Ceramic Capacitive Pressure Sensors

Product Name: Ceramic Capacitive Pressure Sensors Model NO.: JC-CAK01. UCS2 Certification: CE Material: Stainless Steel Trademark: jiucheng Origin: Nanjing, China Product Description JC-CKA01 Ceramic Capacitive Pressure Sensor Overview:JC-CKA01 is a dry ceramic capacitive pressure sensor manufactured by KAVLICO Corporation in the United States. The ceramic is a recognized material with high elasticity, corrosion resistance, wear resistance, impact resistance and vibration. The thermal stability of the ceramic can make its operating temperature range up to -40 ~ 125 °C, but also has high accuracy and high stability. The biggest characteristic of dry-type ceramic capacitor thick-film pressure sensor is that the measuring range can be as small as 700Pa and overload resistance.The ability to reach a range of 10 times completely solves the shortcomings of other types of sensors that do not have a small range and poor overload capability in a small range. In addition to the range of a general sensor, its most distinctive feature is its positive and negative gauge functions. Such as: ± 7kPa and so on.The high output and wide range of dry-type ceramic capacitor thick-film pressure sensors are particularly suitable for manufacturing high-performance industrial control pressure transmitters. The large circular diaphragm surface is smooth and easy to install. It is the preferred sensor for pressure transmitter production in Europe and America such as ABB, SIEMENS, H&B, and VEGA.JC-CKA01 Ceramic Capacitive Pressure SensorFeatures:JC-CKA01 ceramic sensor has no liquid transfer function, no filling liquid, no process pollution, so it has a wide range of applications in the food, pharmaceutical and other industries, coupled with dry ceramic diaphragm, it is not affected by the installation direction, The pressure transmitter produced as a sensing element is widely used in various pressure measurement applications.Anti-corrosive dry ceramic capacitive pressure sensor has no intermediate liquid transfer, process pressure directly acts on the front surface of the ceramic diaphragm, the capacitance of the substrate electrode and the diaphragm electrode change proportion and pressure, and the value of capacitance changes by the laser Fine-tuning, sensor-specific signal conditioning circuitry ASICs amplify up to 4000mV of DC voltage, and built-in temperature sensors constantly measure the temperature of the medium and perform temperature compensation. When overloaded, the diaphragm is attached to the ceramic substrate without damage. When the pressure returns to normal, its performance is not affected. Completely solve the shortcomings of poor low-range overload capacity, is the proliferation of silicon diffusion sensor products. The standardized high output has extremely strong anti-interference ability, and the dedicated circuit board can carry out large scale migration (10:1). The sensor has high temperature stability and time stability, comes with temperature compensation, and can be in direct contact with most media.UCS2 Ceramic Capacitive Pressure Sensor Application:The pressure sensor element Ceracore UCS2 delivers a pressure-proportional voltage signal . We offer support for the integration of the Ceracore UCS2 into the customized application.UCS2 Ceramic Capacitive Pressure SensorBenefits:* Dry capacitive ceramic sensor* Basic ceramic material (99.9 % Al2O3 )* Extremely high overload limit* Absolutely resistant to wear* High temperature stability* High long-term stability* No hysteresis* Corrosion-resistant* Active electronics* sensor-specific signal conditioning* High-accuracy pressure measurement with temperature stabilityUCS2 Ceramic Capacitive Pressure SensorMeasuring Principle:The Ceracore UCS2 basic material is Al2O3(99.9 %), a highly resistant ceramic material for many aggressive gases and liquids. Cylindrical ceramic components (diaphragm, meter body) are bonded to form a high- strength, hermetically sealed pressure sensor element. With absolute pressure sensors, the vacuum of 3.0 x 10-6 mbar created in the production process between the diaphragm and the meter body remains permanently. This permits pressure measurements related to the vacuum. With gauge pressure sensors, the back of the diaphragm is vented, i.e. this sensor measures the gauge pressure relative to the atmospheric pressure. Elec- trically, the sensor element represents a plate capacitor whose capacitance change is the dimension for the pressure change. The capacitive measuring process satisfies the highest requirements concerning resolution and reproducibility. Together with the hysteresis-free behavior of the material Al2O3, it is the basis for the excellent specifications of the sensor. In addition, the Ceracore UCS2 is a dry measuring cell, i.e. there is no separating diaphragm or filling fluid which could influence the measurement. A further advantage of the capacitive ceramic sensor is its high overload resistance. After removal of the overload, it returns to the initial position without any damage or hysteresis.UCS2 Ceramic Capacitive Pressure SensorInputMeasuredvariableChoice of gauge pressure or absolute pressureMeasuringrangeGauge pressure measurement 0.1 to 70 bar,absolute pressure measurement 0.2 to 70 barUCS2 Ceramic Capacitive Pressure SensorOutput Values dependent on installationZero point0.50 V ± 0.05 V; applies to the respective lowerrange-value of the measuring rangeSpan4.00 V ± 0.05 VCharacteristiccurvelinear; max. non-linearity ≤0.2 % of spanLoad≥10 kΩ or ≤300 pF (with signal deviation <0.1 % of span)Rise timeapprox. 1 msSwitch-on timemax. 10 msLong-termstabilitymax. 0.1 % of span per yearOutput signal0.5 to 4.5 VTechnical Parameters:JC-CKA01 Ceramic Capacitive Pressure SensorPower Supply5±0.25 VDCResponse<10mSAccuracy(Linearity, Hysteresis, Repeatability)±0.1%(TYP),±0.2FS%(MAX)Zero output1000±100mVFull-scale output4000±100mVOutput load≥25kΩTemperature compensation range 0~85ºC,Temperature driftTCzero±0.01%FS/ºC,TCspan±0.01%FS/ºCStability<0.1%FS/yearSupply current≤2.2mAOperating temperature-40~125ºCInsulation resistance>2kVDimensionsφ32.36×11.4...12.7mmUCS2 Ceramic Capacitive Pressure SensorPower supplySupply voltage5 V DC stabilized, minimum 4.5 V / maximum 5.5 VInfluence of supply voltage: no influence on linearity / proportional on lower range-value/ proportional on span, no influence on temperature compensationCurrent consumptionMaximum 2 mA at a supply voltage of 5 VOperating conditions: InstallationOrientationArbitrary.
