智能电容式液位计

Intelligent capacitive fluid level gauge

      、简介 Introduction

FY系列智能电容式液位计是我公司根据市场需求，自主研发的新代高科技液位计，其实用性和性逐渐被大中型化工企业所青睐，该系列液位计线路部分均采用新代微电脑处理技术，将传感器信号转化为数字信号，通过MCU进行温度，线性补偿和系列功能设置，可用于液体、油类、固体测量的液位（物位）测量，无可动部件。它不受水蒸汽，灰尘或冷凝的影响，具有长期运行稳定可靠，灵敏度高，线性度好，耐高温，耐高压等优点。FY系列智能电容式液位计全系列产品都具有现场校准功能，用户可通过按键进行：“零点”、“量程”自动校准，以适应各种复杂场所的不同要求，可广泛用于石油、化工、冶金、电力、造纸、制药等各个域。The intelligent capacitive fluid level gauge in FY series is the new generation high-tech fluid level gauge developed by out company independently according to market demand, its practicability ａnd progressiveness have been get recommended by those chemical industrial enterprises gradually. Such series fluid level gauge are partially adopting the new generation microcomputer processing technology, to convert the sensor signal into digital signal, by making the temperature, linear compensation through MCU ａnd the functional setting in series, it can be used for the fluid (substance) level measurement on the detection of fluid, oil ａnd solid materials, ａnd without moveable parts. It shall not be affected by the water vapor, dusts or condensation, has the advantages as stability ａnd reliability for long term operation, high sensitivity, quite good linearity, high temperature/ pressure resistance. All of the intelligent capacitive fluid level gauge in FY series have the function to make calibration on site, user can perform it through pressing the key for: automatic calibration of “zero point” ａnd “”measuring range, in order to accommodate to different requirements from various complex place, it can be widely used in various fields such as petroleum, chemical industry, metallurgy, electricity, papermaking, pharmacy etc.

   智能电容式液位计作为本质安全型产品符合 GB3836.1-2010《爆炸性气体环境用电气设备第1部分：通用要求》和GB3836.4-2010《爆炸性气体环境用电气设备第4部分：本质安全型“i”》的有关要求，防爆标志为：Ex iaIICT6 Ga，适用于 1 区、2区，含有IIA～IIB类，温度组别为T1~T5的爆炸性气体混合物的危险场所。As intrinsically safe product, the intelligent capacitive fluid level gauge complies with the relative requirements as per in GB3836.1-2010 –the Electronic Equipment Used in Explosive Gas Environment, Part One: General Requirement ａnd the GB3836.4.2010 – the Electronic Equipment Used in Explosive Gas Environment, Part Four: Intrinsically Safe Type “i”, its explosion-proof symbol is Ex iaIICT6 Ga, can be used in Zone 1 ａnd Zone 2, the hazardous place where  containing the explosive gas mixture in class IIA~IIB, ａnd temperature category T1~T5.

二、产品特点 Product feature 

1.实用性强，按键设置，键校准，任意两点标定,操作其简单。It has the strong practicability with key configuration ａnd one-key correction, calibration at any two points; its operation is remarkably simple;

2.采用数字软件滤波技术，不受气量和液位摆动的影响，既能快速跟踪瞬态变化，又能显示液位的平均效应，显示稳定准确。By using the digital software filter technique, it shall not be affected by the gas amount ａnd fluid level fluctuation, can both make the fast tracking on switching transients ａnd displaying the average effect of fluid level with stable ａnd accurate indication;  

3.智能型液位仪在18-28V的电压均可正常工作，满足任何型号的安全栅。The intelligent capacitive fluid level gauge can work under the voltage from 18 -24V generally, accommodate to the guard grating in any models.  

4.采用软硬件抗干扰和纠错技术，在非防爆场所亦无需隔离，直接入网，降低了电路复杂性，减少成本。By adopting the anti-interference ａnd error correction technologies with software ａnd hardware, it shall not need to be isolated in the non-explosion-proof site ａnd can be directly connected, reducing the complexity of circuit ａnd cost;

5.精度高，通用性能强。It has the high accuracy ａnd strong general performance capacity,
