department store - in quality and in the nearly endless possibilities. The sensors are individually made and hand calibrated for best accuracy. A large number of options allows you to build up your personal weather station up to a nearly professional system.

Overview Peet Bros. Weather stations

Peet Bros. offers three basic models of weather stations: the Ultimeter® 100, Ultimeter® 800 and Ultimeter® 2100. The capabilities and possible options for each device is shown in the table below.

Wind vane and anemometer (Pro version) included
With each Ultimeter weather station a reliable weather vane, an anemometer (Wind speed, 'Pro' version)) and an outdoor thermometer is included. An optional rain gauge can be connected to any of the models. Further sensors can be connected to the model 800 and 2100.

Anemometer Wind Vane Supplied: Vane and Anemometer

Long term menory
The long term memory offers the possiblity to record min. and max. values over a longer time period and recall them on request. Nine memories record the daily extremes, those of the last 7 days amd one more permanent record.

Connection of sensors
Like with all professional weather equipment, the sensors are connected by cable, and not wireless. This results in much better reliability and faster update rates. All sensors are connected to a central junction box, which also supplies all devices with power. The computer or APRS radio can be connected to the junction box or to the display unit.

Long cables supplied
All units and options come with extra long cables for ease of installation: 12m for the wind vane/anemometer, 7.5m for the outdoor temperature sensor. The cable between the junction box and the disply/keybiard unit is 240cm long, the power supply cable 180cm. Alle data cables can be extended very easily and to nearly any length, if required.
The wind vane/anemomenter is best installed on top of a mast (not to the side), we are happy to offer you a suitable mast tube. Since this sensor works with magnetic reed contacts a non-magnetic tube is preferred (aluminium, stainless steel or similar).

Ideal for APRS:
Several APRS ready radios, like the new Kenwood TM-D710E offers a direct connection for Peet weather stations. Go on the air in no time with your personal APRS weather broadcast. Works also with WxTrak APRS for practically any other radio, or with a usual Packet Radio TNC.

Of course all Peet Weather Stations are suitable for european power systems, a 230V power supply is included. The units of all weather data is selectable, for example °C or °F, metric system, nautical system or imperial system for other values.
For permanent backup of settings and long term memories a 9V block batteryis required (not included).

TB Rain Gauge for Ultimeter 100, 800, 2100

Ultimeter TB Rain Gauge

The ULTIMETER TB Rain Gauge features a proven tipping bucket design. Inside each rain gauge is a balanced "see-saw" bucket mechanism. The bucket has a divider wall across the middle, separating it into two halves, each shaped like a miniature coal shovel, with high sides and an open end. The rain gauge's funnel top feeds rain water into one of the half-buckets. As soon as the correct amount of water has been collected, the "see-saw" tips the other way, automatically emptying the water and positioning the other half-bucket for collecting rainfall. Each time the bucket tips, .01" of rainfall is added to the accumulated total on the ULTIMETER weather station. 8-inch diameter collector funnel, for superior rainfall sampling.

Difference between the two rain gauges

The manufacturer writes about the differences of the two rain gauges:

The WSF-10100 is the smaller of the two, and responds to rainfall in .001"/.0254 mm (but records in .01"/.254mm). The WSF-10200 responds and records in .01"/.254mm.

The major difference, though, is that the -10100 operates on a "drop counting" principle, with no moving parts, but has a drop sensor tube that requres regular cleaning as preventive maintenance. The -10200 is a classic "tipping bucket" design, which is mechanically simple for the customer to understand (and troubleshoot, if necessary), and has no particular maintenance required other than to occasionally clear the funnel of debris (leaves, bird deposits, etc.).

We usually recommend the -10200 for institutional/government customers, or any customer who prefers to "install and forget", because it is the more forgiving of neglect. I use a -10200 at my home, because I am surrounded by large oak trees that continually drop debris into the rain gauge, so that I do not have to clean it as often.

The ULTIMETER Temperature Sensor is a precision aged interchangeable thermistor. Designed for under-eaves mounting, out of direct sun exposure.

  • The exceptional long-term stability of the humidity sensor element means years of use without recalibration.
  • Operates over the full humidity range, from 0% to 100% R.H.
  • Temperature range is -48 to +66°C.
  • Includes 12m cable and mounting hardware (longer cable lengths optional).

Single Cable Kit

Single Cable Kit
Wiring diagram Single Cable Kit

Usually the outdoor sensors are connected with one cable each to the indoor junction box. So that's two or three flat, small cables which have to be fed through the wall. If that is not possible the "Single Cable Kit" helps. Here a weatherproof outdoor junction box is used to collect all cables from sensors, one cable leads indoors.

Note: The Single Cable Kit does not contain cables. You need one extra cable from outdoor junction box to indoor display unit! Usually a normal 8 wire Ethernet cable can be used.

When using a 10 wire RJ45 cable, the two additional wires offer the possiblity to connect the serial interface of the indoor unit with the outdoor unit. This feature is available, but is needed only in rare cases. If, for example, a APRS-digi needs to be fed with serial data, cabling can be reduced significantly.
