Abstract

Multi-point Temperature Measurement has always been very important aspect of physical instrumentation mainly in environmental and Industrial application. A multi-point temperature measurement system has been developed to measure temperature at different points simultaneously. This multi-channel system is designed specifically for measuring snow temperature at 28 different points In snow layers and this multi-point data is used in modeling of snow cover. The interfacing of such multi-channel system to Data acquisition system is one of the most critical design aspects, which affect the overall performance of the system. The temperature sensor system and Data Acquisition System may be working satisfactorily when operated independently but total system integrity is absolutely important when these two sub-systems are interfaced together. Further operating conditions in snow causes many performance and reliability issues to be tackled through proper design. This paper discusses the design aspects involved in the interfacing of the multi-channel temperature measurement system with the Data Acquisition System specifically for Snow hydrological applications.
