Wear Resistance 2.2mA Dry Capacitive Ceramic Pressure Sensor
Pressure Sensor is a dry ceramic capacitive pressure sensor manufactured. 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.
* Rugged ceramic capacitor sensitive diaphragm
* Excellent corrosion and wear resistance
* High overload resistance, up to 10 times overload
* Flat round diaphragm, easy to install
* High precision and stability
* Fast response, no hysteresis
* Range migration ratio 10:1
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.
