Kind Tips
1. Please use a stable and accurate constant voltage source (usually 10V DC) for excitation, because the millivolt output is ratiometric and will change with the input voltage.
2. This sensor has a low analog output level. Please keep the signal cables as short as possible to minimize electrical noise interference.
3. For longer transmission distances, use a signal amplifier.
4. During installation, ensure pressure ports are properly aligned. Do not over-torque the connection to prevent damaging the sensing element or affecting measurement accuracy.
5. Allow the sensor to reach thermal equilibrium with its environment before taking precision measurements, as temperature gradients can affect the millivolt output.
6. While the TO-8 package is robust, avoid exposing the sensor to corrosive chemicals or excessive vibration.
FAQ
Q: What is the advantage of a millivolt output pressure sensor?
A: It is easy to operate and can generate a weak voltage signal proportional to the pressure without the need for onboard electronic devices. It is cost-effective and highly reliable.
Q: Why is signal conditioning important with this sensor?
A: Because millivolt-level signals are susceptible to electrical noise, it is recommended to use an amplifier or signal conditioner near the sensor when outputting over long distances to improve its noise immunity and ensure accurate measurement.
