Self-test, self-calibration, self-diagnostic function - common sensors require periodic inspection and calibration to ensure that sufficient accuracy photoelectric sensors in normal use, these jobs generally require the use of the sensor from the demolition site to the laboratory or inspection department get on. For online measurement sensor is abnormal is not diagnosed in time. Smart sensor situation is much improved, first self-diagnosis function self-test from the sensor when the power is turned on, the diagnostic tests to determine whether the fault component. Secondly, based on the use of time online correction sensor which, microprocessor uses EPROM data exists within the metrological characteristics are compared proofreading. Vacuum sensor, using an advanced silicon micromachining technology to produce an integrated silicon pressure sensitive resistance element as a core element of the sensor is made of absolute pressure transmitters, the use of silicon - silicon direct bonding or silicon - Pyrex glass electrostatic vacuum reference pressure chamber formed by bonding, and a series of stress-free packaging technology and precision temperature compensation technology, which has excellent stability, high accuracy and outstanding advantages apply to all cases of absolute pressure measurement and control. Characteristics and uses a low-range chip absolute vacuum packaging, products with high overload capacity. Vacuum filled silicone chip isolated sensors, stainless steel film transition transmit pressure, with excellent media compatibility, suitable for the vast majority of non-corrosive stainless steel 316L gas liquid medium vacuum pressure measurements. The degree of vacuum used in various industrial environments infect its low vacuum measurement and control tension sensor | Tianjin Sensors | Xinfeng Xinfeng sensor provided by the Xinxiang purification technology Limited.
