The sms based two-parameter sensor of a combined type (short message)

The description of a two-parameter sensor, which is able to measure pressure and temperature was presented. This sensor was developed by the authors of the paper based on thin-film baroresistor made of samarium monosulfide placed on a glass substrate and асhromel-alumel thermocouple. The sensor operates at temperatures of (-60)÷(+40) °С and pressures up to 70 MPa, has a speed of 0.1 s, has the area of volumetric strain measurements localization ~ 1 mm 3, is stable while being placed in concrete for more than 3 years. The sensor is designed for measurements in wet particulate media (concrete, soil, etc.). The measurements in the stiffening concrete and ground at the temperature range of (+ 20)÷(-50) °С were conducted to illustrate the capability of the sensor.
