     Application in Central Air-conditioning Industry

     

    I. Introduction: 

    The air-conditioning pressure transmitter is a variation of DG series standard products. It is specially designed according to the features of the central air-conditioning system. The special pressure connector is especially suitable for measuring the pressure of the compressor and other parts of the central air-conditioning system. With adoption of the special thimble, a front-end technology of US, the transmitter has good seismic performance and stability.

    II. Major technical specifications:

    Measuring medium Various liquid, gas or steam that is compatible with 316 stainless steel
    Measuring range Gauge pressure of 0~0.05MPa to 0~10MPa, absolute pressure of 0~0.5MPa to 0~10MPa, composite pressure
    0.110MPa
    Output signal 4~20mADC (two-wire system) 0~10VDC, 0~5VDC, l~5VDC (three-wire system)
    Supply voltage 9~36VDC (two-wire system), 24±5VDC (three-wire system)
    Accuracy Class 1.0, class 0.5, class 0.25(composite errors including nonlinear, repeatability and lag errors)
    Installation method Thread installation
    Pressure connection 7
    16UNF inner thread
    Electrical connection Four-core shielded cable (IP65 protection level), DIN connector

    III Application

    (1) Central air-conditioning fan:
    Four-side ventilating embedded machine
    1. Grade I energy consuming standard of China Energy Conserving Products (high energy-consuming machine)
    2. Unique 700mm*700mm small board design makes indoor decoration more harmonious and elegant (2HP)
    3. Exquisite design of fresh air interface which brings in outside fresh air to avoid “air-condition disease”
    4. Streamlined air outlet design which eliminates the airflow noise
    5. Air suction port grating which can rotates for 90 degree enables you to choose installation direction as you like and is good for air filter-net replacement.
    6. Various control methods make it convenient for use.
    7. The pollution-proof movable air deflector and the long-acting filter screen on the ceiling can be easily cleaned and maintained.
