OEM 3151 differential pressure transmitter
PMD3051DP/HP Differential pressure / high static pressure differential pressure transmitter is a pressure signal
measured by the low pressure side as the reference end. it has two ports and process pipe connection.
The working principle of metal capacitance differential pressure / high static pressure differential pressure transmitter is
that when the pressure acts indirectly on the surface of metal measuring diaphragm (elastic measuring element) of
different thickness through isolating diaphragm and conductive medium, the diaphragm produces small deformation, the
maximum shape variable does not exceed 0.1mm, and the high precision measuring circuit converts this small deformation into a voltage signal which is linearly related to the differential pressure signal, which is linearized.
Temperature compensation, and then use a special chip to convert the voltage signal into an industrial standard 4-20mA
current signal or 1-5V voltage signal. The high precision integrated circuit adopted by the high sensitivity of the metal
capacitance pressure sensor and the measuring diaphragm detection circuit contains the linear and temperature
compensation circuit inside, so the whole transmitter can achieve high precision and high stability.
Metal capacitive pressure sensor has high overload resistance and excellent performance in micro-pressure
measurement, and it is also a necessary product in a variety of complex industrial environment.

Migration characteristics
|
when the minimum range (range compression ratio is 40: 1), the maximum positive
migration zero is 39 ≤ 40 times the upper limit of the range. The zero point of large negative migration can be the lower limit of range, and the absolute pressure transmitter has no negative migration. (no matter what the output form is, after positive and negative migration, the upper and lower limits of the range shall not exceed the limit of the range.) |

Installation position
inflfluence |
the maximum zero error not larger than 0.10kPa can be produced, and this error can be
eliminated by correction, which has no effect on the measurement range. There is no effect on the rotation of the measuring body relative to the flflange. |

Stability
|
+ 0.2% ≤ 12 months of the maximum range
|
|
|
||
|
Temperature effect
|
+ 0.2% ≤ 20 °C with zero and range temperature error of maximum range
|
|
|
||
|
Static pressure effect
|
after the static pressure 14MPa is stable, the zero error is + 0.25% of the maximum
range range, and the zero point of the transmitter can be eliminated according to the actual static pressure adjuster before installation. After the HP static pressure 31.2MPa is stable, the zero error is less than + 0.5% of the maximum range, and the zero point of the transmitter can be eliminated according to the actual static pressure adjustment before installation. |

|
|
|
||
|
Load effect
|
as long as the voltage of the input transmitter is higher than 12V, there is no load effect in the load working area.
