FAQ#073 – Which is the maximum number of digitized sensors (RS-485, Modbus), the maximum number of chains and the maximum length of cable in a RS-485 network?
Last update: October 2021 All the SISGEO digitized sensors utilize a RS485 interface with Modbus protocol. 1.The maximum number of digitized sensors in a RS-485 network are 247 (theoretical) 2.The maximum number of digitized sensors chains that is possible to connect to Modbus master unit (as OMNIAlog or miniOMNIAlog) are 4. 3. About the maximum […]
FAQ#011 – Are the air bubbles present in the liquid mix cause of errors?
Sisgeo liquid mix is de-aired at factory and it is supplied sealed in special tank. However in the DSM reference gauge there is a high sensitive sensor which is able to monitor the weight of the liquid within the reservoir. In the case of the air bubbles come over decreasing the level of the liquid […]
