Stably-connected integrated transmitter capable of testing surface temperature

Abstract

The invention relates to the technical field of transmitters, and discloses a stably-connected integrated transmitter capable of testing surface temperature. The integrated transmitter comprises a panel header, wherein a wiring terminal is fixedly arranged at the right side of the panel header; a head connecting piece is fixedly arranged at the bottom of the panel header; a heat dissipation ring is fixedly arranged at the bottom of the head connecting piece; air supply pipes which are bilaterally symmetrical is fixedly arranged inside the heat dissipation ring; connecting pipes communicating with the air supply pipes are respectively fixedly arranged in the heat dissipation ring; inserting holes communicating with the connecting pipes are arranged in the heat dissipation ring; and fixing blocks which are arranged at the opposite sides of the two inserting holes are fixedly arranged in the heat dissipation ring. The stably-connected integrated transmitter capable of testing the surfacetemperature has the advantages of being stable in installation, convenient to dissipate heat and the like, and solves the problems that the transmitter is inconvenient to disassemble, precise components in the transmitter generate heat in a working process and are difficult to dissipate and cool in the prior art.

Description

technical field [0001] The invention relates to the technical field of transmitters, in particular to an integrated transmitter connected to a stable test surface temperature. Background technique [0002] The transmitter is developed from the sensor. For any sensor that can output standard signals, the standard signal refers to the signal whose physical quantity conforms to the international standard in form and quantity range. Because the DC signal is not affected by the inductance, capacitance and load properties in the line Therefore, the International Electrotechnical Commission (IEC) determines the current signal 4mA ~ 20mA (DC) and the voltage signal 1V ~ 5V (DC) as the unified standard for the analog signal in the process control system. The measurement part It is used to detect the measured variable x and convert it into an input signal Zi (voltage, current, displacement, force or torque, etc.) that can be accepted by the amplifier, and the feedback part converts th...
