Abstract
The utility model discloses a pressure transmitter. The pressure transmitter comprises a pressure measuring film box, wherein the pressure measuring film box is internally provided with a circuit board and a signal connection wire, the circuit board is fixedly arranged in a chamber of the pressure measuring film box, one end of the signal connection wire is fixedly connected with the circuit board, and the other end of the signal connection wire extends out of the pressure measuring film box. The pressure transmitter is characterized in that: the chamber of the pressure measuring film box is internally filled by waterproof sealing material, the circuit board and the signal connection wire are wrapped by the waterproof sealing material. During use of the pressure transmitter, the waterproof sealing material can prevent water from entering the chamber of the pressure measuring film box, so damage to the circuit board is avoided, and normal operation of signal transmission is guaranteed.
Description
Technical field
The utility model belongs to the surveying instrument technical field, specifically, relates to a kind of pressure unit.
Background technology
Pressure unit mainly is made up of load cell, metering circuit and process web member three parts.In the pressure unit course of work, automatically controlled is its important part, when automatically controlled defectiveness, influences the operate as normal of this pressure unit, for guarantee that signal transmits operate as normal, thereby particularly important for the protection of circuit board in the pressure measurement bellows.
The prior art shortcoming: existing pressure unit in use, liquid such as water enter in the pressure measurement break-in easily, destroy circuit board, cause circuit board damage.
Summary of the invention
For solving above technical matters, the purpose of this utility model be to provide a kind of can the holding circuit plate, prevent the pressure unit of circuit board damage.
The utility model purpose is achieved in that
A kind of pressure unit, comprise the pressure measurement bellows, be provided with circuit board and signal connecting line in the described pressure measurement bellows, described circuit board is fixedly installed in the chamber of described pressure measurement bellows, described signal connecting line one end is fixedlyed connected with described circuit board, the other end stretches out described pressure measurement bellows, and its key is: be filled with waterproof and sealing material in the chamber of described pressure measurement bellows, described waterproof and sealing material surrounds circuit board and signal connecting line.Adopt said structure, described waterproof and sealing material can be prevented liquid substance damage circuit boards such as sealing.
Above-mentioned waterproof and sealing material is polyurethane material.Adopt said structure, have advantages such as seamless, efficient insulation, waterproof, protection against the tide after filling described polyurethane material, further protected circuit board, guarantee the operate as normal that signal transmits.
Beneficial effect:
The utility model is pressure unit, and in use, waterproof and sealing material can prevent that liquid such as sealing enters in the chamber of pressure measurement bellows, and circuit board is caused damage, has guaranteed the operate as normal that signal transmits.
