Series 2200 - Hydrogen Area Monitors & Leak Detectors
Whether to ensure personnel safety or monitor industrial processes, many industries can benefit from hydrogen detecting technology.
Reliably monitoring the presence of hydrogen gas is critical wherever it is produced, used, stored or transported. Teledyne offers the Series 2200 to detect hydrogen with or without oxygen in concentrations from 15 ppm to 100%.
WRS Sensor
Teledyne’s 2200 Series relies on the patented Wide Range Hydrogen Sensor (WRS) which utilizes Pd/Ni thin films to measure hydrogen in low and high ranges.
The low level sensor is a MOS capacitor with a Pd/Ni plate for one side. The presence of Hydrogen changes the electric field causing a proportional change in capacitance.
The high level sensor is a Pd/Ni thin film resistor. This sensor has a thin film opalladium-nickel deposited on the silicon substrate that changes resistance in the presence of hydrogen.
The 2200 interprets these changes and displays the hydrogen concentration while also generating an analog signal that can be sent to external monitoring systems. No other gases or environmental controls are necessary and no oxygen is required for a reading. The WRS sensor also contains a temperature sensing element and on-board heater, keeping the sensor substrate at a constant temperature. This elevated, controlled temperature assures sensor operation is unaffected by gas temperature.
