Embodiment Construction

[0007] Sensor 105 is used to generate a sensor signal based on sensing the vibrating flow tube. The sampling circuit 101 is used for sampling the sensor signal obtained by sensing by the sensor 105 to obtain a sampling signal. Sensor 105 may be any type of sensor, such as a liquid flow sensor that senses flow, or the like. The processing circuit 102 is configured to process the sampling signal obtained by sampling by the sampling circuit 101 to obtain an output signal. The output signal is a signal that meets the standard required by the subsequent display circuit or controller. The display circuit 103 is used to display the output signal processed by the processing circuit 102 , and the user can observe the signal output by the transmitter through the display. In an embodiment of the present invention, the transmitter 100 is fixedly equipped with a sampling circuit 101, a processing circuit 102, and a display circuit 103 (in figure 1 connected with a solid line). Unlike t...

Abstract

The invention provides a transmitter used for a Coriolis flow meter. The transmitter comprises a sensor and a processing circuit, wherein the sensor is used for generating a sensor signal based on sensing of a vibratory flow tube, and the processing circuit is used for generating an outputting signal based on the sensor signal. The transmitter is characterized in that by further comprising a detachable outputting circuit; under the condition that the outputting circuit is installed on the transmitter, the outputting signal is output through the outputting circuit.

Description

technical field [0001] The invention relates to the technical field of electronic equipment, in particular to a transmitter for a Coriolis flowmeter. Background technique [0002] A transmitter for a Coriolis flowmeter is an instrument that converts a sensor signal obtained by a sensor sensing a vibrating flow tube into a subsequently applicable signal. Such transmitters usually include a display to display the signal transformed by the transmitter. In addition to the display that displays the signal transformed by the transmitter, sometimes an output circuit that outputs the signal transformed by the transmitter (such as outputting the signal to the main control room or computer host) is required, so that Apply this signal to other controls. But this output is not necessary. If the user only wants to observe the signal through the display on the transmitter without using the signal for other control, then the signal does not need to be output. However, in existing transm...
