An apparatus for accurate temperature and pressure measurement in production processes is described. In designing the temperture pressure probe, novel features are described which include minimization of the thermal mass of the thermal probe, thermal isolation of the thermal probe from its surroundings, and generating turbulence in the vicinity of the thermal probe where it comes in contact with the fluid flow. Embodiments disclosed for the pressure sensor include a recessed position where fluid pressure transients are minimized, and a surface mounted pressure sensor that is useful where the pressure sensor of the first embodiment is likely to get clogged due to fluid composition.
