訂購注意事項(xiàng)
PT500-590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(jì)算:
量程 = 系統(tǒng)最大壓力 X (1.2-1.5)倍;
產(chǎn)品的實(shí)際測(cè)量壓力范圍,應(yīng)該在量程范圍的15%-80%;
溫度量程:測(cè)量溫度介質(zhì)區(qū)分,所需產(chǎn)品是測(cè)量介質(zhì)溫度或是測(cè)試環(huán)境溫度,訂購時(shí)與銷售人員說明情況;
2、產(chǎn)品供電及輸出:
供電范圍的選擇按產(chǎn)品的個(gè)輸出規(guī)格確定:
A、內(nèi)置電池3.6V1200mAh;
B、外部5VDC供電;
C、外部9-24VDC供電;
常規(guī)Modbus RS485-RTU 低功耗型數(shù)字輸出;
5位LCD顯示表頭;默認(rèn)采集時(shí)間1S/次;
3、用戶要了解產(chǎn)品的測(cè)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(jí);
設(shè)備的振動(dòng)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;
Precautions for ordering PT500-590 products
1. Product range selection:
In order to achieve the best effect of product accuracy, service life, stability and other functions, the range of the product is calculated according to the following formula:
Range = x (1.2-1.5) times the maximum pressure of the system;
The actual measuring pressure range of the product should be 15% - 80% of the measuring range;
Temperature range: distinguish between measuring temperature and medium. The required product is measuring medium temperature or testing ambient temperature. Explain the situation with the salesperson when ordering;
2. Product power supply and output:
The selection of power supply range is determined according to the output specifications of the product:
A. Built in battery 3.6v1200mah;
B. External 5VDC power supply;
C. External 9-24vdc power supply;
Conventional Modbus rs485-rtu low-power digital output;
5-digit LCD display meter; The default acquisition time is 1s / time;
3. Users need to understand the characteristics of the measuring medium of the product:
Medium specification, medium temperature, medium purity (whether it contains impurities or particles, etc.);
4. Users should understand the installation environment and installation method of the product:
Indoor or outdoor installation;
Ambient temperature;
Required sealing grade;
Vibration range of equipment;
Installation method: thread, flange and special structure;
Whether the installation space meets the overall dimension of the product;
