Purchasing Guide

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

  • When selecting the supply of level switches, it is recommended that enterprises prioritize checking key technical parameters such as measurement range, material compatibility, and protection level in product specifications based on the characteristics of the measuring medium (such as particle size and corrosiveness).
  • For different application scenarios such as chemical or food industries, it is necessary to distinguish the applicability of contact and non-contact level switches. For example, RF admittance switches are more suitable for viscous media, while ultrasonic switches are suitable for dusty environments.
  • When selecting suppliers, priority should be given to product matching, business qualifications, enterprise activity, industry performance, and enterprises with industry data support or platform statistical information to ensure supply stability and technical support capabilities.
  • When purchasing level switches under high temperature and high pressure conditions, it is necessary to pay extra attention to the temperature and pressure resistance indicators, and verify whether the supplier has successful cases or data support for similar scenarios.

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

Q

working principle The tuning fork level switch mainly uses the resonance principle of the tuning fork to measure the level state. Specifically, there are two sets of piezoelectric crystals pressed tightly at the end of the tuning fork. One set is the driving element used to generate electromagnetic excitation, causing the tuning fork to vibrate at a certain resonance frequency; The other group consists of detection components used to detect the vibration state of the tuning fork. When the tuning fork comes into contact with the measured medium, the vibration of the tuning fork
