9400

Application
The 9400 series guided wave radar level transmitter is a breakthrough in cost effective very high accuracy, very high resolution liquid level sensing for heavy duty applications. Rochester Sensors’ GWR level sensor is the culmination of years of research into micropower impulse radar, time domain reflectometry and equivalent time sampling. Rochester Sensors Model 9400 liquid level sensor is used to monitor liquids such as fuels, chemicals, water, coolant, lubricants and other materials. The device is capable of maintaining very accurate level readings regardless of liquid. The 9400 can optionally be configured to accurately measure both fuel level and the level of dissimilar materials, such as water/fuel interface. The device emits a series of electromagnetic pulses down the sensor probe. Liquid/air interface, and dissimilar liquid interfaces provide a change in the characteristic impedance of the sensor probe, and create a reflection of the pulse. The time-of-flight of the reflected pulses is measured, and the liquid and interface levels are calculated.

• Maquinaria de construcción y minería
• Maquinaria agrícola
• Generadores de energía móviles y estacionarios, bombas y compresores

Como se muestra en la siguiente tabla, el modelo 9400 tiene muchas ventajas que otras tecnologías no tienen y tiene un costo similar a las soluciones ultrasónicas o capacitivas, pero mucho más barato que un típico producto de radar de ondas guiadas para aplicaciones de control de procesos.
