The capacitance type sensors and the glass pipe water level gauge are fixed through a bonding band, the capacitance type sensors are connected with a measurement and judgment alarm unit, and the measurement and judgment alarm unit is provided with an interlocking contact and an alarm. The number of the pointing cavities is more than two sets, and the number of the capacitance type sensors is more than two sets. Compared with the prior art, the monitoring alarm device of the glass pipe water level gauge has the advantages that operation is simple, cost is low, the water level of the water level gauge can be accurately monitored, and sound-light alarming and interlocking signals are given out.
Description
Technical field
The utility model relates to a kind of glass tube water level gauge monitoring alarm, especially a kind of glass tube water level gauge monitoring alarm that points to cavity that is provided with.
Background technology
At present, the demonstration of the water level of miniature boiler, adopts glass tube water level gauge mostly, and glass tube water level gauge is easy to use, observation is directly perceived, low price, but can not directly be converted to electric signal, can not be chain with warning device.On market, the electrical signal detection of container and the product of warning have a lot, but the complicated and common stoker personnel of high, the supporting control system of price are difficult to association, use.So, for the particularly water level monitoring warning of miniature boiler of small-sized closed container, also there is no cheap handy product.
Summary of the invention
Technical assignment of the present utility model is the weak point for above present situation, and a kind of low price is provided, simple to operate, monitors glass tube water level gauge monitoring alarm accurately.
The utility model solves technical scheme that its technical matters adopts: structure of the present utility model comprises glass tube water level gauge, pointing to cavity is hollow housing, hollow one end arranges capacitance type sensor, the hollow other end abuts against on glass tube water level gauge outer wall, with strapping, pointing to cavity and capacitance type sensor and glass tube water level gauge, be fixed together, capacitance type sensor connects measures judgement alarm unit, measures on judgement alarm unit interlocking contact and alarm are set.
Described sensing cavity and capacitance type sensor quantity are more than two groups.
The utility model detects by sensor the capacitance size that water level causes to be changed; Measure judgement alarm unit according to the initial value of setting, change, have the difference between water and anhydrous difference, sensor, by single-chip microcomputer, accurately calculate judgement water bit position, and according to water level settings value, provide the output of warning and interlocking signal.
Glass tube water level gauge monitoring alarm of the present utility model compared to the prior art, there is following characteristics: the utility model by arranging the capacitance type sensor of non-contacting survey water level on glass tube water level gauge outer wall, just can make to measure and there is directivity, set up is 2 above sensors simultaneously, strengthened the ability of getting rid of interference, detected effective; The utility model is simple in structure, and cost is low, easily operation.
Accompanying drawing explanation
Below in conjunction with accompanying drawing, the utility model is further illustrated.
Accompanying drawing 1 is a kind of structural representation of glass tube water level gauge monitoring alarm.
Accompanying drawing 2 is circuit block diagrams of a kind of glass tube water level gauge monitoring alarm.
In figure: 1, glass tube water level gauge, 2, capacitance type sensor, 3, point to cavity,, 4, strapping, 5, measure judgement alarm unit, 6, interlocking contact, 7, alarm.
Embodiment
With reference to Figure of description, glass tube water level gauge monitoring alarm is described in detail below.
Glass tube water level gauge monitoring alarm of the present utility model, structure comprises glass tube water level gauge 1 parts such as grade.Pointing to cavity 3 is hollow housings, can be hollow cylindrical, can be also hollow rectangle or square.Hollow one end of pointing to cavity 3 arranges capacitance type sensor 2, and while manufacturing, both make an integral body.The hollow other end abuts against on glass tube water level gauge 1 outer wall, with strapping 4, pointing to cavity 3 and capacitance type sensor 2 and glass tube water level gauge 1, be fixed together, can guarantee like this better effects if detecting: 2 SEA LEVEL VARIATION that detect the hollow sensing position of pointing to cavity 3 of capacitance type sensor, can not detect and point to position water level in addition, can the misoperation because of water vapor in incrustation scale or tube wall attached water or pipe yet.Capacitance type sensor 2 connects measures judgement alarm unit 5, measures on judgement alarm unit 5 interlocking contact 6 and alarm 7 are set.Interlocking contact 6 can be connected with electric interlocking installation in use, and the electric signal of interlocking is provided.
Described sensing cavity 3 and capacitance type sensor 2 quantity are two groups.Be separately positioned on the position that glass tube water level gauge upper/lower terminal is suitable.When boiler operatiopn is normal, be respectively used to sensed water level in respect of water section and the anhydrous part of water-level gauge; In operational process, the relatively detection by two sensor electrical signals has water or anhydrous variation, provides signal to measuring judgement alarm unit 5, and the accurate judgement that draws operation conditions, realizes the balance filtering to interference factor in water level detecting.
Described sensing cavity 3 and the quantity of capacitance type sensor 2 also can be set to more than three groups.
Described strapping 4 is the high temperature resistant strapping of teflon.
The utility model is capacitance type sensor to be applied to the detection of water level, and having broken through traditional capacitance type sensor only can be for detection of the field of the change location of metal.
The utility model low cost, is applicable to the water level of the low pressure vessels such as miniature boiler to carry out non-contact detecting and warning, can improve the security of boiler operatiopn.
