Description

Bucket formula level sensing apparatus

The utility model relates to liquid level sensor, is specially a barrel formula level sensing apparatus.

Present liquid level sensor is that float moves up and down along with the variation of liquid level, drives fork and rotates, and slide plate is because of sliding on slide-changing resistor with the fork one, thereby output resistance is changed, and passes through the signal processing and amplifying, indicates liquid level.Owing to the significantly vibrations of liquid level along with container change greatly, slide on slide-changing resistor thereby make float drive slide plate, cause the variation of output resistance also very big, pointing accuracy is inaccurate, not the liquid level of energy measurement small container.

The purpose of this utility model be to provide a kind of simple in structure, with low cost, can measure small container, bucket formula level sensing apparatus that precision is high.

The purpose of this utility model is achieved in that it is by mounting disc (2); resistance R (3); slide-changing resistor silk (4); float (5); slide plate (6); protection tube (7); support bar (8); carriage (9) constitutes; turnover oilhole (10) is arranged at the top at protection tube (7); on the bottom of protection tube (7), have turnover oilhole (10); the bottom of support bar (8) and carriage (9) are connected and fixed on the bottom of protection tube (7); the top of support bar (8) is connected with mounting disc (2); float (5) is enclosed within on the support bar (8) and can slides up and down; slide-changing resistor silk (4) one ends are fixed on the carriage (9); the other end is connected with binding post (1); at close binding post (1) one end, the two ends of resistance R (3) are connected with slide-changing resistor silk (4) respectively.

Advantage of the present utility model is: simple in structure, with low cost, measure accurately, bulk container, small container all be suitable for, and be safe and reliable.

Fig. 1 is the utility model structural principle synoptic diagram.

Fig. 2 is the utility model pad principle schematic.

Below in conjunction with accompanying drawing in detail the utility model most preferred embodiment is described in detail: it is by mounting disc (2); resistance R (3); slide-changing resistor silk (4); float (5); slide plate (6); protection tube (7); support bar (8); carriage (9) constitutes; turnover oilhole (10) is arranged at the top at protection tube (7); on the bottom of protection tube (7), have turnover oilhole (10); the bottom of support bar (8) and carriage (9) are connected and fixed on the bottom of protection tube (7); the top of support bar (8) is connected with mounting disc (2); float (5) is enclosed within on the support bar (8) and can slides up and down; slide-changing resistor silk (4) one ends are fixed on the carriage (9); the other end is connected with binding post (1); at close binding post (1) one end, the two ends of resistance R (3) are connected with slide-changing resistor silk (4) respectively.In what size variation of oil mass, float 5 slides up and down at support bar 8 along with fluctuating of pasta, float 5 sliding up and down on slide-changing resistor silk 4, and then the size of Bian Huaing is exported to electric signal and amplifies and show by binding post 1.
