Abstract
The utility model discloses a pressure transmitter which comprises a chip body assembling body; the chip body assembling body is internally provided with a ceramic sensor; the lower end of the ceramic sensor is provided with an 'O'-shaped seal ring which is arranged in a seal groove in the chip body assembling body; the upper part of the ceramic sensor is provided with a clamping and fixing device comprising a pressing ring and a clamping spring which are adaptive mutually; the upper end of the ceramic sensor is provided with a circuit board; the upper end of the circuit boad is provided with a socket fixing element; the upper end of the socket fixing element is provided with a PACKARD socket. According to the utility model, the structure that the 'O'-shaped seal ring is installed in the seal groove, then a purple copper pressing ring and a clamping spring combination are utilized for compressing the seal ceramic sensor is adopted. A processing element and two standard elements are added to complete the compression seal function, the processing cost is lowered, and meanwhile the seal accuracy is improved. A convex edge arranged at the edge of the socket fixing element increases the reliability of electric appliance connection, and the socket is prevented from rotating as the temperature variation after edge wrapping.
Description
Technical field
The utility model belongs to pressure sensor technique field, specifically a kind of pressure unit.
Background technology
Pressure unit mainly is comprised of load cell (also referred to as pressure transducer), metering circuit and process web member three parts.The physical pressure parameters such as the gas that it can be experienced load cell, liquid are transformed into the electric signal of standard, and the secondary instruments such as indicator alarm, registering instrument, regulator are measured to supply with, indication and procedure regulation.Present pressure unit is mainly to adopt high-performance ceramic diaphragm and substrate, the thick film ceramic pressure drag type pressure transmitter that thick film technology (TFT) and surperficial little package technique (SMT) process; Microprocessor is processed core component as signal, realize the conditioning (filtering, amplification, A/D conversion etc.) of linear operation, correction, temperature compensation, fault diagnosis and communication function, measuring-signal, Wheatstone bridge detected pressures signal and the electronic unit through being connected compensate, amplification and conversion process, and software program solves the thick film ceramic pressure drag type pressure transmitter of nonlinear compensation and issues of temperature compensation; Sensor core is by two pressing plates and " O " type rubber ring and bolt seal and the sealing means that links with hydraulic system; Plug adopts the electrical connecting patterns such as Hirschmann socket or Packard.Pressure unit production at present mainly adopts the diffuse si sensor to add the debugging of analog amplify circuit plate, and sealing means adopts the radial seal of screw thread hold-down ring.But the housing main body that this sealing means need to be processed is three, core body assembly, tube core hold-down ring, sleeve pipe.Processing cost is larger, and sealing effectiveness is poor.
The utility model content
Technical problem to be solved in the utility model is to provide a kind of cost pressure unit low, simple in structure, easy to use for the shortcoming of prior art.
Adopt following technical scheme for solving technical matters of the present utility model:
A kind of pressure unit, comprise the core body assembly, in described core body assembly, ceramic sensor element is set, the lower end of described ceramic sensor element arranges " O " RunddichtringO, described " O " RunddichtringO be arranged in core body assembly body seal groove in, the top of described ceramic sensor element arranges clamping fastener, described clamping fastener comprises adaptive pressure ring and jump ring mutually, the upper end of described ceramic sensor element arranges wiring board, the upper end of described wiring board arranges socket retainer, and the upper end of described socket retainer arranges the PACKARD socket.
Described " O " RunddichtringO is nitrile rubber " O " RunddichtringO.
Described pressure ring is the red copper pressure ring.
Described socket retainer edge arranges chimb, and the inboard draw-in groove that arranges of described chimb and core body assembly upper end is adaptive.
The utility model has adopted " O " RunddichtringO to be arranged in seal groove, then makes up the structure of press seal ceramic sensor element with red copper pressure ring, jump ring.This structure adds two standard components with a workpiece can complete the press seal function, has reduced processing cost, has improved simultaneously the precision of sealing.The chimb of socket retainer edge setting has increased the reliability that electrical equipment connects simultaneously, prevents that socket later on can be along with temperature variation is rotated at bound edge.

Embodiment
Below in conjunction with accompanying drawing, the utility model is described in further detail:
As shown in Figure 1, 2, 3, a kind of pressure unit, comprise core body assembly 1, core body assembly 1 body inner bottom part has seal groove, nitrile rubber " O " RunddichtringO 2 is arranged in seal groove, then ceramic sensor element 3 is installed, the top of ceramic sensor element 3 arranges clamping fastener 4, and clamping fastener 4 comprises adaptive red copper pressure ring and jump ring mutually.Adopt nitrile rubber " O " RunddichtringO 2, red copper pressure ring, jump ring combination press seal ceramic sensor element 3, reduced processing cost, improved simultaneously the precision of sealing.。The upper end of ceramic sensor element 3 arranges wiring board 5, the upper end socket retainer 6 of wiring board 5, and PACKARD socket 7 is installed in the upper end of socket retainer 6.Socket retainer 6 edges arrange chimb, and the inboard draw-in groove that arranges of chimb and core body assembly 1 upper end is adaptive, prevent PACKARD socket 7 distortion that cause due to high low temperature and rotate, and have increased the reliability that this electrical equipment connects.
