 
    876 系列压力变送器/ 传感器
大气压力传感器 
 
特性...
- 及时预热
- 大气压力测量范围:600至1,100或800至1,100百帕/毫巴
- 耗电量低(电池供电或太阳能供电)
概述/设计原理:
876系列陶瓷传感器具有良好的精度和稳定性,可用于大气压力的**测量。GEMS玻璃与陶瓷复合材料制成的电容传感器具有持续的热稳定性及低磁滞,简单设计,结果真实可靠。客户定制的ASIC保证了该系列产品的长期稳定性和高精度。低电压要求(低至5伏直流电),可使传感器运行于远程蓄电池或太阳能发电场合。集成安装架和1/8"压力连接管大大简化了安装.
运行原理:
玻璃与陶瓷复合材料的传感器检测大气压力变化,一旦压力升高或降低,电容也随之改变。电容变化由客户定制的Gerns ASIC的电路检测到,转换为线性模拟信号,输出信号与所施电压成正比.
