Product Description Product DescriptionCYX 19/32 series oil injection core pressure sensor adopts the internationally advanced high stability and high precision silicon pressure chip, and adopts the sintering seat with stress optimization design, which is produced by the processes of chip mounting, gold wire bonding, diaphragm welding, high vacuum oil injection, pressure cycle stress relief, high temperature aging, temperature compensation, etc. With more than 30 years of development, production experience and technological innovation, the products have excellent stability and performance, and are widely recognized by users.1.1General CYX19 pressure sensorThe shape, assembly size and sealing method of the general CYX19 are consistent with the same kind of international mainstream products, which gives CYX19 good interchangeability. It is widely used in the pressure detection of the medium compatible with SS316L, NBR 1.2CYX19 pressure sensor with chloride ion corrosion resistanceCYX19Ti pressure sensor shares the same shape, assembly dimension and sealing form as the general CYX19. Structure uses titanium alloy: TC4 with high strength and good corrosion resistance is selected as the shell, TA1 is selected as the diaphragm, which is more suitable for the medium with strong corrosion of chloride ions such as seawater. Working in humid atmosphere and sea water medium, its corrosion resistance is far superior to that of stainless steel products. It has strong resistance to pitting, acid and stress corrosion, and excellent corrosion resistance to organic substances of alkali / chloride /chlorine, nitric acid, sulfuric acid, etc. Measurement range is -100kPa ~ 0 ~ 10kPa…100MPa.1.3Negative pressure measuring CYX series (model + Y)Through the production of special negative pressure technology, the general pressure sensor and other models can reliably detect pressure below atmospheric pressure, and the range is between -100kPa ~ 3MPa.Featuresmeasurement range: 0kPa ~ 10kPa…100MPa3 pressure forms: gauge pressure (G), absolute pressure (A), seal gauge pressure (S)constant current / voltage supplyisolated structure, suitable for multiple fluid mediaΦ 19mm standard OEM pressure oil injection coreall 316L stainless steeltitanium structure optional, tantalum diaphragm customizedApplications1.industrial process control 2.liquid level measurement 3.gas and liquid pressure measurement 4.pressure detection and calibration instrument 5.pressure switch and hydraulic system 6. well monitoring7.refrigeration equipment and air conditioning system 8.fire Internet of thingsTechnical Index4.1Electrical performance power supply: ≤ 3.0ma; DC ≤ 10V DCelectrical connection: 0.2mm2 four color 100mm silicon rubber flexible wirecommon-mode voltage output: 50% of current type input (typical value), 40% of voltage type input (typical value)input impedance: 2.7kΩ ~ 5kΩoutput impedance: 3.0kΩ ~ 6kΩresponse time (10% - 90%): < 1msinsulation resistance: 500MΩ / 100V DCallowable overvoltage: 1.5 times of full scale4.2Structure performance diaphragm material: stainless steel 316L / titanium TA1 (CYX19Ti)shell material: stainless steel 316L / titanium TC4 (CYX19Ti)pressure lead-in tube material: stainless steel 316Lpin lead: gilded Kovarsealing ring: NBRnet weight: about 23g (general, CYX19Ti) Environmental Conditionsvibration: no change at 10gRMS, (20-2000) Hzconstant acceleration: 100g, 11msmedia compatibility: liquid or gas compatible with 316L4.4Reference conditionsmedium temperature: (25 ± 3) oCambient temperature: (25 ± 3) oChumidity: (50% ± 10%) RHambient pressure: (86-106) kPapower supply: (1.5 ± 0.0015) mA DC4.5Standard range sensitivity output and optional pressure formRangeFull scale output (mV)Pressureform RangeFull scale output (mV)Pressure form0~10kPa(30~120)±20G0~3.5MPa(60~150)±20G/s/A0~35kPa(40~120)±20G/A0~6MPa(60~130)±20S0~70kPa(20~140)±20G/A0~10MPa(40~110)±20S0~100kPa(50~145)±20G/A0~25MPa (30~100)±20 S0~200kPa(30~125)±20G/A0~40MPa(35~105)±20S0~400kPa(40~150)±20G/A0~60MPa(70~165)±20S0~1.0MPa(55~145)±20G/A0~100MPa(55~190)±20S0~2.0MPa(50~160)±20G/A 4.6 Basic parametersParametersTypical valueMax valueUnitFull scale output100250mVZero output± 1± 2mVNonlinearity0.20.5%FSHysteresis0.050.08%FSRepeatability0.050.08%FSInput / output impedance2.65.0kΩZero temperaturedrift (note 1)±0.4±1.0%FS, @25oCSensitivity temperaturedrift (note 2)±0.4±1.0%FS, @25oCLong-term stability0.20.3%FS / yearExcitation current1.5 (the maximum input voltage can be 10V)mAInsulation resistance500 (100VDC)MΩCompensation temperature (note 3)0~+50; -10~+70oCOperating temperature-40~+125oCStorage temperature-40~+125 Response time≤1 Housing and diaphragm materialstainless steel 316L O-ringnitrile rubber, silicone rubber Measuring mediumFluid compatible with 316L, NBR, silicone Life (25 oC)> 1 × 108 pressure cycle (80% FS)timesFilling mediumsilicone oil Sealing ringΦ 16 × 1.8mm (nitrile or fluorinated rubber (note 4)) Note 1 & 2. 0-10kPa zero temperature drift and sensitivity temperature drift: typical value is 0.5% FS @ 25 oC, maximum value is 1.2% FS @ 25 oC.Note 3. compensation temperature 0~ 50 oC for ranges ≤200kPa; - 10oC~ 70 oC.Note 4. temperature resistance range of seal ring is - 20 oC ~ 200 oC, low temperature performance is poor, When the temperature is lower than - 20 oC, please verify before using.5 Model structure selection5.1Model selection SeriesRangeModelOutline drawingCYX19-100kPa~10MPaCYX1901CYX1901P25MPa~100MPaCYX1902CYX32-100kPa~3.5MPaCYX3201 6 Schematic diagram and wiring mode IN + (red wire) - power supply positive IN - (black wire) - power supply negativeS + (yellow wire) - output positive S - (blue wire) - output negative7 Application TipsThe "floating" sealing structure of O-ring on the side wall is recommended for sealing the pressure sensor, which can avoid the front end being compressed and the stability being affected.Pay attention to protect the front diaphragm and the compensation circuit board at the rear end, so as not to affect the performance or cause damage to the pressure sensor.The shell cavity shall be designed with tapered angle as shown in the figure, which is easy for assembly and can prevent the seal ring from being scratched by right angle. During assembly, pay attention to the tolerance fit between the pressure sensor size and the inner shell of the transmitter. It is recommended that the cavity be processed according to + 0.02 - + 0.05 of the pressure sensor diameter to achieve the required air tightness.During assembly, it is required to place vertically and press down evenly to prevent the shell from jamming or damaging the compensation plate.Do not press the metal diaphragm with hands or hard objects to avoid damaging the pressure sensor due to chip deformation or perforation.When wiring, the pins should not be cut too short, the length is generally no less than 5mm, and the welding time is no more than 5s.The pressure lead-in tube at the back of G type pressure sensor shall be connected with the atmosphere; water, steam or corrosive medium shall not enter the reference cavity at the back of the sensor body.Avoid falling, crashing, etc., which will affect the stability of the product.In case of any change of pin lead, the label with the pressure sensor shall prevail.
