6) S: Shield is an abbreviation for shielding the radio waves or magnetic fields that have a negative effect on the signal.

7) T: Abbreviation of temperature. If the terminal is 2-wire (2-wire), it can be connected to T or T. The purpose of using the wire is to add the wire resistance to the resistance value so that it can be used when the wire resistance is small or when the temperature resistance needs to be set in advance.)

8) T1, T2: It stands for temperature and it is used when the temperature measurement part is 3-wire type (3-wire type) or 4-wire type (4-wire type). In case of 3-wire type, When a more precise temperature measurement is required compared to a two-wire system, one of the two strands of the temperature sensor is connected to one another to form two wires, T1 and T1, and one other strand is referred to as T2.

That is, for example, if the temperature element is Pt100, 100 ohms is measured at 0 ° C even if T2 is connected to any two T1s. The resistance according to temperature is measured, and the measurement between T1 and T1 forms an infinite resistance value . The 4-wire type does not affect the wire resistance, so it represents the part used for temperature measurement of very high accuracy.

Characteristics by manufacturer  There is a problem that the manufacturing method of the water quality sensor is different according to each maker, and the form and configuration of the terminal block are not uniform.  It is manufactured differently from other manufacturers, but the measuring electrode, the reference electrode or the oxidizing electrode, the anode, the reducing electrode or the cathode, the temperature sensor, the grounding function and the wiring connected for the shielding function are always made in the same manner. It can be easily judged by expressing characteristics and it is characteristic that standardization of terminal block is made. The terminal characteristics are indicated on the meter terminals in different ways.
Conventional sensor terminal block has a problem that it is difficult to properly connect the sensor terminal by making the wiring of the sensor different according to the maker and seeing the indication of the meter terminal.
On the other hand, the standard terminal block of the present invention is characterized by a marking portion formed for each wiring and a simple comparison with a meter terminal.







Characteristics according to manual  There is a problem that it is necessary to verify the characteristics of the sensor terminal block by looking at the meter terminal and the meter manual.  Although there is no manual for the sensor, there is a feature that can be easily judged by looking at the meter terminal mark of the meter and marking part of each wiring. Conventional sensor terminals have a problem that a separate inspection work is necessary to understand the function of the wiring of the sensor terminals even though there is a manual on the meter terminals of the meter.
On the other hand, since the present invention can be compared with the manual of the meter simply by looking at the marking portion of the standard terminal block, it is not required to inspect a separate sensor terminal.






Characteristics of connection  If the characteristics of the wiring that forms the terminal block and the characteristics of the meter terminal of the meter can not be understood, there is a problem that the connection can not be made.  There is a feature that the meter terminal of the meter and the indication part of each wiring of the standard terminal block are checked and can connect easily to the non-specialist. Conventional sensor terminal blocks have different marking methods even if they have no markings, which makes it difficult or impossible to connect with the meter.
On the other hand, the present invention is characterized in that it can be easily determined even when the meter or sensor is changed by easily judging the standardized marking portion of the standard terminal block.





Color characteristics of wiring  There is a problem in the color of wiring every time the sensor is manufactured.  The color of the wiring connected to each electrode and function of the water quality sensor is uniform, and the marking is formed to uniformize wiring connected to the electrode. Conventional sensor terminals have a problem that it is difficult to connect with the meter due to the possibility of confusion due to the different wiring color.
On the other hand, according to the present invention, even if the color of the wiring is different, the characteristic of the wiring can be easily grasped through the marking part, and there is no problem in connection with the meter due to the wiring color change.







Display characteristics of wiring  There is a problem that it is difficult to distinguish the wiring connected to the sensor by the color of symbols, numerals and wiring itself.  A mark formed on the wiring is clearly distinguished by indicating the corresponding function among G, A, R, K, T1, T1, T2, T2, E, Conventional sensor terminals are difficult to identify and compare wiring characteristics when they are changed to other company's products by using various display methods according to characteristics of the manufacturer.
On the other hand, according to the present invention, a common and standardized indication is given to the mark portion of the standard terminal block according to the characteristic, so that even if the meter is changed, there is no problem in connection.






Characteristics of faults or measured values  If the terminal of the sensor and the meter terminal of the meter are not connected to each other, there is a problem that the water quality sensor is damaged or the measured value is not measured accurately.  By referring to the standardized marking section, it is possible to prevent the damage of the water quality sensor and obtain accurate measurement value by connecting it to the terminal of the sensor and the meter terminal of the meter according to the characteristics. If the sensor terminal is connected to the meter due to color confusion, there is a problem such as sensor malfunction, malfunction and meter error.
On the other hand, the present invention is characterized in that failure or error of the sensor or the meter does not occur by properly connecting the terminal with the indication of the meter terminal through the marking portion of the standard terminal block.

That is, the cable terminal block of the water quality measuring sensor according to the prior art produces a product without adopting a method of connecting the water quality measuring sensor and the cable of each manufacturer in an integrated and uniform manner, and the water quality sensor is treated as a consumable This makes it possible for the user to connect the cable of the water quality sensor and the meter terminal of the meter. In this case, the mark on the meter terminal is not identical to the terminal wiring of the cable. Even if the meter manual is checked, There is a problem in that it is not possible to connect to the meter for measurement because the wiring characteristic of the sensor is not known and it is inconvenient to separately check which electrode of the water quality sensor is connected to which electrode of the sensor by using the inspection device, If you are replacing the meter, If the meter and the display of the terminal and not the connection for connecting to different from each other incorrectly there is a problem it does not indicate a failure of the sensor and a precise measure.

On the other hand, according to the present invention, in the process of directly manufacturing the water quality measurement sensor, the wirings connected to the respective electrodes of the water quality sensor are standardized and the markers 30 are formed in the wirings, It is easy to connect the terminals of the water quality sensor easily by viewing the meter manual and knowing the characteristics of the meter terminal when the display displayed on the meter terminal of the meter is judged by viewing or it is different from the display of the meter terminal. It is possible to connect easily and to prevent the occurrence of failure or measurement error of the water quality measurement sensor.

That is, the meter terminal 201 of the meter 200 shown in FIG. 25 is indicated by a number for identification, and the cable terminal block of the water quality sensor according to the related art is connected to the meter terminal 201 It is impossible to know the information of the sensor wiring even if the manual of the meter 200 is referenced. Therefore, a verification method for each wiring is necessarily required. On the other hand, the present invention is characterized in that the user of the meter 200 recognizes the characteristics represented by the meter terminals 201 and compares the information of the wirings displayed on the marking unit 30, have.

In addition, when a conventional cable company discontinues a conventional cable and a cable of a new product is produced, the color and the number of wires of the wiring are changed, and when the electrode is connected to each electrode or sensor of the water quality sensor, the color of the wiring may be changed. There is a problem that it is necessary to newly recognize the characteristic and newly inform the user of the changed wiring information. On the other hand, the present invention shows the characteristic of the electrode or the sensor connected to the wiring in the marking part 30 regardless of the color of the wiring There is a characteristic that confusion does not occur.
