How to measure the melt pressure and temperature in a negative-pressure reactor

The melt temperature is around 300°, with a negative pressure of (-0.5MPA to -0.8MPA). Are there any sensors that can simultaneously measure temperature and pressure?

The pressure of the melt can only be measured with a vacuum gauge; as for the thermometer, you need to choose one that suits the temperature of your melt – there are thermometers designed for high temperatures as well

According to you, what is being measured is the pressure inside the reactor, which equals the melt pressure. What if there is pressure loss due to long delivery pipes and high melt viscosity?
