Ordering tips
1. Determine Pressure Range: Identify the full range of pressures that the transmitter will need to measure. Ensure the transmitter you select can accurately measure within this range to avoid errors and potential damage.
2. Accuracy Levels: Understand the accuracy requirements for your application. Different transmitters offer varying levels of precision, so choose one that meets your specific needs for accurate data.
3. Mounting Options: Identify how the transmitter will be mounted in your application, whether it requires direct mounting, bracket mounting, or integration into a panel.
4. For special requirements such as strong vibration, instantaneous impact force, strong electromagnetic or radio frequency interference, please inform our company and specify them in the order.
5.Mounting Options: Identify how the transmitter will be mounted in your application, whether it requires direct mounting, bracket mounting, or integration into a panel.
