Although MEMS technology can control the process accuracy within a small range, it is still difficult to accurately control the doping concentration of diffusion silicon, which directly leads to the existence of zero temperature drift and sensitivity temperature drift of MEMS sensor. Changes in the operating temperature range affect the sensor in two ways: they cause zero drift and they affect the output over the entire range. When the operating temperature range of the MEMS sensor is increasing, it is necessary to compensate the temperature of the MEMS sensor in order to reduce the drift phenomenon caused by temperature changes. However, the wider the temperature range, the more difficult the compensation technique, the greater the calibration effort, and the more difficult it is to ensure accuracy over the entire temperature range.
Smart Sensor ZXP6 series differential pressure gas pressure sensor
In order to solve the contradiction between the temperature range and the accuracy of the sensor, Beijing Smart Sensor Technology Co., Ltd. (hereinafter referred to as Smart Sensor) has launched the ZXP6 series of high-precision wide-temperature differential pressure gas pressure sensors through years of research and development and practice. The core of the pressure sensor is the MEMS pressure sensor and the special conditioning chip, which adopts the current advanced pressure sensor technology and highly integrated, low-power, high-precision digital signal processing technology, provides complete pressure calibration and temperature compensation, and obtains an amplified analog output signal, which can achieve a maximum error rate of only 1% in the whole temperature zone.
Smart Sensor ZXP6 series differential pressure pressure sensor is also widely used in a wide range of fields, and has been widely used in medical, industrial and consumer electronics and other fields, and has been highly recognized by the market and widely praised by customers. Among them, in medical applications, the ZXP6 differential pressure gas pressure sensor has become a key component of the ventilator gas system due to its excellent performance parameters and product characteristics. During the working process of the ventilator, the signal generated by the ZXP6 differential pressure gas pressure sensor can help the microprocessor adjust the motor, so as to adjust or maintain the air pressure required for the patient's inhalation and exhalation, and monitor the patient's breathing signal at all times to control the action of the respirator and synchronize it with the human respiration. In the use of another "life-saving device" oxygen concentrator, the ZXP6 differential pressure gas pressure sensor can accurately measure the pressure of the adsorption tower in the oxygen concentrator, thereby providing important data support for the oxygen supply adjustment of the oxygen concentrator to ensure sufficient oxygen supply, and at the same time, it can monitor whether the patient has started to inhale to avoid the waste of oxygen when not inhaling. In addition, the ZXP6 differential pressure gas pressure sensor is also applicable and plays an important role in many medical devices such as biological safety cabinets, spirometry, and respiratory function testing instruments.

Smart Sensor ZXP6 series differential pressure gas pressure sensor has excellent performance, which can be used for gas measurement with a range of -500-500kPa differential pressure and gauge pressure, and the working temperature range reaches 40~125°C. In addition, Smart Sensor ZXP6 differential pressure gas pressure sensor has two installation methods: patch and pin, designed and manufactured by advanced MEMS micromachining process, and the accuracy and stability of the product can reach ±1%FS through high-reliability packaging technology.
Smart Sensor ZXP6 differential pressure gas pressure sensor realizes high-precision monitoring in a wide temperature range, and plays an important role in many applications such as medical, industrial, and consumer electronics with advanced product performance. It is believed that in more and more market inspections, Smart Sensor ZXP6 differential pressure gas pressure sensor will be able to further provide customers with safe, reliable, stable quality, excellent experience, and reasonable price products and services, and then create higher product value.
