Abstract
The utility model discloses a far transmitted electron two-tone liquidometer and belongs to the technical field of auto control meters. The far transmitted electron two-tone liquidometer comprises a light-emitting diode (LED) display screen, a liquid level detecting resistor, a central processing unit (CPU) and a voltage-to-current (VI) converter. The liquid level detecting resistor is connected with a signal input end of the CPU. A displaying output end of the CPU is connected with an LED display screen input end. A voltage output end of the CPU is connected with a voltage input end of the VI converter. Compared with the prior art, the far transmitted electron two-tone liquidometer has the advantages that a red-green LED shining strip is used for displaying the liquid level of the liquidometer, and the displaying is very clear; furthermore, signals of 4-20 milliamperes can be output in converted transmission so as to be connected with a water level regulator to achieve automatic adjustment of water levels; the signals can be transmitted to display on a meter or an upper computer. The far transmitted electron two-tone liquidometer is convenient to use.
Description
Technical field
The utility model belongs to the automatic instrument(s) technical field, particularly a kind of teletransmission electronic double-colored liquid indicator.
Background technology
At present, the magnetic turnover panel is to lean on the color of turnover panel to show water level in the magnetic turnover panel water-level gauge of boiler drum level demonstration usefulness, in the environment of boiler room dark, be not easy to see clearly, and magnetic turnover panel water-level gauge do not become and send function, if need the remote liquid level signal, and dosing position transmitter in addition, cause like this equipment complicated, exist expense to increase, accuracy reduces, ineffective shortcoming.
Summary of the invention
The utility model provides a kind of teletransmission electronic double-colored liquid indicator for the deficiencies in the prior art, has reached the purpose of accurate measurement.
The technical solution adopted in the utility model, comprise that LED display, liquid level detect resistance, CPU and VI converter, wherein liquid level detects the signal input part that resistance connects CPU, the demonstration output terminal of CPU connects the input end of LED display, and the voltage output end of CPU connects the voltage input end of VI converter.
The utility model compared with prior art beneficial effect is: this liquid level gauge is by using red and green color LED light-emitting section to show liquid level, it is very clear to show, and can become and send output 4 ~ 20mA signal, be convenient to connect water-level regulator and realize automatically regulating water level, also can pass the signal to instrument or host computer and show, very easy to use.
