Title: Electronic automatic temperature control
Inventor: GRIFFITH ROBERT C
IPC: G05D23/24
Filed: 1992-08-25
Granted: 1998-07-28
Abstract: A  temperature  control  circuit  is  disclosed utilizing automatically either the electric heating (or cooling)  element  or  a  separate  sensor  to measure  the instantaneous temperature of a thermal load device (40).     Either a pulsating de or an ac electric power source (16) may be  used with the  temperature  sensing occurring at near-zero points of  the  source voltage waveform.   The sensor (68) forms one element of a Wheatstone bridge (90) which when unbalanced  by a value  lower than a chosen reference value,  causes a monostable oscillator (70) to flip for at least  several cycles of the source power.          This turns on a power SCR (42) to feed electric current to  the  thermal  load  to  increase  its  temperature  (and resistance) until the bridge is again balanced to reverse the state of the monostable oscillator and turn off the SCR.     A  simple,  reliable  two  step,  user  friendly calibration  circuit  is  provided  for  the  temperature selecting component.   For multiple channel applications the circuit need be reiterated only in part whereby major portions thereof remain common to the various channels and   need   not   be duplicated,   thereby   minimizing manufacturing cost, component space, heat generation, and power consumption.
