FIELD: thermometry; contact temperature detectors.
SUBSTANCE: temperature detector can be used in oil and chemical industry and in public services. Temperature detector has carrier tube fixed inside pipeline by means of union. Tube has thread connection with sleeve. Temperature-sensitive element is fixed in sleeve. Temperature-sensitive element has to be quartz resonator which has its outputs connected with frequency oscillator circuit. Frequency oscillator is mounted on printed circuit disposed inside tube. Free space between quartz resonator and internal wall of sleeve is filled with heat-conducting material. Printed circuit is connected with external circuits by means of cable. Union and sleeve have internal thread. Carrier tube has external thread.
EFFECT: simplified design; improved precision of measurements.
