OLS710D3SH数据手册传感器变送器的浮子液位传感器规格书PDF

描述 Description

The OLS7 series is a liquid level sensor for single point level detection. The sensor has an infra-red emitter and detector aligned within an accurately shaped cone to give good optical coupling when the sensor is in air. This coupling is greatly reduced, when the sensor is immersed in liquid, as the infra-red light escapes through the liquid rather than being reflected back to the detector.

特性 Features

• Low cost general purpose liquid level sensors

• High reliability optical sensing

• External mount via 1/4\"NPT thread

• High and low output versions
