MP-7 Carbon Monoxide GAS SENSOR
|Characteristics:||High sensitivity to CO|
|Working conditions:||Loop Voltage：≤10V High temp.heater voltage：5±0.1V Low temp.heater voltage：1.5±0.1V Heater consumption：≤240mW|
|Notes:||Low temperature 90s detection, high temperature 60s cleaning|
MP-7 adopts advanced planar construction production technics, using MOS material formed by micro AL2O3 ceramic tube and heater, electro-down-lead be fetched out, and are fixed into a metal base and cover. Adopting low and high temperature circling detection: when low temperature （VH=1.5V）, it detects CO, Conductance of sensor bigger along with CO concentration in air; When high temperature（VH=5.0V）, clean other gases, using simple circuit could change the conductance, change it to be output signal which relatively to the gas concentration.
- They are used in gas leakage detecting equipment in family, industry and commercial field, fire resistance/ safety detection system.
- CO gas leakage alarm and detector
- High Sensitivity to CO
- Mini Size
- Fast response and resume character
- Excellent Stability and long life

Customized technical design and function, LOGO and package are available without extra charge (including molding fee) for mass volume.
The sensors don't have sleeping mode. It can be set in program if needed.
All Winsen products go through strict inspections and tests to make sure they are 100% qualified before shipping out.
The sensor has been fully tested (not calibrated) before leaving the factory. However, after transportation and storage, the environment conditions change, and the surface of the sensor absorbs moisture, mixed gas, pollution matters, etc. It is recommended that customers perform aging and calibration after sensors become stable according to the program and use occasions of the whole device.
15﹪-90﹪RH without condensation,greater or less than this range or long-term high temperature and high humidity will affect the life of the sensor.
Our sensors are certified with UL, CE, 3C, ROHS, anti-explosion, fire prevention, and coal mining safety according to different applications. And we provide assistance for new certification.
Many factors can cause the sensor to fail such as broken wires in transportation, poisoning, falling off of the sensitive material, damage to the heating wire (device), etc. Please find specific cause in each category with Winsen’s aftersales.
Winsen provides professional consultation and service before and after sales. We will recommend the best fitting sensor for your demand. If you have any problem, don’t hesitate to email us to email@example.com
Due to high volume of daily incoming emails and time zone difference, we may not be able to reply your emails immediately. But we will reply to your inquiry in 24 business hours.
