Abstract
The utility model relates to a measuring transducer, particularly to a transducer which can measure the amount of sulfate reducing bacteria (SRB) in seawater. The utility model is composed of an insulated outer shell, a transducing film sheet, a reference electrode, an electrode cap and a sealing layer, wherein the insulated outer shell forms a cylinder shape. One end wall of the insulated outer shell is provided with round holes, and one silver transducing film sheet is arranged much near to the end. The sealing layer is arranged below the transducing film sheet. The reference electrode is arranged in the insulated outer shell. The free end is positioned at the point with the distance of two to four times away from the diameter of the transducing film sheet, and the other end is arranged on the electrode cap. The transducing film sheet and the reference electrode are respectively led out from the other end of the insulated outer shell by shielded wires, are sealed and fixed by the electrode cap, and are connected with a millivoltmeter or other apparatuses which can measure electric potential. The utility model has the advantages of convenience and speediness, can realize in-situ measurement, and has short test periods.
Description
Technical field
The utility model relates to survey sensor, specifically is the sensor of sulphate reducing bacteria (SRB) quantity in a kind of energy measurement seawater.
Background technology
At present, generally the method for the measurement SRB of Cai Yonging is the MPN method, promptly adopt many test tubes fermentation technique, measurement mechanism is an incubator, in incubator, cultivated 21 days in 29 ± 1 ℃, according in vitro producing black precipitate and sulfuretted hydrogen stink situation, adopt maximum possible counting method (MPN method) that the SRB quantity in the sample is counted.The shortcoming of this measuring method is to realize in site measurement and test period long (cultivating 21 days).
The utility model content
In order to overcome the deficiency of existing SRB measuring method, the utility model provide a kind of convenient and swift, can realize in site measurement and test period short sulphate reducing bacteria survey sensor.
The technical scheme that the utility model adopted is: it is by insulation crust, pressure-sensitive diaphragm, contrast electrode, electrode cap, sealant is formed, wherein: described insulation crust is cylindric, be laid with circular hole on the one end wall, near this end a silvery pressure-sensitive diaphragm is housed, sealant places the pressure-sensitive diaphragm below, contrast electrode is installed in insulation crust, its free end is positioned at apart from the pressure-sensitive diaphragm diameter to be located for 2～4 times, the other end is installed on the electrode cap, pressure-sensitive diaphragm and contrast electrode are drawn from the other end of insulation crust by shielded conductor respectively, and, link to each other with millivoltmeter or other instrument that can measure current potential by the electrode cap sealing and fixing;
Described contrast electrode can be selected for use and use the silver halide contrast electrode in the seawater; Described circular hole can evenly be laid on insulation crust one end wall; Described sealant can adopt the epoxy sealing material.
The utlity model has following advantage:
Because the utility model will link with millivoltmeter or other instrument that can measure current potential, by the SRB content in the voltage output value measurement seawater of the utility model survey sensor, this measuring method is measured rapidly, use very convenient, and can realize in site measurement and test period short (the utility model immerses in the tested seawater, can measure the potential value of different SRB concentration correspondences and draw calibration curve in 2～3 minutes after solution-stabilized).
