What are the precautions for the use of pressure type thermometer

Pressure type thermometer note mainly include: the use of pressure type thermometer to use in the surrounding air temperature within a certain range and humidity no more than eighty percent of the environment. Pressure type thermometer should be installed on the no shock mounting plate vertically, so can reduce the additional error caused by the vibration. Bulb to dip in the measured medium, as far as possible make the package insert maximum depth, which reduces temperature package installation bolt the error due to heat and is frequently measured medium flow. At the time of installation, capillary to straight and distance apart with chuck, capillary tube bending is less than the prescribed scope. Pressure type thermometer work of humidity in half to three-quarters of the parts of the measuring range. In any case, a thermometer to avoid collision and impact vibration, etc. If the measurement of copper and copper alloy corrosion effect, to mark in the order.
