Preferably, the end away from described shell of described body is provided with a junction, and described connecting portion is provided with one first ring groove, is used for and a pipeline clamping.The connected mode of this clamping is simple, convenient, rapidly this transmitter of installation and removal on pipeline.
Preferably, also be provided with one second ring groove on described connecting portion, be embedded with one first O-ring seal in described the second ring groove.This first O-ring seal can carry out effective sealing to being connected between this transmitter and pipeline.
Preferably, the end away from described body of described shell is provided with a plug connector, is used for being connected with a control terminal.This plug connector replaces traditional aerial plug-in unit, uses convenient.
Preferably, described plug connector is provided with four contact pins, and described contact pin penetrates described shell, and be located at described shell in circuit board on the welding of corresponding jack.
Preferably, be covered with a packing ring on described sensor element, the edge of described packing ring is provided with through hole, and the wire that is connected with described compensating plate passes from described through hole, and is connected to described circuit board.
Preferably, be covered with a press strip on described packing ring.Compress packing ring, sensor element and second O-ring seal of its below by press strip, guarantee good sealing effectiveness.
Preferably, the material of described body and shell is plastics.Traditional transmitter generally adopts body and the shell of metal material, and this transmitter adopts plastics, more saves production cost.
Preferably, described casing is located on described body, and with described body clamping.The mode that this clamping connects is convenient, easy to operate.
Preferably, also be provided with one second O-ring seal in described body, described the second O-ring seal is positioned at the bottom of described hollow bulb.This second O-ring seal can effectively guarantee the sealing effectiveness of this transmitter inside, prevents from treating that fluid measured is bled into this transmitter by sensor element inner, and causes the damage of transmitter.
Positive progressive effect of the present utility model is: floor heating that the utility model provides is little, simple in structure with the transmitter volume, can Fast Installation and dismounting, and production cost is low, also has good sealing effectiveness.
