Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model embodiment is described in detail.
As depicted in figs. 1 and 2, the utility model embodiment provides a kind of horizontal detection sensor, comprise tank body 2 and circuit board 3, pressing plate 5, gland 6, float 9 and displacement transducer 10 are installed in described tank body 2, on the sidewall of described tank body 2, install and be provided with liquid level gauge 12; Wherein said circuit board 3 is arranged on described pressing plate 5, and pressing plate 5 is fixedly connected with described tank body 2 inwalls by card key 4; Gland 6 one end are fixedly connected with pressing plate 5, and the other end is fixedly installed sensor installation seat 7; Described float 9 is suspended on described sensor installation seat 7 belows, and displacement transducer 10 is fixedly connected with float 9.
Tank body 2 is divided into upper cavity and lower chamber by described sensor installation seat 7, and described circuit board 3, pressing plate 5 and gland 6 are positioned at described upper cavity, and described float 9 and displacement transducer 10 are positioned at described lower chamber. Wherein said sensor installation seat 7 one sides are provided with vent valve 8, in the time that transport stores, vent valve 8 can be shut, in case liquid is revealed; In the time of horizontal detection working sensor, vent valve 8 is opened, the liquid being communicated with is communicated with atmospheric pressure.
The liquid level that described tank body 2 bottoms are provided with for introducing horizontal indicator solution is communicated with interface 13. And the shell of tank body 2 uses stainless steel manufacture, airtight antispraying structure, service life is longer.
In addition, described horizontal detection sensor also comprises cable connector 11 and top cover 1, and wherein said cable connector 11 is arranged on the lateral wall of described tank body 2 and is connected with described circuit board 3, and described top cover 1 is connected with tank body 2 tops by screw.
