Gas Detection 11 Gas sensor modules feature state-of-the-art solid polymer sensor technology
EC Sense offers the TB600B and TB600C Gas Sensor Modules now with an I2C output. These sensor modules combine cutting-edge solid polymer sensor technology with a sophisticated circuit board, providing users with a simple and easy-to-use solution for gas sensing applications. These sensors were featured on the EC Sense stand at the recent Sensor + Test stand in Nuremberg.
The sensor module is designed to make gas sensing easy for users, with its small sensor signal transformed into a standardised digital output. The module detects gas, temperature, and humidity simultaneously, providing a low-power, compact, and reliable solution for any gas detection needs.
The heart of the sensor module is a solid polymer electrochemical gas sensor, a revolutionary innovation in the fi eld of electrochemical detection. The technology is based on the principle of electrochemical catalytic reaction, with the target gas generating a sensor signal that is directly proportional to the gas concentration. The EC Sense solid polymer sensors are small, robust, and reliable, have a fast response time, and consume no power with a long lifetime. They have a sleep mode and can be recalibrated by sending a command.
Users can integrate the TB600B and TB600C Gas Sensor Modules into their devices without worrying about sensor technology and calibration, allowing them to focus on their area of expertise. The modules are available with a standard UART digital output and the new I2C output. An evaluation kit is available that includes a UART/ I2C to USB adapter and easy-to-use testing software.

New hydrogen- compensated carbon monoxide sensor in 5-series format with extended lifetime is ideal for harsh environmental conditions
MEMBRAPOR provides a vast array of different electrochemical gas sensors for more than 25 gases in a variety of housings. They have recently announced the launch of the new Vantage series, with the same dimensions as 5-series sensors.
The new housing has been developed thanks to the fi nest engineering and over a quarter of a century of gas sensor experience. The sensor has been designed to operate in the harshest conditions, such as environments with high humidities and temperatures as high as 60 °C.
The fi rst sensor with Vantage housing is a CO sensor for use in fl ue gas/stack gas analysis; this is an H2-compensated, 4-electrode sensor with virtually no sensitivity to CO on the auxiliary electrode. Moreover, its temperature dependence can be kept fl at, resulting in exceptionally precise ppm readings.
MEMBRAPOR sensors are renowned for lasting for many years and the new Vantage housing offers the additional advantage of featuring a replaceable fi lter. While a typical CO sensor will typically last for three or more years, the fi lter itself has a signifi cantly lower lifespan. Once used up, nitric gases, such as NO2
, can pass
through, resulting in false negative signals. This is a dangerous situation; the resulting ppm reading may be far too low with respect to the current concentration of CO. In many applications, a fi lter has an approximate lifespan of 2 years, which is effectively the limit for critical measurement applications. Replacing the fi lter of Membrapor’s CO/VF-2000-4E can more than double the lifetime of the sensor.
