The material-level sensor consists of two closed sensor probes, an electronic module, damping rubber rings, a sensor shell and a sensor rear cover plate, wherein the closed sensor probes are installed in the sensor shell and connected with the electronic module by electronic lead wires, pouring sealant is filled between the closed sensor probes and the electronic module which is arranged on the sensor rear cover plate, the sensor rear cover plate is installed on the sensor shell, two independent sensor installation seats are arranged in the sensor shell and provided with the closed sensor probes, and the damping rubber rings are sheathed on the closed sensor probes. The closed ultrasonic material-level sensor is simple in structure, and can be used in the damp and dusty environments. As the two probes reduce blind area, the closed ultrasonic material-level sensor can be used for the measurement of less space, and avoid crosstalk between the two probes.
Description
Technical field
The utility model closed ultrasonic level sensor belongs to sensor field.Particularly relate to a kind of ultrasonic sensor.
Background technology
Level meter at present commonly used has contact and contactless two kinds, and wherein contact comprises condenser type, float-ball type, Weight type, static pressure type or the like, contactless laser type, electromagnetic type and the ultrasonic type of comprising.The characteristics of contact type measurement are to measure reliably, but owing to instrument in use must contact with tested material, so measuring accuracy can be received the influence of material.At some sanitary condition or material cleanliness factor there are the occasion of requirement, also should not adopt the contact level meter.Non-contact measurement does not contact with material, does not have mechanical running gear, but because laser type and electromagnetic type cost are higher, so ultrasonic material level meter is more and more used.The ultrasonic level sensor is the core component of ultrasonic material level meter, and it surveys distance between object (solid or liquid) surface and the sensor emission face by transmitting and receiving of ultrasonic signal, and the signal of handling passed to controls and display module.Closed ultrasound wave material sensor has been owing to adopted full-closed structure, avoided contacting of electronic circuit part and external environment, therefore can be used for humidity or the environment of dust is arranged.Common closed ultrasound wave level sensor is to adopt a ultrasonic probe at present, owing to can't eliminate the influence of probe remained shock, therefore near sensor probe, there is blind area in a big way, causes the type sensor to use in the measurement that is used for closer distance or in less space.What the two probe ultrasonic sensors that use at present used is open probe, this type of ultrasonic sensor can be measured nearer distance, but can't be applied to humidity and the environment that dust is arranged, can only be used for the environment of clean dried, can't be used for material level or level gauging.
The utility model content
The purpose of this utility model is to avoid the deficiencies in the prior art part, provides a kind of blind area little, can be used for the closed ultrasonic level sensor of close-in measurement.
The purpose of this utility model reaches by following measure, closed ultrasonic level sensor comprises by enclosed sensors pops one's head in, electronic module, the damping rubber cushion rubber, sensor outer housing and sensor back shroud are formed, the enclosed sensors probe is installed in the sensor outer housing, be connected by electric leads between enclosed sensors probe and the electronic module, fill casting glue between enclosed sensors probe and the electronic module, electronic module is arranged on the sensor back shroud, the sensor back shroud is installed on the sensor outer housing, in sensor outer housing, be provided with two independently sensor mount pads, independently on the sensor mount pad enclosed sensors probe is installed at two, the damping rubber snare is on the enclosed sensors probe.
Be connected sealing with glue between damping rubber cushion rubber of the present utility model and the sensor outer housing, the distance between two sensor probes is 5-15mm, and two enclosed sensors probe mounting angles differ 90 degree.
The utility model adopts two probe modes, two enclosed sensors probes, and an enclosed sensors probe sends ultrasonic pulse signal, and another enclosed sensors probe receives the ultrasonic signal that reflects.Ultrasound-driven circuit and signal receiving circuit have been comprised on the electronic module, microprocessor control Driver Circuit in the circuit, send the electric signal that meets ultrasonic transducer, electric signal is applied on the enclosed sensors probe, makes the enclosed sensors probe produce ultrasound wave and propagates in air.When ultrasound wave ran into barrier, according to the characteristic of sound wave, sound wave can be reflected.When reflective sound wave is got back to reception enclosed sensors probe, receive the enclosed sensors probe and can convert ultrasonic/sonic wave to electric signal, electric signal partly amplifies and processing through signal at receiving circuit, calculates through microprocessor, at last by signal wire output result again.Distance between two enclosed sensors probe is 5-15mm, the generation that cavity between two probes and damping rubber cushion rubber greatly reduce " cross-talk " phenomenon.In addition, closed structure of the present utility model can be stopped objects such as water, dirt and enter sensor internal, makes product can be applicable to humidity and the environment that dust is arranged.
The utility model is simple in structure, can be used for moist and the dust environment, two probes have reduced the blind area, can be used for the measurement in less space, has avoided the crosstalk problem between two probes.
