The installation positions of the second inlet and the second outlet can be set according to specific situations, for example, the position of the second inlet is higher than that of the second outlet, so that water inlet and water outlet are facilitated.
In some embodiments, the second inlet is disposed at the top of the test chamber 120, facilitating direct connection of the direct lines, simplifying the line setup.
In some embodiments, the second outlet is mounted at a position below the mounting position of the low level sensor 122 along the height of the test chamber 120, thereby ensuring that the lowest liquid level in the test chamber 120 can be below or up to the position of the low level sensor 122 in the event that the test chamber 120 is drained.
In some embodiments, the second inlet is mounted near the bottom of the test chamber 120, so that the liquid level in the test chamber 120 is gradually raised in an overflow manner, and the influence of liquid level fluctuation during liquid feeding on the test result is reduced.
The installation position of the second inlet is higher than that of the second outlet, so that the self gravity of the liquid is utilized as much as possible, and the energy is saved.
The first valve body 140 and the second valve body 150 may be valve bodies for controlling fluid flow, such as solenoid valves, drain valves, etc., as known in the art.

Further, a partition 123 is disposed in the test chamber 120, and the partition 123 separates the test chamber 120 from the liquid inlet chamber and the test chamber along the length direction of the test chamber 120; the partition 123 extends along the height direction of the test chamber 120, one end of the partition 123 is connected with the top of the test chamber 120, and the other end of the partition 123 has a gap with the bottom of the test chamber 120, so that the liquid inlet chamber is communicated with the bottom of the test chamber; the second inlet is located in the liquid inlet chamber, and the high liquid level sensor 121 and the low liquid level sensor 122 are located in the test chamber.
In this embodiment, by disposing the partition 123 in the test chamber 120, the inside of the test chamber 120 is partitioned into the liquid inlet chamber and the test chamber, and the liquid inlet chamber is communicated with the bottom of the test chamber, and the second inlet is located in the liquid inlet chamber, so that when liquid flows into the liquid inlet chamber from the second inlet, the liquid level in the test chamber is gradually raised in an overflow manner, and the influence of the liquid level fluctuation during liquid inlet on the test result is further reduced.
Further, a filtering buffer device 124 is arranged in the liquid inlet chamber; the inlet chamber and the test chamber communicate through a filter buffer 124.
After entering from the second inlet, the liquid flow is buffered and decelerated by the filtering and buffering device 124 and then flows into the testing chamber, so that the influence of liquid level fluctuation in the testing chamber on the testing result is avoided.
The filter buffer 124 may be made of a filter material such as a filter sponge, a filter felt, etc., as is known in the art.
Further, as shown in fig. 2, the sensor testing apparatus further includes: the data management unit is used for being connected with the sensor 160 to be tested, is connected with the control unit and is used for generating a test report.
In a specific embodiment, after the sensor 160 to be tested (e.g., a float sensor) is installed, the start test button is clicked, at which point the control unit opens the first valve body 140.
In the case that the liquid surface in the test chamber 120 contacts the sensors 160 to be tested, the control unit counts once, if a plurality of sensors 160 to be tested are provided, the control unit records the action of each sensor 160 to be tested, respectively, and simultaneously, the control unit records the cycle period and stores the data in the data management unit.
When the liquid level in the test chamber 120 contacts the high liquid level sensor 121, the control unit opens the second valve body 150 and simultaneously opens the pump body 130, and discharges the liquid level in the test chamber 120 to the installation position of the low liquid level sensor 122, and at this time closes the second valve body 150 and the pump body 130.
According to this logic, the control system is cycled. After a certain time, the sensor testing device has run n cycles, clicking the stop test button.
At this time, assuming that the number of actions of the collected sensor 160 to be measured is D1, D2, D3 … Dn, the control unit stores the collected data in the data management unit.
Since each sensor under test 160 tested is activated once per cycle, d1=d2= … =dn=n at this time.
When dn+.n, for example Dn > n or Dn < n, it is determined that the sensor 160 to be tested is faulty, and the operator is reminded to detect again.
After the floating ball sensor is tested, the produced test report is exemplified as follows:
according to the sensor testing device provided by the utility model, in the first aspect, the liquid is circulated in the sensor testing device by using the liquid storage chamber 110, so that the waste of water resources is reduced; in the second aspect, a partition 123 and a filtering buffer 124 are provided inside the test chamber 120 to prevent fluctuation of the liquid level inside the test chamber, resulting in inaccuracy; in the third aspect, a plurality of sensors 160 to be tested can be tested at the same time, improving the working efficiency.
Finally, it should be noted that: the above embodiments are only for illustrating the technical solution of the present utility model, and are not limiting; although the utility model has been described in detail with reference to the foregoing embodiments, it will be understood by those of ordinary skill in the art that: the technical scheme described in the foregoing embodiments can be modified or some technical features thereof can be replaced by equivalents; such modifications and substitutions do not depart from the spirit and scope of the technical solutions of the embodiments of the present utility model.
