Abstract
The utility model discloses a pressure sensor, including sensor housing and sensor lid, sensor housing passes through threaded connection with the sensor lid, sensor housing embeds has sealing member and circuit board, be provided with MCU and sensor chip on the circuit board. The utility model discloses an effective effect: this designs simple structure, and is with low costs, the intellectuality, can realize highly reliable detection and long life, but the wide application detects in fluid pressure.
Description
Technical field
The utility model belongs to pressure sensor design field, particularly a kind of pressure transducer.
Background technology
Pressure transducer is a kind of sensor the most conventional in industrial practice, be the device based on physical construction, with elastic deformation indicated pressure, be widely used in various industrial automatic control environment, such as hydraulic pressure or pneumatic system etc., for the pressure of measuring system region of interest.
The pressure sensor structure of current common use is simple, function singleness, when in the cited systems such as valve switch or pumping plant keying during pressure instantaneous variation, the instantaneous pressure of appearance tends to exceed the maximum rated pressure of pressure transducer internal induction diaphragm, is that this pressure transducer is destroyed.
Utility model content
Based on above problem, the purpose of this utility model is to provide a kind of high precision, fast response, intelligentized pressure transducer.
A kind of pressure transducer, comprise sensor housing and sensor lid, described sensor housing and sensor lid are threaded connection, described sensor housing is built-in with seal and circuit board, described seal is O-ring seal, described O-ring seal external diameter is consistent with sensor housing internal diameter, described circuit board is provided with MCU and two sensor chip, and described sensor chip is MEMS element.
Effective effect of the present utility model: this project organization is simple, and cost is low, intelligent; Highly reliable detection and long life can be realized; Hydrodynamic pressure can be widely used in detect.
Accompanying drawing explanation
Fig. 1 is the exploded perspective view of a kind of pressure transducer of the utility model;
Fig. 2 is the structural representation of a kind of pressure transducer of the utility model.
Number in the figure is described as follows: 1-sensor housing, 2-sensor lid, 3-seal, 4-circuit board.
Embodiment
The technical solution of the utility model is further illustrated by embodiment below in conjunction with accompanying drawing.
Shown in Fig. 1 and Fig. 2, for the structural representation of a kind of pressure transducer of the utility model, comprise sensor housing 1 and sensor lid 2, sensor housing 1 and sensor lid 2 are threaded connection, and sensor housing 1 is built-in with seal 3 and circuit board 4, circuit board 4 is provided with MCU and sensor chip, surface coating silica gel is used for isolation and sealing, sensor chip is two, and seal 3 is O-ring seal, and O-ring seal external diameter is consistent with sensor housing 1 internal diameter.
In sensor housing 1, first put into seal 3, then put into circuit board 4, then screw in sensor housing 1 with sensor lid 2, compress circuit board 4; Circuit board 4 is provided with MCU and two pressure sensing chip, for subsequent use to do, highly reliable detection and long life can be realized.
Pressure sensor chip is MEMS element, is to utilize microelectronics and the produced novel sensor of micromachining technology.Compared with traditional pressure transducer, it has, and volume is little, lightweight, cost is low, low in energy consumption, reliability high.Meanwhile, make it can complete the irrealizable function of some traditional mechanical pressure sensor in the characteristic dimension of micron dimension, can improve accuracy and the response speed of system testing to a great extent.The utility model structure is simple, and cost is low, intelligent; The pressure detection that high precision is highly reliable can be realized; Hydrodynamic pressure can be widely used in detect.
Embodiment recited above is only be described preferred implementation of the present utility model; not scope of the present utility model is limited; under the prerequisite not departing from the utility model design spirit; the various distortion that the common engineering technical personnel in this area make the technical solution of the utility model and improvement, all should fall in protection domain that claims of the present utility model determine.
