Abstract
The article is devoted to the preparation and processing of the signal
from the temperature sensor, operating as part of
a multi-purpose equipment for field trials. The possible types of sensors, justifies the choice
for testing semiconductor
sensor LM335 (National Semiconductor). Arrange a controlled PC temperature in real time. Data program provides two
modes of operation: continuous and the control signal. Continuous mode allows you to build a time dependence of the
sensor signal at its
output on the operating mode, as well as the sensor temperature setting in different external process-
es. Based on the analysis of these dependencies it is proposed to use mathematical simulations to obtain an a priori esti-
mate temperature limit at the end of the transition process. The main objective of the work
- the definition of the pos-
sibility of using this sensor to monitor the temperature of permafrost. Methods of obtaining and processing of signals
has been used in equipment for static probing produced LLC "Scientific-Technical Center PEAK-TECHNOSERVICE".
