Maximum operating pressure of the pressure transmitter
Thread Content
Dear experts, I have a Rosemount 3051 pressure transmitter. It indicates that its calibrated range is 0–200 kPa, while its maximum operating pressure is 0–0.207 MPa. What does this mean? I also have a broken pressure gauge whose range is 0–250 KPa. Can the range of this Rosemount transmitter be changed to match that?
207 kPa is likely its maximum allowable operating pressure; exceeding this value may damage the instrument.
The maximum operating pressure is the upper limit for the safe and normal operation of the instrument; neither the measurement range nor the device pressure may exceed this value. Whether it can be changed depends on your actual situation; it should be possible
The operating pressure of the instrument must not exceed the range of 0–0.207 MPa (0–207 KPa); exceeding this range may damage the instrument. Gauges with a range of 0–250 KPa do not fall within this range, so they cannot be used.
Do you mean to replace the sensor by yourself? ? ?
The original 3051 pressure transducer indicated that its calibration range was 0–200 kPa, with a maximum operating pressure of 0–0.207 MPa; this means that the pressure range of the medium being measured lies within 0–200 kPa, and the maximum pressure that the pressure transducer can handle is 0.207 MPa； The range of the replacement transmitter is 0–250 kPa, and the pressure variations of the medium being measured fall within this range; thus, it is not possible for the pressure to exceed the transmitter’s measurement capabilities ； On the other hand, the pressure range ratio of the 3051 model is 100:1; changing the upper limit of the range from 250 kPa to 200 kPa has no significant impact on measurement accuracy. Therefore, replacing it with a 3051 pressure transducer operating at 0–250 kPa is completely fine.
Well, I misread it; thanks to the friend “zyzs”. Indeed, when the original transmitter has a range of 0–250 kPa, the maximum pressure of the medium can reach 250 kPa; therefore, a transmitter with a range of 0–200 kPa cannot be used as a replacement. Its operating pressure is 0.207 MPa, which means that its sensor can withstand a maximum pressure of 0.207 MPa, or 207 kPa. Hence, it is not possible to change its range to 0–250 kPa in order to use it as a replacement.
