BGK-MICRO Distributed Network Measurement System (herein after referred to Measurement System) is a new product based on the latest electronic measurement technology and manufactured by Geokon Instruments (Beijing) Co., Ltd. The system integrates all managements of users, measurement, data and communications on WINDOWS2000/NT/XP work platforms with great convenience and powerful support of project security monitoring and data processing.
BGK-Micro-40Measurement System has internal BGK-Micro-VR intelligent measurement modules for vibrating wire sensors, differential resistance sensors, differential transformers and strain sensors. The BGK-Micro-VR intelligent measurement modules can be selected and installed for VW instruments only. These Modules have 8 channels by themselves, so an essential 8-channel measuring system is available without any expansion. Each channel can connect with a standard sensor and up to 40-channel measurement system is available upon BGK-Micro-CH channel expansion modules.
The measurement system consists of PC, BGK-MICRO security monitoring system software (separately purchased), BGK-MICRO-MCU distributed network measurement unit (with Built-in BGK-MICRO Series Measurement Modules) and intelligent instruments (for independent network nodes) and achieves automatic measurement, data processing, graph output and abnormal measurement alarming for various monitoring instruments.
BGK-MICRO Security monitoring system software has friendly interface and simple operation for user to master and use.
