DM-502-H₂ Hydrogen Sensor
Manufacturer: Teledyne| DetconDetcon Model DM-502IS-H₂ sensor is designed to detect and monitor H₂ in air over the range 0-1% by volume.
The sensor assembly consists of an electrochemical fuel cell mounted in an Intrinsically Safe stainless steel and ABS plastic housing that includes a splashguard with integral cal port, a signal conditioning control transmitter circuit, a base connector board and an explosion proof junction box.
The Intrinsically Safe sensor housing design allows direct contact of the target gas to the electrochemical sensor, thus maximizing response time, detectability and repeatability.
And because the Intrinsically Safe housing design does not use a stainless steel flame arrestor, it eliminates inaccurate readings due to target gas absorption.
