TOWNSEND SUPPORT: A common support used to fixture maximum and minimum thermometers. It is designed to hold the thermometers at the proper angles for measuring, and it also simplifies resetting of the thermometer markers.
See Townsend support. Thermopile A transducer for converting thermal energy directly into electrical energy. It is composed of pairs of thermocouples which are connected either in series or in parallel.
Townsend Support: A metal support whichs hold the maximun & minimum thermometers.
TR Switch: Weather Radar Transmit/Receiver Switch which switches between transmit and receive modes.
Trace Of Precipitation: Less than .01 inch.
thermometers with a circular scale are also used as maximum thermometers. A free index mounted concentrically with and driven by the thermometer index is held by friction at the maximum temperature. Compare minimum thermometer; see Townsend support.
