Abstract

The invention discloses a temperature transmitter suitable for a low-temperature environment. The temperature transmitter comprises a thermistor, the thermistor is prepared from, by weight, 10-20% oflanthanum oxide, 10-20% of titanium dioxide, 10-20% of manganese dioxide, 5-15% of nickelic oxide, 10-18% of chromium sesquioxide, 5-15% of strontium carbonate, 4-10% of lead telluride and 4-10% of cadmium sulfide. According to the temperature transmitter suitable for the low-temperature environment in the technical scheme, the thermistor formed according to the proportion of the various compositions achieves good temperature detection precision and stability in the low-temperature environment, and therefore the overall usage effect of the temperature transmitter in the low-temperature environment is improved.

Description

technical field [0001] The invention relates to the field of electronic technology, in particular to a temperature transmitter suitable for low-temperature environments. Background technique [0002] A transmitter is a device that converts a physical measurement signal or an ordinary electrical signal into a standard electrical signal output, or outputs it in a communication protocol. The temperature transmitter is one of the common transmitters, which is used to detect the temperature change state in the environment. Existing temperature transmitters cannot achieve good detection accuracy and stability in low temperature environments. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a temperature transmitter suitable for a low temperature environment, which can achieve good temperature detection accuracy and stability in a low temperature environment. [0004] In order to solve the above technical problems, the...
