Abstract
The utility model relates to a differential pressure sensor and especially relates to an all-welded differential pressure sensor. The technical scheme is that: the all-welded differential pressure sensor comprises a sensor main body housing; the sensor main body housing is internally provided with an H connector, an isolation diaphragm, a differential pressure core sintering seat, an isolation diaphragm and an L connector. The upper portion of the sensor main body housing is provided with a connection ring, cables and an electric connector. The connection ring is internally provided with an insulation pressing ring, a lead wire switching board and a fixation board. The L connector and the isolation diaphragm are welded with the low-pressure end of the differential pressure core sintering seat; the H connector and the isolation diaphragm are welded with the high-pressure end of the differential pressure core sintering seat; and the L connector and the H connector are welded with the two ends of sensor main body housing. The beneficial effects are that: the differential pressure sensor is all-welded, small in volume, good in sealing effect, strong in bearing static pressure, strong in overload capacity, convenient to install and use, capable of accurately and reliably measuring the fluid medium which is compatible with stainless steel materials, and can be widely applied to occasions, which require pressure automatic detection and controlling, such as the food, pharmacy, oil and chemical engineering field.
Description
Technical field
The utility model relates to a kind of differential pressure pick-up, be particularly related to a kind of full welding differential pressure pick-up, be applied in industrial process detection and control system, the medium with 316L stainless steel material compatibility is detected, and the pressure signal recorded is converted to the differential pressure pick-up of electric signal.
Background technology
Along with industrial expansion, energy-conservation of consumption reduction, enhance productivity, reduce production costs, improving the quality of products is each enterprise's emphasis, the extensive application of pressure transducer makes technological transformation be achieved, but high to static pressure, volume requirement is little, the test of medium under rugged surroundings that be corrosive, most differential pressure pick-ups are helpless.Existing differential pressure pick-up is by O shape rubber seal rings for seal, can only test and stainless steel, the elastomeric material measurement of compatible medium simultaneously.
Summary of the invention
The purpose of this utility model is exactly in view of the foregoing defects the prior art has, provide a kind of full welding, good seal performance, volume little, can bear the full welding differential pressure pick-up of high static pressure, applicable tested media wide ranges.
Its technical scheme is: comprise the sensor main body shell, the built-in H joint of sensor main body shell, isolation diaphragm, differential pressure core body sintering seat, isolation diaphragm and L joint, sensor main body shell upper end is provided with abutment ring, winding displacement and electric connector, and insulation pressure ring, lead-in wire card extender and fixed head are set in abutment ring; The wherein low pressure end of L joint, isolation diaphragm and differential pressure core body sintering seat welding, the high-pressure side welding of H joint, isolation diaphragm and differential pressure core body sintering seat, the two ends welding of L joint, H joint and sensor main body shell.
Above-mentioned abutment ring is welded on the upper end of sensor main body shell, and insulation pressure ring, lead-in wire card extender, fixed head are assemblied in the inner chamber of abutment ring, in order to fixedly winding displacement, electric connector.
The beneficial effects of the utility model are: full welding, volume are little, good sealing effect, bear that static pressure is large, overload capacity is high, easy to install, the fluid media (medium) with the stainless steel material compatibility can be accurately measured reliably, food, pharmacy, oil, the chemical field occasion to the automatic Detection & Controling of pressure can be widely used in.
