series of high temperature pressure sensor - DX100T

Product name:

Dx100T series of high temperature pressure sensor

Product Description

DX100T series High temperature pressure sensor,use ceramic thick film sensitive components and Sapphire core, designed for high temperature range test conditions and manufacturing. It responds to the medium temperature zone width, thus broadening the range of the sensor, is a high-temperature environment detection conditions best choice .

DX100T is the use of ceramic material with a special process refined, dry ceramic Piezoresistive ceramic pressure sensor, is a recognized high elasticity, resistance to corrosion, abrasion resistance, resistance to shock and vibration. Ceramic thermal stability characteristics and its thick film resistors can make its working temperature range up to-40 °C ~ 150 °C, and measurement of high precision, high stability. Electrical insulation > 2kV, output signal strong, long-term stability. High performance, low-cost ceramic sensor will be the development direction of pressure sensor, in Europe and the United States have a comprehensive alternative to other types of sensor trend in China, more and more users use ceramic sensor replacement diffusion Silicon pressure sensor.

Sapphire by Crystal insulator elements, no lag, fatigue and creep phenomena; Sapphire has a very good elasticity and insulation characteristics (1000 ° c). the temperature insensitive, even in high temperature condition has also good work characteristics; Sapphire anti radiation characteristics of a very strong; in addition, Silicon-Sapphire semiconductor sensing element, no p-n drift, and therefore can be applied to all kinds of complicated Environment Forum .

The sensor consists of a double-diaphragm consisting of: titanium alloy measurement diaphragm and titanium alloys receive diaphragm. Printing there are Epitaxial of strain sensitive bridge circuit of the diaphragm, Sapphire is-fusion-welded in titanium alloy measurement diaphragm. The measured pressure delivered to receive the diaphragm. The pressure, producing titanium alloy receives the diaphragm, the deformation is deformation of SI-Sapphire sensitive element perception, its bridge output will change, changing amplitude and proportional to the measured pressure. Bridge circuit the imbalance of the bridge, the signal is converted to a voltage signal output.

Working principle

Corrosion-resistant ceramic pressure sensor without the pressure of the liquid delivery, directly at the front surface of the ceramic diaphragm, which produces a slight deformation of the diaphragm, thick film resistor printing on ceramic diaphragm back, connecting into a Wheatstone bridge (closed), due to the resistance of piezoresistivity, make electrical bridge creates a pressure proportional to the height of linear, and excitation voltage is proportional to the voltage signal, the signal according to the standard pressure ranges different calibration 2.0/3.0/3.3mV/V, etc, can be and is compatible with strain gauge sensor. By laser calibration, sensor with high temperature stability and stability in time, sensor comes with temperature compensation 0 ~ + 70 ° c, and can and most of the media in direct contact with .

DX100T Ceramic sensor because there is no liquid delivery role no filling, no process of pollution. Therefore in the food, pharmaceutical and other industries has a wide range of applications, combined with the ceramic diaphragm is dry, it is not subject to the direction of impact, its installation and Germany Hirschmann series connector with pressure transmitter is widely applied in various measuring pressure of the arenas
