The device comprises a plurality of stainless steel wire pairs, a PLC input module and a transformer, and is characterized in that each stainless steel wire pair consists of a first stainless steel wire and a second stainless steel wire; one end of each first stainless steel wire is arranged in high-temperature water, and the other end of the first stainless steel wire is connected with one end of a secondary coil of the transformer; the other end of the secondary coil of the transformer is connected with a common terminal of the PLC input module; one end of each second stainless steel wire is arranged in the high-temperature water, and the other end of the second stainless steel wire is connected with a corresponding input port in the PLC input module; the transformer is an AC (Alternating current)-AC transformer. Compared with the prior art, the device has the characteristics of being simple in structure, long in detection service life, reliable in operation, low in cost, convenient to mount and the like, solves the problems that a traditional water level switch, adopted to detect water level of high-temperature water, is short in service life and poor in reliability, and meets the requirement of high-temperature water for water level control occasions.
Description
Technical field
The present invention relates to a kind of condensate tank of dehumidifier, particularly relate to the water level detecting for high-temperature water.
Background technology
In water level control system, commonly use the feedback signal of water level switch as water level.In the market, conventional water level switch has: condenser type water level switch, electronic level switch, photo-electric water level switch, tuning-fork type water level switch, float-ball type water level switch etc.Their common drawback is to service condition and has requirement, is generally difficult to realize detecting for a long time to high-temperature water (as 80 DEG C and above boiling water) water level.Tracing it to its cause is conventional water level switch detecting electrode used, and in logical direct current and high-temperature water environment, galvanic corrosion consumes quickly, and then it is general lower to detect the life-span.
Summary of the invention
Embodiments of the invention object is to provide a kind of high-temperature water condensate tank of dehumidifier, there is the features such as structure is simple, detection life-span length, reliable operation, adopt traditional water level switch when carrying out water level detecting to high-temperature water to solve, the problem of life-span low, poor reliability, meets high-temperature water water lev el control application requirements.
For achieving the above object, embodiments of the invention adopt following technical scheme:
A kind of high-temperature water condensate tank of dehumidifier, if be made up of stainless steel steel wire group, PLC output module, transformer individual, it is characterized in that: if individual to the every a pair stainless steel steel wire group in stainless steel steel wire group, by 1 first stainless steel steel wire, 1 second stainless steel steel wire composition; First described stainless steel steel wire one end is arranged in high-temperature water tank, and the other end is connected with secondary coil one end of described transformer, and the secondary coil other end of described transformer, is connected with the public port of PLC output module; Second described stainless steel steel wire one end is arranged in high-temperature water tank, and the other end input port corresponding in PLC output module connects; Described transformer becomes AC system transformer for exchanging.
As optimization, first, second described stainless steel gauge of wire is φ 1 ~ φ 4.
As optimization, outside at first, second described stainless steel steel wire, be provided with insulation course, to realize electric protection.
Principle of work of the present invention: after tested, on most PLC input end, input port can accept the ac signal (input port usually accesses the use of 24V direct current signal in PLC control loop) of certain amplitude voltage, can form alternating current water level detecting loop by input port corresponding in the first stainless steel steel wire, the second stainless steel steel wire, PLC output module, the secondary coil of transformer, the common port of PLC output module.If high-temperature water water level reach the first stainless steel steel wire, the second stainless steel steel wire enter water level when putting, the loop conducting of alternating current water level detecting, then can make corresponding input port in PLC output module still can arrive reliably water level detecting signal.Because stainless steel material is under indirect current condition, the substantially production galvanic corrosion and produce consumption by the impact of high-temperature water environment, therefore ensure that serviceable life.
A kind of high-temperature water condensate tank of dehumidifier provided by the invention, make use of corresponding input port in PLC output module and can accept the AC signal of certain amplitude voltage as input port signal, stainless steel steel wire does not substantially produce the principle that galvanic corrosion consumes in the high-temperature water of indirect current, and stainless steel steel wire, AC transformer, PLC output module are combined into condensate tank of dehumidifier.Compared with prior art, the present invention have structure simple, detect life-span length, reliable operation, the feature such as with low cost, easy for installation, solve and adopt traditional water level switch when carrying out water level detecting to high-temperature water, the problem of life-span low, poor reliability, meets high-temperature water water lev el control application requirements.
