Abstract
The invention provides an oxygen converter, which comprises a sensor, a converter, a power interface, a shell, a filter with a stainless steel filter screen, and a relay capable of performing alarm control. The sensor is a tunable diode laser gas spectrometer; the shell is provided with a heated optical surface; the filter can filter impurities in measured gas; and the converter can sense the temperature of ambient environment of the measured gas. The oxygen converter has high stability and sensitivity, can tolerate highly corrosive gas and moist environment simultaneously, and has longer service life.
Description
Technical field
The present invention relates to a kind of oxygen transmitter, belong to the Gas Thickness Detecting Technology field.
Background technology
Accurate and low-cost measurement to oxygen concentration is all significant in fields such as environmental monitoring, biological medicine and industrial energy savings.At different concrete applications, people have been developed various oxygen analysers without kind, and measuring principle mainly is based on solid state electrolysis method, paramagnetic method, electro-chemical cell method, chemoluminescence method etc.Yet above these several technology all are contact measurements, occur easily making the sniffer intoxicating phenomenon in commercial Application, and the sensing probe corrosion-vulnerable, influence the serviceable life of instrument, in use need often calibration could guarantee the accuracy of measuring.
By contrast, have advantages such as noncontact, response speed are fast, long service life based on the oxygen measurement set of laser spectrum tech.Especially the advantage that has good stability, highly sensitive, low energy consumption based on the oxygen determination instrument of tunable diode laser absorption spectroscopy technology (TDL) especially.But the shortcoming of TDL is: in order to realize the measurement to object gas, could satisfy the requirement of this output to the single mode laser diodes laser instrument of light source, and the process complexity of single mode laser diodes laser instrument causes its cost height.In addition, the output wavelength of single mode laser diodes laser instrument is very responsive to variation of temperature, must adopt strict temperature control facility, this has improved the complicacy of system, even and be difficult to also like this guarantee that instrument realizes measurement steady in a long-term in industrial environment complicated and changeable, so limited application based on the oxygen transmitter of TDL technology.
Summary of the invention
The objective of the invention is to solve existing oxygen transmitter based on spectral technique uses single mode laser diodes laser instrument cost height, output wavelength to the temperature variation sensitive issue, a kind of oxygen transmitter of tunable multimode diode laser is provided, it utilizes airborne oxygen as reference gas, realizes the detection to oxygen concentration.
In view of above purpose, the invention provides a kind of oxygen transmitter, comprise sensor, transmitter, power interface, shell, also comprise the filtrator, the transmitter that have the stainless steel screen pack.The tunable diode laser gas spectrometer that this sensor adopts, this shell are the optical surfaces through heating, and this filtrator can filter the impurity in the gas surveyed.This transmitter can be responded to the temperature of the gas surrounding environment of surveying; But this oxygen transmitter also comprises the relay of controlling alarm simultaneously.The present invention has high stability, high sensitivity, can tolerate the gas and the moist environment of highly corrosive simultaneously, longer service life.
Description of drawings
Fig. 1 is the structural drawing of oxygen transmitter of the present invention.
Embodiment
Be the structural drawing of oxygen transmitter of the present invention as shown in Figure 1.This oxygen transmitter comprises sensor, power interface, shell, also comprises: comprise the stainless steel screen pack can filtering gas in the filtrator of impurity; The transmitter of the gas temperature in the energy measurement surrounding environment improves sensitivity and the stability measured.
Further, the sensor senses device in this oxygen transmitter does not have movable part, is not exposed to the element in the tested gas yet; What this sensor adopted simultaneously is tunable diode laser gas spectrometer; This shell is through the optical surface of heating, prevents dewfall, and corrosion resistance is stronger.
Further, this oxygen transmitter also comprises the controlling alarm relay, can improve the security of operation.
Oxygen transmitter provided by the invention is a kind of example and the explanation to the oxygen content measurement device, and unrestricted technical scheme of the present invention.Those of ordinary skill in the art is to be understood that: the present invention is made amendment or is equal to replacement, and do not break away from any modification or partial replacement of the spirit and scope of the present invention, all should be encompassed in the middle of the claim scope of the present invention.
