Description
Technical field
It the utility model is related to a kind of fibre optic liquid level sensor.
Background technology
By the fast development of more than ten years, in field of thermal power, with scattered control system (DCS) and fieldbus
Technology (FCS) it is commonly used, automated control technology has obtained tremendous development.Control network facet, current network transmission
Speed has reached 1000M core networks, is 100 times of former 10M networks.In terms of controller disposal ability, at present
Disposal abilities more than 1.4GHz and 200,000 I O points is reached, has been more than 10 times of initial control system.But the hair of e measurement technology
Exhibition but remains in initial state, although the e measurement technology such as pressure, temperature, flow, liquid level is realized in after-treatment link
Digitlization, but Sensor section is without obvious progress.Therefore, common sensor technology has become restriction certainly
The bottleneck of dynamicization technology development.
Utility model content
In order to solve the above technical problems, the utility model provides a kind of fibre optic liquid level sensor.
The utility model is achieved by the following technical programs.
A kind of fibre optic liquid level sensor provided by the utility model, including housing；Pass through flexible sheet point in the housing
For resonator and balancing gate pit, optical fiber collimator is installed on the outer wall of the resonator, the rear end of optical fiber collimator is provided with light
Fibre, the interior side upper end with optical fiber collimator face of resonator are provided with prism, and the bottom of the flexible sheet is set in housing
Rocker piece is equipped with, the lower end of the housing is provided with detection mouth.
The upper surface of the rocker piece is provided with sealant.
The optical fiber collimator is vertically mounted on housing.
It is in 45 ° that the prism, which is arranged on the upper angle of housing and the two side adjacent with housing,.
The detection mouth both ends of the housing are additionally provided with limited block.
The beneficial effects of the utility model are：Because the pressure signal that the present invention provides is continuous light intensity variable quantity,
The output for being input to signal of signal is all by optical fiber transmission, therefore it will not be disturbed by extraneous electromagnetic signals completely, sensing
Device sheet is as essential safe type, therefore this device can apply the measure in substantially any liquid level, and particularly some have
The measure of harmful, inflammable, explosive liquid level.
