SENSING TOMORROW SMP131-TLD(H) Piezoresistive silicon gauge pressure transmitter Product introduction High performance pressure transmitter Main parameters Pressure types SMP131 compact pressure transmitter combined with all the latest available technologies of the modern electronic pressure measurement fields. It’s the most cost-effective products after 10 year’s research and development. The sensor adopts full-automatic linear and temperature compensation technology to ensure the efficiency and quality of mass production. Fully-sealed and isolated air cavity design to ensure the long term reliability. Signal transmitting module adopts original calibration technology to realize parameters setting easily without any tools. SMP131 compact pressure transmitter has unique technological advantage which is different from other ordinary products with the same price and its’ capabilities are equivalent to the most of the high-end products, which is the first selection of the most cost-effective products. Gauge pressure Pressure and level measurement Measuring range 5kPa-100MPa, please refer to the ordering information chapter Output signal Reference accuracy Measuring medium The fluid which compatible with wetted parts Disclaimer: all the data used in the product description is not legally binding.
