Barômetro Air Pressure Sensor Thies

  • Descrição do Produto

    • Piezo-electric barometric pressure sensor
    • High accuracy 0.3 hPa @ 25 °C
    • Scalable measurement range 600 ... 1060 hPa
    • Quick responding behaviour
    • Long-term sturdiness

    The sensor measures barometric air pressure. The instrument is designed for application in the field of meteorology and environmental protection, where high accuracy, quick responding behaviour, longterm sturdiness and reliability are required. The barometric pressure sensor measures the „ABSOLUTE AIR PRESSURE“.


    The measuring results are available in 3 different forms
    1. Analog voltage output: 0 V ... 5 V (Standard/default configuration)
    only on request, special configuration necessary
    2. Frequency output: 300 Hz ... 1100 Hz
    3. Digital output: RS485

    The sensor is a tempered, piezo-electric absolute-pressure sensor, which shows excellent thermal and mechanical
    stability.
