Expert’s answer: Rosemount 1151 temperature issues

Rosemount 1151 temperature issues? Yeah, those exist. All manufacturers build their tools for specific applications. That means their devices provide the most accuracy within certain ranges of temperature, humidity, pressure, and other factors.

When people ask how long a device will work outside of recommended ranges, we can only give an estimate. Thus, we suggest staying inside the range. If you expose your device to extreme temperatures, for example, then you may damage it or decrease the life of the device.

In regards to measurements, you’ll find that the accuracy in the manual often doesn’t match what you have in the field. If you want to find the real efficiency in your process measurement, read this article. The temperature factors into your accuracy; if your temps go out of your device’s range, then your accuracy will drop.

Therefore, you need to keep your devices within company specs. Doing otherwise just shortens the life of the device and skews your measurements.

These companies offer a good range of pressure devices:
