Winsen Electronics, as a professional gas sensing solution provider with over 30 years gas sensor manufacture experience, offers Ozone O3 gas sensor.
WPCH01 general type ceramic pressure transmitter has small size and light weight, it is convenient and easy to install. It adopts pressure sensor made by Winsen and it convert pressure into standard voltage signal output through a high reliable amplifying circuit and accurate temperature compensation circuit. The whole stainless delicate structure and plastic elements with high-strength enhance its anti-corrosion character, which make the product meet demands in different application occasions.
This ZC02 gas sensor Module adopts high-stability catalytic gas sensor, high-performance micro-computer processor, and infrared remote adjustment mode, which makes the module with high reliability and simple debugging. Besides, this module have sensor breakdown warning and zero calibration limit functions, avoiding module continuous alarm or no alarm because of the broken sensor. When the methane concentration in air gets higher than the alarm point, it will control the mining lamp to flicker, to remind the workers to ventilate or evacuate timely. When the methane concentration declines to normal point, this gas sensor module will control the mining light recovery the normal lighting status, so that the personnel and property safety is assured and unnecessary loss is avoided.
Winsen Electronics, as a professional gas sensor manufacturer, produce electrochemical ammonia sensor, NH3 sensor for industrial use, using electrochemical working principle.
Winsen Electronics produces F1013 micro flow sensor, adopting thermodynamic principle to detect the gas flow.
