Abstract
The utility model discloses an improved pH meter sensor. The tail part of the sensor is provided with a floater; a filter screen is arranged outside a glass electrode on the head part of the sensor; a sleeve is arranged outside the filter screen, and used for fixing the filter screen outside the glass electrode on the head part of the sensor; and through holes are uniformly formed on the periphery of the sleeve. When the sensor is used for measuring the pH value of a liquid medium, the pH meter sensor is put in the liquid medium, and the head of the pH meter sensor is protected from damage when the pH meter sensor falls into the liquid medium due to the floater; the filter screen and the sleeve are arranged on the head part of the pH meter sensor, so that solid particles in the liquid medium are prevented from contacting the glass electrode, and precipitate and scaling are prevented; and after the pH meter sensor is used for a period, only the filter screen is required to be changed. The improved pH meter sensor is simple in structure, can effectively protect the head part of the pH meter sensor to facilitate measurement and maintenance.
Description
Technical field:
The utility model relates to pH meter, especially a kind of improved pH meter sensor.
Background technology:
Existing pH meter is made of sensor and converter.Sensor directly contacts with medium solution, and the glass electrode of sensor head is in use damaged because clashing into easily, in addition, for some liquid mediums in producing, easily fouling outside its glass electrode cause the pH value to measure inaccurate, and the dirty utmost point of this layer is not easy cleaning.For the measurement of liquid pH value in the pond, as adopt fixed installation to need again to drop into certain manpower and materials, and safeguard inconvenient.
Summary of the invention:
For the deficiencies in the prior art part, the utility model aims to provide a kind of improved pH meter sensor, and is in use not fragile with the glass electrode of guaranteeing sensor head, and the outer non-scaling of glass electrode,
For solving the problems of the technologies described above, the technical solution adopted in the utility model: a kind of improved pH meter sensor, at the sensor afterbody ball float is set, outside the glass electrode of sensor head, screen pack is set, sleeve is set outside screen pack, sleeve is fixed on screen pack outside the glass electrode of sensor head, and the outer circumference surface of sleeve evenly is provided with through hole.
When adopting improved pH meter sensor measurement liquid medium pH value, only need the pH meter sensor is put into liquid medium, because ball float being arranged, the pH meter sensor is not fallen into because of landing and is damaged head in the liquid medium, and, because the pH meter sensor head is provided with screen pack and sleeve, the solid particle in the liquid medium does not contact with glass electrode, thereby does not just produce precipitation and fouling; After using a period of time, only need to change screen pack.
The utility model is simple in structure, can effectively protect the pH meter sensor head, and it is convenient to measure and overhaul.
Description of drawings
Fig. 1 is the utility model structural representation;
In the accompanying drawing: 1 sensor, 2 screen packs, 3 sleeves, 4 ball floats.
Embodiment
The utility model is described in further detail below in conjunction with accompanying drawing.
As shown in Figure 1, at pH meter sensor 1 afterbody ball float 4 is set, ball float 4 adopts the plastic hollow ball of acid and alkali-resistance, and sensor 1 afterbody passes ball float 4 centers, and ball float 4 housings and sensor 1 afterbody contact site need good seal; Screen pack 2 is set outside the glass electrode of sensor 1 head, at the screen pack 2 outer sleeves 3 that arrange, the outer circumference surface of sleeve 3 evenly is provided with through hole, sleeve 3 is fixed on the head of sensor 1, sleeve 3 is fixed on screen pack 2 outside the glass electrode of sensor 1 head, and sleeve 3 and screen pack 2 are all selected the plastic material of acid and alkali-resistance.
The utility model is used by the clear water reserviors Chinese style at sewage-treatment plant, the head of sensor 1 is not fragile, prevented the fouling of glass electrode, guaranteed the Measurement accuracy of pH meter, prolonged the serviceable life of pH meter sensor 1, and need not to install, dropped in the pond and can use, save erected cost, and maintained easily maintenance.
