What is the relevant knowledge of thermal conductivity gas sensor MTCS2601?

Thermal conductivity gas sensor assembly MTCS2601 sensing principle

The sensing film and the silicon wafer of the MTCS sensor are equipped with two metal integrated thin film resistors, which are used as sensing elements and temperature sensors, respectively. The power required to operate this miniature sensor is usually 2mW, making this type of sensor particularly operable at low power. The thermal conductivity/diffusivity of the gas changes the temperature of the sensing resistor. The output signal is linear with the gas concentration without saturation effects, and has nothing to do with the flow rate.

Swiss Neroxis provides gas and pressure sensors, pre-calibrated modules and online probes to cover a variety of applications in the environmental and industrial control fields. network agent Neroxis full range of products, including sensors, modules, online probes and so on. The key advantages are as follows:

Miniaturization of sensors

Low energy consumption for sensors and modules for portable instruments

Provides pre-calibrated modules for temperature, humidity, and pressure compensation that can be directly incorporated into OEM equipment

The working principle of the gas micro thermal conductivity sensor (MTCS) relies on the transfer of heat flow from the heating resistor located on the insulating dielectric film to the cold part of the device. The heat flow directly depends on the conductivity of the gas. The principle is to measure the signal of the heating part and the "cold" part of the device at room temperature.

High-speed response hydrogen sensor module based on MTCS2601

This micro OEM module can be installed at any time as a bare board module. It integrates a rugged silicon micromechanical thermal conductivity sensor (MTCS2601) and temperature compensation function. Optionally, a relative humidity sensor (SHT21) and a pressure sensor (MS5803-01BA) can be integrated on the module. Relative humidity sensor (SHT21) and pressure sensor (MS5803-01BA) can be selected on the module. The thermal conductivity sensor is integrated on the chip, and its principle makes the small H2 measurement/alarm system in the air have low power consumption and long-term stability. Download specific firmware with selected parameters in the Flash MTP microcontroller to modify the full-scale range and measurement rate.

Application of thermal conductivity gas sensor MTCS2601

The thermal conductivity gas sensor MTCS2601 can be used in many applications. Due to the different specifications of different applications, Neroxis has developed a module for MTCS2601 that can work under a variety of conditions.

Neroxis provides an optimized calibration procedure for each use condition (H2, temperature, relative humidity and pressure range; background gas) in order to obtain the required H2 accuracy more economically.

The MGSM module based on the thermal conductivity gas sensor MTCS2601 can be used for the following applications:

H2 security alerts in home automation and industrial environments

H2 safety in production (electrolysis) and storage (fuel tanks, batteries)

H2 fuel safety in the transportation industry (cars, trucks, buses, airplanes and ships)

H2 fuel safety and monitoring in power plants

Miniature H2 sensor for fuel cell

Versions with ATEX modules can be requested from OEMs on demand: considering the final product certification, this method must be carefully verified.
