Brief introduction:

Intelligent( differential pressure) pressure transmitter conforms to FF specification and has a multi-parameter detection function through the innovative design of sensor and signal processing circuitry on the basic of 3151 ordinary intelligent (differential pressure)pressure transmitters. The new designed product has multi-parameter detection function that the pressure, static  pressure temperature sensor, medium temperature can be recognized simultaneously in a differential pressure transmitter. One user can select the desired part or all of the detection function according to his needs. The detection function makes a great improvement on the product performance of 3151 intelligent differential pressure transmitter as well as excellent fully digital field bus communications technology in line with FF protocol .

  With an exquisite appearance , The FF protocol smart pressure transmitter is easy to use and install so that it can completely replace 1151 or 3151 ordinary analog or smart ( differential pressure) pressure transmitters. Owing to all its varieties have increased the sensor’s accurate temperature measurement function of measured medium contacted with the inner transmitter, it can provide more site information to the user. Transmitter and the parts in contact with the measured medium part can be made of the appropriate anti-corrosion(corrosion resistant) materials according to the actual site conditions in order to adapt to different corrosion resistance.
