Purchasing Guide

Based on real user feedback, we provide the following suggestions:

  • For procurement requirements that require the use of capacitive level switches, it is recommended to prioritize confirming the dielectric constant and temperature range of the measuring medium to ensure that the sensitivity and temperature resistance of the switch match the actual working conditions.
  • In the chemical or food industry, capacitive level switches are commonly used for powder or liquid level detection, and the installation method should be selected according to the container material (such as metal/non-metal) to avoid signal interference.
  • When selecting suppliers, reference can be made to indicators such as product compatibility, business qualifications, enterprise activity, industry performance, and industry data support to screen partners with stable supply capabilities.
  • If applied to high voltage or corrosive environments, it is necessary to verify key parameters such as the protection level (e.g. IP65) and electrode material (e.g. PTFE coating) of the capacitive level switch.

Knowledge Base

Q

Content description Capacitive level switch relies on the difference in dielectric constant of the medium to determine the point level. It has no mechanical rotating parts, is resistant to adhesion, and has a sturdy structure. It supports multiple installation methods such as contact probe, cable type, and non-contact external wall pasting. It is suitable for harsh working conditions such as high temperature, high pressure, strong corrosion, high dust, and viscous hanging materials. It only requires the dielectric constant of the tested medium to be ≥ 1.6 and can detect liquids and slurries
