Waste water treatment plant Zimmerberg

Waste water treatment plant Zimmerberg

The aging Horgen and Thalwil wastewater treatment plants, situated near Zürich, Switzerland, require extensive renovation to enhance their cleaning efficiency. The two plants are therefore to be merged. The new, modern Zimmerberg wastewater treatment plant (ARA) will treat the wastewater of up to 78,000 inhabitants and industry from 2027. In the event of an extreme […]

MD-Profile system

Códigos de referencia de los productos: S431HD, S432HD, S431HA, S432HA MD-Profile gauges are designed to be placed within internally flush pipes. The system is suitable for geotechnical and structural applications, for which vertical or horizontal accurate profiling is needed. Its unique patent-pending centering device allows to keep the orientation of the whole chain in the […]

FAQ#116 – How do I configure a WR-Log digital node to read RS485 Sisgeo TIMED sensors?

Sisgeo digital instruments can operate in two powering modes: TIMED or ALWAYS-ON (for more information see F.A.Q.#094.A string of mixed instruments consisting of TIMED gauges and ALWAYS-ON gauges cannot work.The first thing to do is therefore to check that ALL connected instruments in your array are set to TIMED mode.You can check the powering mode […]

FAQ#095 – How long does a chain of digital sensors take to be read?

It mainly depends from the powering mode of the gauges (refer to FAQ#094 for the description of the powering modes). AN EXAMPLE WILL BETTER CLARIFY THE ANSWER. In a batch of 240 gauges, unless otherwise requested by the Customer, the addresses are settled from #001 up to #240. In a borehole is installed a chain of 30 […]

FAQ#077 – Which are the maximum cable lengths from instrument to datalogger?

The cable lengths depend from many factors, first of all installation and cable protections (screen, earth, etc…). Assuming that instruments are installed in a workmanlike, for the maximum cable lengths should be followed the next suggestions: DIGITAL INSTRUMENTS: see FAQ#73 ANALOGUE INSTRUMENTS: see both downloadable documents.

FAQ # 076 – ¿Por qué es necesario añadir una resistencia de terminación para el último sensor digitalizado de cada cadena RS-485?

Todos los instrumentos digitalizados SISGEO (IPI, inclinómetros, H-Nivel …) utilizan el protocolo de comunicación de serie RS-485. El protocolo RS485 contempla una resistencia de terminación. La conexión en cadena recomendada es de nodos de punto-a-punto (multipunto) como un modo BUS (línea). Estrella, anillo o multiplicar la conexión de red no se recomiendan. Los dataloggers SISGEO […]

FAQ # 073 – ¿Cuál es el número máximo de sensores digitales (RS-485, Modbus), el número máximo de cadenas y la longitud máxima de cable en una red RS-485?

Última actualización: Octubre 2021 Todos los sensores digitalizados SISGEO utilizan una interfaz RS485 con protocolo Modbus. 1.El número máximo de sensores digitalizados en una red RS-485 son 247 (teórico) 2.El número máximo de cadenas de sensores digitalizados que es posible conectar a la unidad maestra Modbus (como OMNIAlog o miniOMNIAlog) son 4. 3. Sobre el […]
