液位变送器 HT 扩散硅液位变送器

bp93420系列液位变送器由全密封隔离膜充油液位传感器和仪表专用电路组成.具有测量精度高、稳定性好、寿命长、安装方便等特点。采用独特的工艺密封结构形式，防渗漏性能好，长期浸入液体中工作可靠。

根据被测液体的压强、密度、液位三者的数字模型关系，通过液位传感器把与液位深度成正比的液深压力测量出来，经放大电路转化成标准4～20ma电流信号。

bh93420 series hydraulic transmitter are made from well-sealed immerging oil-filled hydraulic transducers and manometers special circuit.have advantage og hign precision,good stability,long life and easy fixing .adopt special sealed configuration,so with good capability of anti-leakage.

accoding the relation between pressure,density and liquid level,the hydraulic transducers measure the liquid pressure which in direct ratio withdepth pf liquid ,then via amplificatory circuit ,the measured pressure is transfered to standard 4～20ma currentsignal(or standard voltage signal)

输出信号（signal output）:

二线制（two-wire）：4～20madc 0～10madc

二线制（three-wire）：1～5vdc 0～5vdc
