Description
The MPn-5 semiconductor propane sensor adopts a multi-layer thick-film manufacturing process. A heating electrode, measuring electrode and metal oxide semiconductor gas-sensitive layer are integrated on an Al2O3 ceramic substrate and encapsulated in a metal housing.
When propane is present in the ambient air, the conductivity of the sensing material changes with gas concentration. This conductivity change can be converted into an electrical output signal through a simple measurement circuit.
MPn-5 provides high sensitivity to C3H8, excellent stability and enhanced resistance to common interfering gases. The sensor has achieved UL 2075 certification and is designed for a service life of up to 10 years, supporting OEM manufacturers developing residential, commercial and industrial combustible gas detection products.

Technical Support:
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, but the module will be 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 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 sales@winsensor.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.
