According to the scene environment to choose the appropriate radar thermometer

radar to choose according to temperature and pressure of liquid.

in case of strong corrosive liquid, such as hydrochloric acid, nitric acid is more suitable for the low-frequency rod type radar and good high frequency type. These two kinds of radar is designed in order to in the corrosive environment. In an airtight container, guided wave radar minimum thermometer can be installed on DN40 takeover, low frequency and high frequency bell bell radar can be installed on the takeover (minimum, the premise is not stirring, foam, steam, pumping air into vacuum state, if in these circumstances, should choose the DN100 hf radar minimum flange to install, low frequency radar to 6 flange to install.

in measuring more than 2 cm of bubbles, compared to the big bubbles, small bubbles are less likely to be radar electromagnetic wave penetrating. Under the same thickness, as it is not easy to penetrate the thick foam. This kind of circumstance should choose low frequency than high-frequency bell bell radar radar more applicable. If there is no adhesive foam, then selects the guided wave radar thermometer can easily penetrate bubble, right below the level of measuring bubble.

in a stirred tank, generally don't choose guided wave radar, the mixing of power, it is easy to guided wave radar cable into the propeller, or pull rod rod of guided wave radar is to bend. So can only choose to non-contact measurement of high frequency or low frequency of bell mouth radar.

under the condition of vacuum, the boiling point of liquid than normal atmospheric pressure and low a lot. In the 30 - there are a lot of liquids 40 ℃ began to boil. When there is no vacuum, the liquid was calm, the vacuum, 1 meter of the liquid will become three meters high, is boiling bubbles and tiny water droplets. This kind of circumstance, can only choose bell radar, and then to do some changes on the site.
