Description
The Bently Nevada 350800-01-180-00 is a flameproof, continuous diffusion catalytic bead hazardous gas sensor, designed for reliable detection of combustible gases such as methane (CH4) and hydrogen (H2). It integrates a catalytic bead impregnated with a catalyst to promote oxidation and a reference bead treated to inhibit oxidation, forming a Wheatstone bridge when connected to a 3500/63 Hazardous Gas Detection Module. Gas presence increases the catalytic bead temperature and resistance, unbalancing the bridge proportionally to the gas concentration.

This sensor is approved for operation in ambient temperatures from -40 ºC to +200 ºC, and its flameproof housing allows use in Zone 1 hazardous areas, facilitating sensor replacement without compromising safety. The sensor features a 180-inch lead, is constructed with a stainless steel body, and incorporates an integral sintered flame arrestor, ensuring durability in harsh industrial environments.

Designed for long-term, reliable operation, the 350800-01-180-00 has a minimum sensor life of 2 years and a typical life of 5 years under normal service. It offers excellent performance stability, with long-term zero drift < ±2.5% LEL per month and sensitivity drift < 2.5% per month at 20 ºC, 50% RH, and 101 kPa. The sensor resists poisoning by HMDS with T50 > 75 minutes and maintains reliable operation under shock of 250 g and vibration of 5 g from 10 Hz to 3200 Hz.

Calibration can be performed manually at a flow rate of 0.5 L/min or remotely at 2.0 L/min, with initial sensitivity > 15 mV/%LEL. The sensor remains accurate under a wide range of environmental conditions, with temperature shift ≤ ±5% LEL from -40 ºC to +200 ºC and humidity effect < ±5% LEL from 10% to 90% RH. The 350800-01-180-00 ensures precise gas monitoring for critical industrial and hazardous applications.
