Abstract
The utility model relates to a rapid online testing device for a pressure/differential pressure transmitter. The rapid online testing device comprises a pressure-producing device, a blow-off pipe, a pressure device, a first connecting pipe, a second connecting pipe, a first valve, a second valve, a standard pressure gauge and an electrical measurement unit. The pressure-producing device is a sealed container. The pressure-producing device has the first connecting pipe and the second connecting pipe. The pressure device is connected to the pressure-producing device. The first valve is arranged on the first connecting pipe. The second valve is disposed on the second connecting pipe. The front end of the first valve on the first connecting pipe is connected with the standard pressure gauge which is connected with the electrical measurement unit. According to the utility model, online detection can be carried out without dismounting the pressure/differential pressure transmitter, and online synchronous adjustment of an electrical part and a pressure part can be realized.
