Description
Technical field:
The present invention relates to measure in a kind of water treatment field the water ion sensor of electrical conductivity of water.
Technical background:
In water treatment field, electrical conductivity of water is whether very important index up to standard of assessment water quality.There is following defective in traditional water ion sensor: one, because electrode material mostly is stainless steel or titanium alloy, can't directly weld with copper or the silver-colored material of wire; Though if electrode and conductor material all select silver-colored material to weld but cost is too high.So the electrode of present survey sensor and wire all adopt compression joint technique.Cause the contact resistance of water ion sensor large, and resistance is unstable.Must calibrate when the water ion sensor is installed, and be difficult to accomplish precision measurement.Two, the potential electrode spacing of conductivity requires very strict.And present water ion sensor all adopts plastic package.Because shrinkage factor and the impact of expanding with heat and contract with cold in the water ion sensor process, the electrode separation error is larger.Must calibrate when the water ion sensor is installed, and be difficult to accomplish precision measurement.Three, because the measuring-signal of water ion sensor is very faint, and be non-standard simulating signal.Be very easy to be interfered, and transmission range is not more than ten meters.So can't remote monitoring on-the-spot water quality can only be maked an inspection tour field instrument by personnel.
Because there is defects in traditional water ion sensor, is difficult to satisfy water treatment field to the needs of higher development.
Summary of the invention:
The purpose of this invention is to provide and a kind ofly can realize high-acruracy survey, need not to calibrate and water ion sensor that can remote monitoring.
For achieving the above object, the present invention takes following design proposal:
The water ion sensor has anodal and two electrodes of a negative pole, welding one transition metal on the every electrode, the other end of transition metal and wire bonds, the other end of wire is connected with modular converter, one end of modular converter and two electrodes is fixed with housing, the output terminal of modular converter is by the wire output signal, and screen layer one end of the wire of output signal is connected with the metal screen case of enclosure interior.
Described transition metal and electrode material and conductor material all can good welds.
Described modular converter places the inside of sensor or places sensor outside.
Described modular converter is converted at least a in following digital interface and the standard analog signal with the analog signals that gathers: RS485 communication interface, RS232 communication interface, RS422 communication interface, ethernet communication interface, USB communication interface, binary signal interface, voltage-type standard analog signal, current mode standard analog signal.
Described housing is selected epoxide resin material.
Described metal screen case places the inside of housing or places outside.

Accompanying drawing is water ion sensor construction synoptic diagram of the present invention.
Below in conjunction with accompanying drawing the present invention is described in further details:
Embodiment
As shown in drawings, water ion sensor of the present invention adopts traditional anodal and two electrodes 1 of a negative pole.In order to make electrode 1 and wire 3 weld to reduce contact resistance, up-to-date employing electrode 1 welds a transition metal 2 with wire 3 links, an end of transition metal 2 and electrode 1 welding, the other end and wire 3 welding.In order to reduce the impact of disturbing sensor accuracy, add again a modular converter 4.The analog input end of modular converter 4 is connected with the other end of wire 3, and it is strong that the analog signals that electrode 1 is gathered is converted to anti-interference energy, can long-distance transmissions, and can be easily and digital quantity and the mock standard signal of host computer or instrumentation tap.The output terminal of modular converter 4 connects wire 8, by wire 8 output digital quantity signals.In order further to reduce the impact of disturbing sensor accuracy, screen layer 7 one ends with the wire 8 of output signal are connected with the metal screen case 5 of housing 6 inside again.
Described modular converter 4 is converted at least a in following digital interface and the standard analog signal with the analog signals that gathers: RS485 communication interface, RS232 communication interface, RS422 communication interface, ethernet communication interface, USB communication interface, binary signal interface, voltage-type standard analog signal, current mode standard analog signal.
Described housing selects that intensity is high, shrinkage factor is low, anti-long-term hydrolysis, epoxide resin material that dielectric strength is high, makes two electrode separation precision positionings.
Above-described embodiment can not depart from the scope of the present invention lower in addition some variations, thus above explanation comprises and accompanying drawing shown in structure should be considered as exemplary, but not in order to limit the protection domain of the present patent application patent.
