Migatron RPS-2300 material level controller

RPS-2300 is a single sensor device,have 2 independent range control adjustment,LED indicator,and C type relay output . this makes the sensor ideal for high and low level control,or other applications that require two setpoints . the sensor head consists of Delrin production,14 inches and 36 inch sensor with epoxy surface,72 inch sensor uses Valox silicon surface . a sealed silicone rubber sensing surface is used,making this sensor best suited for environments where is a problem . the sensor also has a unique master-slave function,make many identical units available in close proximity to each other,without causing crosstalk interference . for example,if three sensors are needed in a close area,then one sensor acts as the main sensor,the other two sensors act as slave sensors . this is via the board X enter 、X output and GND completed by connecting . a sensor ( host ) will pass X OUT and GND terminal sends signal . they will be connected to the other two sensors ( slave machine ) of X IN and GND terminal .
