Precautions for selection of level switch


Release time:

2021-02-03

Common level switches include vibrating level switches, RF admittance level switches, rotary resistance level switches, etc. Because all kinds of level switches have their own characteristics and scope of application, even the same level switch, in the face of complex working conditions, also need to choose different models to adapt to it, in order to achieve better level measurement effect, the selection of level switch is very important. So, the level switch in the selection of the need to pay attention to what are the following points:

Commonlevel switchThere are vibrating level switch, RF admittance level switch, rotary resistance level switch and so on. Because all kinds of level switches have their own characteristics and scope of application, even the same level switch, in the face of complex working conditions, also need to choose different models to adapt to it, in order to achieve better level measurement effect, the selection of level switch is very important. So, the level switch in the selection of the need to pay attention to what are the following points:

I. Process Connection

Process connection is the key component of the instrument installed on the tank, pipeline and other equipment. It is generally divided into three categories: thread, flange, and clamp. When selecting process connection, it is necessary to select and customize the appropriate size, thickness and material according to site requirements. The process connection matches.

2. insertion depth

The insertion depth is the key to whether the instrument can accurately measure the level. The length of the insertion depth also depends on whether the instrument will be affected or damaged by the impact of materials. In order to make the instrument work more reliable and the measurement more accurate, it is counted as production.level switchThe length of the instrument can be customized according to the actual needs of users, providing a more reliable guarantee for the production of users.

III. Process Temperature

Different working conditions have different requirements for temperature, so choose andlevel switchThe matching temperature is quite necessary. If the working environment of the instrument is high, the level switch with the corresponding temperature can be selected.

IV. Explosion-proof Function

If the work site involves inflammable and explosive materials, or the explosive dust is easy to trigger the explosion hazard in contact with air, it must be considered to choose the explosion-prooflevel switchThe Tube-11 vibrating rod level switch, which is independently developed and produced by automation, has not only gas intrinsically safe and flameproof explosion-proof options, but also dust intrinsically safe and flameproof options to choose from, providing all-round safety guarantee for the vast number of users.
