  • Title: Simple telemetering system for signaling high rumen pressures.
    Author: PAYNE LC.
    Journal: Science; 1960 Feb 26; 131(3400):611-2. PubMed ID: 14431155.
    Abstract:
    The construction of a modified Hartley oscillator transmitter activated through a pressure switch is described. When this device is placed within the rumen of a cow which is allowed unrestricted movement in the pasture, frequency-modulation signals are transmitted to a recording receiver whenever a preselected pressure is exceeded. The pressure at which transmission begins is determined by the capacitance across the coil of the circuit.
