What to look out for when using pressure transducer sensor
The pressure transmitter is a kind of instrument that uses the tensioned steel string as a sensitive element. The inherent frequency of the internal element is related to the magnitude of the tension force. When the length of the string is determined, the variation of the vibration frequency of the string can be used to represent the magnitude of the pull force, that is, the input is a force signal and the output is a frequency signal, which is the basic mechanism of the vibrating wire type transmitter.
1. When the pressure transmitter is under pressure during operation, the power supply should not be strongly changed or the output should be interrupted. It is also forbidden to have excessive pressure to lose input and the output current is too large.
Second, the pressure input connector is connected to the media side of the catheter, after connecting the power for 2 hours to adjust the zero.
Third, must check whether the limit device is adjusted before use.
4. The pressure transmitter will slowly open the shut-off valves in the input pipeline. The measurement part establishes the pressure. The output DC value of the instrument corresponds to the pressure value.
