In this article, a temperature transducer is integrated into the pressure transducers to actually measure temperature signals of the transducers, so that pressure signals are corrected automatically and the measuring precision is improved.Abstract:
The utility model relates to a digital pressure transducer for measuring fluid pressure, and especially relates to an intrinsic safe digital pressure transducer. The intrinsic safe digital pressure transducer comprises a housing and a top cover. A pressure transducer probe and a circuit board are disposed in a cavity formed by the housing and the top cover. The circuit board comprises a power supply circuit, a signal amplifier, an analog-to-digital converter, a microprocessor and a communication interface. The intrinsic safe digital pressure transducer is characterized in that a temperature transducer is arranged between the pressure transducer probe and the circuit board in the cavity, and the temperature transducer is connected with the microprocessor. According to the utility model, the temperature transducer is integrated into the pressure transducer to actually measure temperature signals of the pressure transducer, so that pressure signals are corrected automatically and the measuring precision for the pressure transducer is improved.read more
