★ Features

※ Stable output with high sensitivity

The output of a typical strain gauge sensor is only about 10mv, while the full-scale output of a diffusion silicon sensor is about 100mv. The interference and noise factors have relatively small effects, greatly improving the resolution, and there is no dead zone near zero pressure.

※ High precision and good repeatability

The diffusion silicon piezoresistive pressure sensor realizes pressure sensing, pressure transmission, and electrical conversion on the same component, without intermediate conversion links, pressure hysteresis, or mechanical displacement deformation, ensuring minimal repeatability and hysteresis errors, with good linearity, stability, reliability, and long service life.

※ Good temperature characteristics

Due to the use of advanced technologies such as laser resistance adjustment and computer compensation, as well as clever control of diffusion concentration, full range temperature drift (sensitivity temperature coefficient) self compensation is achieved. Overcoming the defect of high temperature coefficient in semiconductor chips, the zero position and full temperature drift of the transmitter have reached a high level, expanding the operating temperature range.

※ Suitable for applications in hazardous and explosive fields and locations

The diffusion silicon pressure transmitter has the characteristics of low current, low voltage, and low power consumption, and belongs to the intrinsic safety explosion-proof product. It has obtained the explosion-proof certificate issued by the national safety explosion-proof organization.

※ High reliability and anti-interference performance

The product is made of stainless steel material and has a special protective structure. The circuit is designed with a series of protection measures such as lightning protection, anti-interference, overvoltage, and overcurrent, which improves the ability to seal and resist corrosion and harsh working environments. It is fully suitable for the needs of general industrial field measurement and control.
