FIELD: technology for measuring pH-values or oxidation-restoration potentials, temperatures, conductivities or turbidity of liquids. ^ SUBSTANCE: in accordance to the invention, liquid or gas sensor is made of SM sensor module and SMK sensor module head with possible interconnection by insertion into one another. In assembled state the modules ensure exchange of data and power through galvanic-decoupled transmitting route. Replaceable ST2 module is provided, different from SM module due to absence of sensitive element MD and presence of digital-analog converter DA. Given module is made with possible connection to SMK head of sensor module and is used to simulate the measured value. ^ EFFECT: possible simulation of measured values, which is necessary for testing the whole informational chain between the SMK head and the central station. ^ 2 cl, 5 dwg |
