FIELD: measuring equipment.
SUBSTANCE: proposed group of inventions relates to means for measuring technological variables of production processes. Process transmitter (12) comprises a two-wire process control loop and is configured to measure the process variable of the production process. Said process transmitter (12) includes process variable sensor (20) that detects a process variable and, in response, generates an output signal of the process variable sensor. Sensor circuits (22) are connected to process variable sensor (20). Sensor housing and output circuits (24) are arranged in housing (34). Sensor circuits (22) are electrically connected to housing (34). Wireless sensor circuits (22) are connected to output circuits (24). Also, an appropriate method for obtaining an output signal from such a transmitter is implemented.
EFFECT: this group of inventions makes it possible to reduce the influence of AC noise from a two-wire loop that affects the measurements using a sensor circuit.
