How the light emitter works
A transmitter is a device that can transmit a signal at a certain frequency. It is a relatively general concept. It is widely used in various civil and military equipment such as television, broadcasting, communication, alarm, radar, remote control, telemetry, and electronic countermeasures. Transmitters can be divided into four categories: frequency modulation (FM), amplitude modulation […]
The working principle of zirconia oxygen analyzer
Oxygen analyzer is an industrial online process analysis instrument, not only widely used in heating furnaces, chemical reaction vessels, underground wells, industrial nitrogen production and other occasions in the detection of oxygen concentration in mixed gases, but also widely used in boiler water dissolved oxygen, sewage The detection of dissolved oxygen in the drainage outside […]
The use principle of vacuum gauge controller
The meaning of vacuum refers to the state of gas below one atmospheric pressure in a given space, which is a A physical phenomenon. In vacuum technology, the vacuum system refers to the atmosphere and generally refers to a specific space Part of the substance inside is discharged, so that the pressure is less than […]
What are the Differences between Gas Detectors and Gas Analyzers?
Comparison of several major differences between gas online analyzer and gas detection alarm: 1. Structure The structure of the gas detector is relatively simple, only including the probe (sensor) and the sensor signal conversion circuit part. The gas analyzer is not only equipped with probes (sensors) inside, but also has a complete set of gas […]
We Need to Understand The Precautions for Using Hydrogen Sulfide Detection Alarm
Hydrogen sulfide detectors are widely used in petroleum and petrochemical companies, and play a very important role in preventing poisoning accidents and reducing casualties. The hydrogen sulfide detector is an important monitoring instrument for safe production. Its main function is to detect the concentration of hydrogen sulfide gas in the air. When the concentration in […]
The Structure and Working Principle of the Centrifuge Oxygen Content Analyzer
The centrifuge oxygen content analyzer is composed of a scrubber, a dewatering filter, a fine filter (organic filter powder), a condenser, a flow meter, a gas analyzer, a complete set of sampling processing system and calibration system, and a sampling probe The unexpected part is installed inside a calibration box. Gas analysis instrument is the […]
Simple Operation Method of Portable Gas Detection Alarm
Portable gas detection and alarm devices are widely used in petrochemical industry, restricted space operations, and hot fire maintenance operations. In fact, the use of portable gas detection and alarm devices is relatively simple. Turn on Long press the power button to start the portable gas detection alarm instrument, and the instrument can enter the […]
Main Features and Precautions for Use of Magnetic Mechanical Oxygen Analyzer
Main features: Compared with the thermal magnetic analyzer, the magnetic mechanical oxygen analyzer has the following characteristics: ① It is an analyzer that directly measures the paramagnetism of oxygen. During the measurement, it is not affected by changes in the thermal conductivity and density of the measured gas. ② The linear scale is within the […]
How to Choose A Suitable Gas Detector for Limited Space Operations
Limited space refers to the narrow closed or partially closed space at the entrance and exit, such as cellars, cabins, storage tanks, pipelines, basements, sewage tanks (wells), biogas tanks, septic tanks, sewers, fermentation tanks, etc. Some hazardous toxic gases are concealed and difficult to detect, and multiple hazards may coexist. Use a limited space gas […]
