Abstract
The utility model relates to a corrosion-resistant double liquid level sensor, which comprises a guide bar and a mounting seat welded at the upper end of the guide bar. The mounting seat is connected with a DIN (deutsche industrie norm) socket in a threaded manner, a DIN plug is arranged on the upper portion of the DIN socket, a float seat and a pressure ring are sleeved on the upper portion of the guide bar, a limit ring is arranged at the bottom of the guide bar, an upper limit reed switch is arranged on the inner upper portion of the guide bar, a lower limit reed switch is arranged on the inner lower portion of the guide bar, the upper limit reed switch and the lower limit reed switch are connected with binding posts of the mounting seat respectively through leads, a permanent magnet ring is arranged between the float seat and the pressure ring, and a float is mounted on the float seat. The corrosion-resistant double liquid level sensor is durable, simple in structure, reliable in performance, low in cost, capable of being used for detecting level of strong base, strong acid, oils and oily liquids, fine in visuality and higher in adaptability.
Description
Technical field
The utility model relates to a kind of liquid level sensor that is used for Level Detection, relates in particular to a kind of corrosion-resistant biliquid level sensor.
Background technology
Liquid level sensor is the electron device that is used for the tracer liquid liquid level.Liquid level sensor is divided into two types, and one type is contact, comprises single flange static pressure and two flange differential pressure liquid level sensors; The float-ball type liquid level sensor, magnetic level sensor, throw-in type liquid level sensor; Electronic inner float ball liquid level sensor, electronic float level sensor, capacitance level transducer; Magnetostrictive liquid level sensor is waitd upon clothes liquid level sensor etc.; Second type is contactless, is divided into ultrasonic liquid level sensor, radar level sensor etc.Common on the market float-ball type liquid level sensor is processed by stainless steel material at present, comprises lead, guide rod, ball float, permanent-magnetic clamp in the ball float and the tongue tube in the guide rod.This kind sensor is cheap, but weak point is: the damaged situation of lead appears in lead unprotect measure easily.When detecting,, the sticking couplet of ball float and guide rod can occur, cause sensor failure because the stainless steel oil-wet behavior works long hours for the liquid level of oil product liquid level and oily liq.
The utility model content
The purpose of the utility model provides a kind of corrosion-resistant biliquid level sensor, to overcome the deficiency of the above-mentioned aspect of prior art.
The purpose of the utility model is to realize through following technical scheme:
A kind of corrosion-resistant biliquid level sensor comprises guide rod and mount pad, and the upper end of said guide rod is welded with mount pad, and mount pad and DIN socket are through being threaded, and the top of DIN socket is provided with DIN connector; Said guide rod top is installed with float seat and pressure ring; The bottom of guide rod is provided with spacing ring; The guide rod internal upper part is provided with the upper limit tongue tube, and the bottom is provided with the lower limit tongue tube in the guide rod, and the upper limit tongue tube is connected with the binding post of mount pad through lead-in wire respectively with the lower limit tongue tube; Be provided with permanent-magnetic clamp between said float seat and the pressure ring, on the float seat float be housed.
The beneficial effect of the utility model is: durable in use, simple in structure, and dependable performance, cheap; Can be used to detect highly basic, strong acid liquid level, oil product and oily liq liquid level; Visual good, have stronger adaptability.
Description of drawings
According to accompanying drawing the utility model is done further explain below.
Fig. 1 is the one-piece construction synoptic diagram of the described corrosion-resistant biliquid level sensor of the utility model embodiment.
Among the figure:
1, guide rod; 2, float; 3, spacing ring; 401, lower limit tongue tube; 402, upper limit tongue tube; 5, lead-in wire; 6, float seat; 7, pressure ring; 8, mount pad; 9, DIN socket; 10, DIN connector; 11, permanent-magnetic clamp.
Embodiment
As shown in Figure 1; The described a kind of corrosion-resistant biliquid level sensor of the utility model embodiment comprises guide rod 1 and mount pad 8, and the upper end of said guide rod 1 is welded with mount pad 8; Mount pad 8 and DIN socket 9 are through being threaded, and the top of DIN socket 9 is provided with DIN connector 10; Said guide rod 1 top is installed with float seat 6 and pressure ring 7; The bottom of guide rod 1 is provided with spacing ring 3; Guide rod 1 internal upper part is provided with upper limit tongue tube 402, and the bottom is provided with lower limit tongue tube 401 in the guide rod 1, and upper limit tongue tube 402 and the dried spring 401 of lower limit 5 are connected with the binding post of mount pad 8 through going between respectively; Be provided with permanent-magnetic clamp 11 between said float seat 6 and the pressure ring 7, float 2 is housed on the float seat 6.
Float 2 adopts PP or PC material, and float seat 6 and pressure ring 7 adopt the PVC material, and said two tongue tubes are fixed through heat-shrink tube respectively.
During concrete the use, prescribe a time limit when liquid level is lower than down, lower limit tongue tube 401 is in the lead-in wire junction G2 output signal under the permanent magnetic action, when liquid level constantly rises, surpasses down in limited time, and lower limit tongue tube 401 resets, and the G2 no signal is exported; Go up in limited time when liquid level arrival, the lead-in wire junction G1 that upper limit tongue tube 402 is under the permanent magnetic action exports signal, and liquid level drops to be lower than to go up prescribes a time limit, and upper limit tongue tube 402 resets, the G1 no signal.
The utility model is not limited to above-mentioned preferred forms; Anyone can draw other various forms of products under the enlightenment of the utility model; No matter but on its shape or structure, do any variation; Every have identical with a application or akin technical scheme, all drops within the protection domain of the utility model.
