What happens to a pressure transmitter when the ambient temperature is too high?

Signal instability

High temperatures can cause the temperature inside the pressure transmitter to rise, which in turn affects the characteristics of the pressure transmitter and makes the output signal unstable.

Decreased sensitivity

Elevated temperatures cause the internal materials of the pressure transmitter UPB1 to expand, which affects the sensitivity of the sensor. In general, the sensitivity of a pressure transmitter decreases as the temperature rises.

Accuracy decreases

Changes in temperature cause all components within a pressure transmitter to have different coefficients of thermal expansion, which affects the accuracy of the pressure transmitter. In practice, the measurement accuracy of a pressure transmitter decreases as the temperature rises.

Shortened life span

In high temperature environments, the internal components of pressure transmitters UPB2S are susceptible to thermal expansion, thermal stress, and other factors, which can shorten their lifespan.

Reduced long-term stability

Temperature changes accelerate the aging and corrosion of pressure transmitter materials, thus affecting their long-term stability. In general, the higher the temperature, the lower the long-term stability of the pressure transmitter.

Components are affected

For the control circuit part of the pressure transmitter UPB9, high temperature will affect its components, resulting in parameter changes, which will cause measurement errors and make the instrument's measurement results less accurate.

Deterioration of interface sealing

Expansion and deformation conditions at high temperatures may lead to a reduction in the sealing of the interface, making it susceptible to leakage or vessel pressure relief.
