Description
Technical field
The present invention relates to a kind of sensor device, particularly relating to can liquid be bad and body is damaged and a kind of sensor of initiative alarming because connecing.
Background technology
Traditional to judge that sensor connects the bad method of liquid be to measure height of liquid level by installing liquidometer additional, judges whether sensor enters liquid level further according to spot sensor fitting depth, when liquid level is to illustrate that sensor is not in contact with fluid to be measured less than sensor.The fitting depth of sensor is inputted in the program of liquidometer, then send alarm by liquidometer.But could realize when this is also only limitted to be arranged on open river course or pond.For sensor itself whether broken cause bad, the most only visually could find by making regular check on personnel.In use, when liquid level changes, sensor can depart from liquid level to existing ordinary sensors sometimes, causes measurement data invalid.When sensor occurs breakage, and measured value can not conform to the actual conditions yet.And these situations user is in use not easy to find timely.It is important that the data of mistake will bring the water treatment process of mistake that the biggest economic loss, the such as data in field of Environment Protection mistake cause, product rejection that the data of industrial circle mistake cause etc. to user.
Prior art is that sensor is when being arranged on open river course or pond, can by extra increase cost i.e. sensor proximity install additional liquidometer calculate sensor whether with fluid to be measured good contact, not only increase cost, also add the maintenance at scene, defective level measurement scheme also often results in overall plan and lost efficacy, it is impossible to guarantee the effectiveness of measurement data.But whether breakage is necessarily required to by routine inspection just it is found that thus increase maintenance further sensor itself.The sensor installed the most in confined conditions, have no idea at present to realize observing by above method at all, such as it is arranged on the sensor in pipeline, whether the water in pipeline effectively contacts with sensor, whether pipeline inner sensor ruptures all cannot be observed, see unless stopped work to disassemble, this method almost cannot realize in a lot of occasions, even if strengthening inspection dynamics, mistake still cannot be found in the very first time, often the most intact sensor is changed down in order to avoid losing a lot of users, bothersome the most expensive.
Summary of the invention
For solving the insurmountable measuring error caused because of sensor and bad contact of measured medium of above-mentioned ordinary sensors and the problem such as measuring error that sensor breakage causes, the present invention provide can the very first time find sensor whether with fluid to be measured good contact, also can be the very first time to find whether sensor ruptures a kind of sensor of feed liquor.
The present invention solves its technical problem and is adopted the technical scheme that: a kind of sensor, including sensor body, housing and contact rod, the outer surface of described sensor body is provided with housing, described sensor body bottom is for connecing liquid film, the quantity of described contact rod is three, it is respectively the first contact rod, second contact rod, 3rd contact rod, described first contact rod and the 3rd contact rod are arranged on the both sides, inside of housing, described second contact rod is arranged in sensor body, connect between described first contact rod and the 3rd contact rod and have signal circuit, connect between described second contact rod and the 3rd contact rod and have circuit for alarming.
Preferably, described signal circuit is in series by the first contact rod, the first power input, the 3rd resistance, the second photo-coupler, the second light emitting diode, the second resistance and the 3rd contact rod.
Preferably, described first power input is external+24V DC source.
Preferably, described circuit for alarming is in series by the second contact rod, the first resistance, the first light emitting diode, the first photo-coupler, speaker, second source input, the first contact rod.
Preferably, described second source input is external+5V DC source.
Preferably, connecing liquid film described in is glass ball bulb.
Preferably, described contact rod is platinum rod.
Beneficial effects of the present invention: the present invention is in use, when sensor immersed in liquid level, the principle of liquid conduction is utilized at first contact rod of enclosure interior of sensor and the 3rd contact rod, signal circuit between these two contact rods forms path, signal can be externally given with this signal circuit, as lighted display lamp, open measurement, remind user's current measurement value effective；When liquid level is less than contact rod, contact rod separated, display lamp does not works, and reminds user's current level less than sensor, can close measurement.When sensor body lower end connect liquid film damage after, outside liquid enters inside sensor body, the second contact rod in sensor body can be made to form path with the first contact rod in housing, thus circuit for alarming can also light display lamp, reminds user to safeguard in time.It follows that the present invention has fault cues function, and can export control signal, compare relative to traditional method installing liquidometer additional, maintenance is more convenient, cost is lower for it, and is easy to be controlled system, it can be ensured that the reliability of measured value.
Accompanying drawing explanation
The present invention is further described below in conjunction with the accompanying drawings.
Fig. 1 is the overall schematic of the present invention.
Detailed description of the invention
A kind of sensor as shown in Figure 1, including sensor body 1, housing 2 and contact rod 3, the outer surface of described sensor body 1 is provided with housing 2, described sensor body 1 bottom for connecing liquid film 11, described in connect liquid film 11 for glass ball bulb.The quantity of described contact rod 3 is three, it is respectively first contact rod the 31, second contact rod the 32, the 3rd contact rod 33, described first contact rod the 31, second contact rod the 32, the 3rd contact rod 33 is platinum rod, described first contact rod 31 and the 3rd contact rod 33 are arranged on the both sides, inside of housing 2, described second contact rod 32 is arranged in sensor body 1, connecting between described first contact rod 31 and the 3rd contact rod 33 and have signal circuit, being connected between described second contact rod 32 and the 3rd contact rod 33 has circuit for alarming.
Preferably, described signal circuit is by first contact rod the 31, first power input IN1,3rd resistance R7, the second photo-coupler IGN2, the second light emitting diode D2, the second resistance R2 and the 3rd contact rod 33 are in series, and described first power input IN1 is external+24V DC source.
Preferably, described circuit for alarming is in series by second contact rod the 32, first resistance R1, the first light emitting diode D1, the first photo-coupler IGN1, speaker LS, second source input IN2, the first contact rod 31, and described second source input IN2 is external+5V DC source.
The present invention is in use, when sensor immersed in liquid level, contact 33 rods at the first contact rod 31 within the housing 2 of sensor with the 3rd and utilize the principle of liquid conduction, signal circuit between these two contact rods forms path, signal can be externally given with this signal circuit, as lighted display lamp, open measurement, remind user's current measurement value effective；When liquid level is less than contact rod, contact rod separated, display lamp does not works, and reminds user's current level less than sensor, can close measurement.When sensor body 1 lower end connect liquid film 11 damage after, it is internal that outside liquid enters sensor body 1, the second contact rod 32 in sensor body 1 can be made to form path with the first contact rod 31 in housing 2, thus circuit for alarming can also light display lamp, reminds user to safeguard in time.It follows that the present invention has fault cues function, and can export control signal, compare relative to traditional method installing liquidometer additional, maintenance is more convenient, cost is lower for it, and is easy to be controlled system, it can be ensured that the reliability of measured value.
