訂購注意事項(xiàng)
PT500-PS01產(chǎn)品訂購注意事項(xiàng)
1、產(chǎn)品量程選擇：
為了使產(chǎn)品精度、壽命、穩(wěn)定性等功能達(dá)到最佳效果，產(chǎn)品的量程選 擇參照以下公式計算：
量程 = 系統(tǒng)最大壓力 X （1.2-1.5）倍；
產(chǎn)品的實(shí)際測量壓力范圍，應(yīng)該在量程范圍的15%-80%；
2、產(chǎn)品供電及輸出：
供電范圍；直流12-30VDC；
繼電器開關(guān)量輸出的帶負(fù)載能力，驅(qū)動電流小于額定電流；
是否需要帶4-20mA變送輸出；
3、用戶要了解產(chǎn)品的測量介質(zhì)特性：
介質(zhì)規(guī)格、介質(zhì)溫度、介質(zhì)純度（是否含有雜質(zhì)或顆粒等）；
4、用戶要了解產(chǎn)品的安裝環(huán)境及安裝方式：
室內(nèi)或室外安裝；
環(huán)境溫度；
要求的密封等級；
設(shè)備的振動范圍；
安裝方式：螺紋、法蘭、特殊結(jié)構(gòu)；
安裝空間是否滿足產(chǎn)品外形尺寸；
1. Product range selection:
In order to achieve the best effect of product precision, life, stability and other functions, the range selection of the product is calculated according to the following formula:
Range = x (1.2-1.5) times of the maximum system pressure;
The actual measuring pressure range of the product should be 15% - 80% of the measuring range;
2. Product power supply and output:
Power supply range: DC 12-30vdc;
The switch output of the relay has load capacity, and the driving current is less than the rated current;
Whether 4-20mA transmission output is required;
3. To understand the measurement medium characteristics of the product:
Medium specification, medium temperature, medium purity (whether it contains impurities or particles, etc.);
4. Users should understand the product installation environment and installation method:
Indoor or outdoor installation;
Ambient temperature;
Required sealing class;
Vibration range of equipment;
Installation mode: thread, flange and special structure;
Whether the installation space meets the overall dimensions of the product;
