Thermally Stable Telemeter for Thermoregulation Studies

Abstract

Of the numerous designs published for temperature biotelemeters, not one is suitable for external mounting on animals which are subject to considerable fluctuations in their environmental temperature. A transmitter has been developed which is simple and insensitive to changes in environmental temperatures between 10 degrees and 50 degrees Celsius; it emits a pulsed, narrow band-width signal in the 0.5 to 2 megahertz band.
