FIELD: measurement.
SUBSTANCE: invention relates to measurement equipment and can be used for measurement of process parameters, for example industrial process, using process sensor. Process transmitter (100) comprises insulating device (104), process sensor (106), compensating circuit (108) and output circuit (110). Insulating device (104) is configured to interact with process and comprises intermediate medium (111). Process sensor (106) is configured to generate a process signal which is a function of a process parameter which is transmitted through intermediate medium (111). Compensating circuit (108) is configured to compensate for process signal for response time of insulating device (104) and output compensated process signal. Output circuit (110) is configured to generate an output signal of the transmitter as a function of the compensated process signal.
EFFECT: technical result is high accuracy of obtained data owing to compensation of time constant by taking into account change in physical characteristics of insulating liquid.
