Description
Technical field
Collection and the output field of industrial process signal are the utility model is related to, particularly relates to a kind of temperature transmitter.
Background technology
Traditional temperature sensor such as thermal resistance, thermocouple, its output signal are the thermal resistance resistance signal or electricity of standard
Signal is pressed, in measurement process, if the circuit at temperature sensor and reception signal end is farther out, output signal is influenceed by line resistance
Seriously, accuracy of measurement is low, poor reliability.To solve the above problems, often installing a temperature transmitter additional on temperature sensor, have
Body, a meter housing is fixed on temperature sensor top, and temperature transmitter is locked in the meter housing by bolt.Temperature transmitter
It is a kind of instrument that the temperature variable of temperature sensor senses is converted to transmittable normalization output signal, it can be by resistance
Signal or voltage signal are transformed into the analog signal of standard（Such as mA signals）, asked with solving measurement signal by what line resistance was influenceed
Topic.Existing temperature transmitter, its structure generally include transmitter body, and two through hole is opened up on transmitter body, and two bolts pass through
Two through hole is locked on meter housing.In industrial production, industrial operations are generally along with vibration, correspondingly, temperature sensor and thereon
Most of fixed temperature transmitter need to be installed in the equipment of vibration in meter housing, such as industrial pipeline, to carry out industrial process
The measurement of temperature parameter, however, the problem of signal loose contact easily occurs for temperature transmitter under vibrational state, and then cause to measure
The appearance of deviation, temperature transmitter can even release and drop and can not use during long-term work.
The content of the invention
The purpose of this utility model is to provide a kind of temperature transmitter.
Realizing the technical scheme of the utility model purpose is, a kind of temperature transmitter, including transmitter body, transmitter sheet
Through hole is offered on body, through hole includes the upper hole section of connection and lower hole section, and the aperture of upper hole section is more than the aperture of lower hole section, a spiral shell
Bolt is locked in sensor apparatus shell after sequentially passing through the through hole of a stage clip and transmitter body, and the external diameter of stage clip is more than lower hole section
Aperture.
Further, the external diameter of stage clip is less than the aperture of upper hole section, and stage clip is located in the upper hole section of through hole.The utility model
The setting, on the one hand, through hole can be realized to the spacing of stage clip, avoid stage clip from offseting and produce shearing between bolt and bend,
Influence the effect of its buffer shock-absorbing；On the other hand, stage clip is located in the upper hole section of through hole, and compared to the structure positioned at through hole, its is total
Height can be reduced effectively, facilitate the installation in sensor apparatus shell.
Further, transmitter body is provided with USB interface.Temperature transmitter, can be with computer or hand by USB interface
Hold programmable device to be communicated, in this way, to be operated by computer or hand-hold programmer to temperature transmitter, change temperature and become
The setting of device is sent, such as the signal of collection is switched over, and then temperature transmitter is suitable for the application in more places.
Further, instrument connection is additionally provided with transmitter body., can basis for the important signal of transmitter body inner segment
Need, by instrument connection at any time, repeatedly carry out detection checking, it is ensured that the high reliability of temperature transmitter.
The utility model temperature transmitter, by setting stage clip between bolt and transmitter body, make with sensor apparatus
The bolt of shell vibration active force caused by because of vibration is not directly placed on transmitter body, but after stage clip transition digestion,
Transmitter body is transferred to, so that transmitter body stress is small, Oscillation Amplitude is small, and stage clip realizes the effect of buffer shock-absorbing, has
Effect is avoided in industrial process temperature parameter measurement process, warm transmitter because vibration and caused by signal loose contact or release
The phenomenon fallen.
