    CYBT1400 series of pressure and temperature integrated transmitters


    1 Introduction

    CYBT1400 series products are transmitters that integrate pressure and temperature measurement. Select high-reliability silicon piezoresistive pressure sensor, thermal resistance, etc. as the core components, after temperature compensation, digital circuit correction and signal conditioning, output standard industrial signals. The products have been carefully designed, component screening, process verification and curing, cyclic loading and aging, environmental simulation testing and other processes to ensure that each product is stable and reliable.

     

    2 Features                       

    ◆integration of temperature and pressure

    8 Precautions

    8.1 When installing the product, please pay attention to the protection of the temperature probe to prevent damage from bumps.

    8.2 The cable is made of PVC by default, if you have special requirements, please specify when ordering.

    8.3 When choosing high-temperature products, there must be good ventilation at the heat sink.

    8.4 Gauge pressure products with pressure ranges within 3MPa are equipped with vent holes or vent cables, and it is necessary to prevent the vent holes from being blocked.

    8.5 When working in a flammable and explosive environment, please supply power to the transmitter through the safety barrier.
