Level switch

Introduction Liquid nitrogen (LN2) is widely used across industries, medical fields, and research laboratories as a cryogenic liquid, stored at extremely low temperatures of around -196°C. Maintaining the stability of liquid nitrogen distribution systems is critical to ensuring their efficiency during vaporization and distribution processes. Tuning fork level switches, known for their high reliability and […]

In an industrial setting, a common issue arises when a process tank is equipped only with a magnetic float level switch (magnetic float type) without a remote transmission feature, making it impossible for the central control system to monitor the level. In such cases, instrumentation solutions must be explored to provide remote level transmission. This

A rotary paddle level switch is an instrument used to detect the level of solid materials (such as grains, powders) in various industries like storage, chemicals, and food processing. Below is an overview of its working principle and common troubleshooting methods: 1. Working Principle The rotary paddle level switch mainly consists of a motor, gearbox,

1. Case Overview Instrument Type: RF Admittance Level Switch Failure Type: Abnormal indication in control room (intermittent alarms, unstable signal). Application: Installed below a pulverized coal bag filter, used for low-level detection of coal powder mixed with inert gas. Objective: To detect coal powder accumulation and trigger timely discharge to storage silo, preventing excessive build-up.

Introduction In the food industry, stringent requirements are placed on equipment used in production processes to ensure product quality, safety, and hygiene. Vibrating rod level switches and tuning fork level switches play a critical role in this domain, requiring careful attention to material, performance, safety, maintenance, and regulatory compliance. This article outlines the specific demands

Introduction: In the sand production process, monitoring material levels is critical to ensure the smooth operation of equipment. However, sand-making machines often face harsh conditions, particularly due to high dust content. These conditions frequently lead to malfunctions in domestically produced paddle-type level switches, as sand and dust enter the internal components of the device, accelerating

Biopharmaceutical reactors play a vital role in pharmaceutical manufacturing, presenting unique challenges for liquid level measurement. This document explores the suitability of radar level gauges to meet these demands by analyzing their principles, advantages, and potential limitations in this specialized field. Introduction to Radar Level Gauges A radar level gauge is a non-contact measurement tool

Coal silos generally fall into two categories: raw coal silos and pulverized coal silos. Each environment presents unique challenges for level measurement due to differences in dust concentration, humidity, and material properties. This article analyzes the characteristics of each condition and recommends suitable level detection solutions accordingly. 1. Level Switch Selection for Raw Coal Silos

1. What is a Float Level Switch? A float level switch is a device that utilizes the principle of liquid buoyancy to detect liquid level changes, trigger alarms, or control pump operations. When the liquid level rises or falls to a certain point, the float moves accordingly, activating an internal microswitch to output an on/off

A level switch, also known as a level sensor or level control, is a device used to detect and monitor the level of substances such as liquids, solids, or granular materials in a container, tank, or silo. The main purpose of a level switch is to signal when the material has reached a certain level
