The utility model is characterized in that a housing is sheathed with a high and low pressure guiding nozzle. An internal cavity constituted by connecting the housing and a front cover and a rear cover is provided with a temperature measuring element, a low pressure cavity end cap, a pressure difference electric resistance strain gauge, a pressure difference elastic membrane, a pressure difference E-shaped block, a high pressure cavity end cap, a high pressure elastic membrane, a static pressure electric resistance strain gauge, a circuit board, a display, and a connecting terminal board. The utility model has the advantages of simple structure, small size, low cost, many functions, and excellent performance, and can simultaneously measure the static pressure parameter, the pressure difference parameter and the temperature parameter.
Description
The utility model relates to a kind of measuring head device, the particularly a kind of transmitter that can measure static pressure, pressure reduction, temperature simultaneously.
Existing transmitter can only be measured a kind of parameter on a measurement point usually, function singleness, if measure static pressure, pressure reduction, temperature simultaneously, just must be simultaneously with three transmitters, so just caused installing that the transmitter position must enlarge and the increase of expense cost, and manipulated inconvenience, difficulty is installed.
The purpose of the utility model aim to provide a kind of simple in structure, reasonable in design, volume is little, cost is low, can carry out static pressure simultaneously, pressure reduction, temperature parameter is measured, function is many transmitter.
Technical solution of the present utility model is: be set with the high pressure impulse and chew with the low pressure impulse and chew on housing, in the inner chamber that housing and front and rear covers connect to form, temperature element is installed, the low-pressure cavity end cap, the pressure reduction resistance strain gage, the pressure reduction flexible sheet, pressure reduction E shape piece, the high pressure chest end cap, the high-pressure elastomeric diaphragm, the static pressure resistance strain gage, circuit board, display, terminal board, the high-pressure elastomeric diaphragm, the pressure reduction flexible sheet, the low-pressure cavity end cap is arranged in order, the sensing assembly bolted is also used together in the upper end, the high-pressure elastomeric diaphragm, the pressure reduction flexible sheet, be separately installed with the static pressure resistance strain gage on the low-pressure cavity end cap, the pressure reduction resistance strain gage, temperature element, circuit board, display and terminal board are fixed on above-mentioned sensing assembly both sides respectively, high, the low pressure impulse is chewed the upper end and is connected and fixed height respectively, low chamber end cap, the lower end connects height respectively, the low pressure tracting pressuring hole.
The utility model is compared with prior art, can measure static pressure, pressure reduction, these comprehensive parameters of temperature simultaneously, function is many, changed the function singleness situation that the past can only measure a kind of parameter at measurement point, the utility model is simple in structure, reasonable in design, volume is little, cost is low, fitting operation is convenient, reliable operation, function admirable.
