Highlights
The Dräger SensorAlive is an electrochemical sensor with an integrated gas generator. The gas generator enables daily automatic sensor testing with hydrogen sulfide (H2S) as the test gas. It also alerts when the sensor inlet is clogged, preventing gas from reaching the sensor. Daily bump tests help to improve the safety of your gas detection system and allow for extended preventive maintenance intervals.
Dräger SensorAlive Functional Description
Dräger SensorAlive is a self-testing H2S sensor compatible with the Polytron 8100 transmitter and the PointGard 2100 standalone gas detection system running the latest firmware.
LifeTest: a daily bump test
SensorAlive performs a LifeTest on a daily basis to check the function and sensitivity of the integrated electrochemical sensor. The LifeTest consists of two sequential activations of the gas generator, a sensitivity test, and an obstruction test of … More Information
the sensor using 2 internal nozzles. A single test takes about 8 minutes to complete. The complete LifeTest process, including the conditioning of the gas generator, performing two sequential tests, and evaluating the sensor data, extends over a period of approximately 8 hours. During this time, the sensor retains its ability to detect gas.Extended calibration interval
Calibration of the electrochemical sensor is still required at regular intervals. During a calibration, the gas generator is also calibrated by SensorAlive at the same time.
The calibration interval of electrochemical sensors can be extended when usin … More Information
g SensorAlive. The calibration interval can be determined and adjusted according to application requirements as SensorAlive performs a daily check and issues a warning or error message if there is a deviation.Proven measuring technology
As with all DrägerSensor® electrochemical sensors, the Dräger SensorAlive offers fast response, high accuracy and stability, long service life, and established principles of intrinsic safety for electrical explosion protection.
Coupled with the Dräger … More Information
Polytron 8100 transmitter, Dräger SensorAlive provides access to proven measurement technology, permitting usage in Zone 1 / Div 1 rated hazardous atmospheres. Remote sensor installations up to 30 meters (100 feet) away from Polytron 8100 transmitters are supported.The Dräger SensorAlive is also plug-and-play ready thanks to built-in electronic intelligence and pre-calibration.
