Abstract
The invention discloses a temperature detector for a hydro-thermal synthesis reaction still. The detector comprises a signal comparator; and a first thermosensitive probe and a second thermosensitive probe are arranged at the two ends of the signal comparator and are connected with the signal comparator by signal amplifier respectively. One pair of signal output ports is arranged on the signal comparator. The first thermosensitive probe and the second thermosensitive probe are made from thermosensitive ferrite material; and the signal comparator is a zero-crossing voltage comparator. According to the detector, the two thermosensitive probes arranged on the body sense temperatures and resistances of the two thermosensitive probes change; and on the basis of amplification by the signal amplifiers and access of the signal comparator, the internal bridge can convert slight resistance changes of the thermosensitive probes into large signal outputs. Therefore, measurement precision of the temperature detector for the hydro-thermal synthesis reaction still is substantially improved.
