1. Based on strain gauge technology; 2. High accuracy, good long term stability; 3. Suitable for high pressure measurement.

UPB7 strain gauge pressure transmitter uses advanced metal foil strain gauges as sensing element. Those strain gauges consist a Wheatstone bridge and can feel the changes of the strain gauge’s resistance and convert these changes to “mV”electrical signal, the signal will be amplified to standard current or voltage output after it is conducted by the special amplifiers.

As the sizes of strain gauges are very small and can be designed so many different types to suit different situations, the transmitter’s pressure port is designed flush diaphragm or cavity for user’s option, the application of UPB7 strain gauge pressure transmitter is very wide these days, it is suitable for the measurement of middle pressure and high pressure .
