MP3V5004DP Performance Issues

[jiajian_huang]

1.The pressure measurement range is 0-3.92 kpa. Whether the negative pressure can be tested is equivalent to the pressure measurement range of 0-3.92 kpa

2.Temperature compensation range is 10 to 60°C, so if it is 0°C or -10°C, what is the error range?

3.Operating temperature is 0 to 85°C. Can it work at -10°C? If it works properly, what is the error range? Thanks。

Hi,

The MP3V5004DP is a differential pressure sensor measuring a pressure difference between its two ports. This device is designed to operate with positive pressure only (P1 > P2). It cannot measure a negative pressure difference (output would be at ~0V).

We cannot recommend operating the MP3V5004DP below 0°C as it may cause a degradation of the functionality or even a permanent damage.

We can guarantee the MP3V5004DP specification and its parameters at the limited temperature range of +10°C to +60°C only. From 0°C to 85°C is the operating temperature range, any normal application is allowed, but when the temperature is below +10°C or above +60°C, the accuracy cannot be guaranteed. We do not provide any official error report for temperatures below +10°C.

Best regards,

Tomas

Hi Tomas，

If P1 is connected to atmosphere, P2 is connected to negative pressure, such as -2kpa, P1 is still larger than P2, the output is positive voltage, so is it available? Thanks.
