The Millennium WS is a complete self contained optical hydrocarbon gas detector. The sensing and reference elements are self-compensating for optical integrity and other signal inhibitors. The industry standard 4-20 mA analog output provides remote alarm, fault and calibration signals. Applications Refineries Drilling and production platforms Fuel loading facilities Oil well logging LNG/LPG processing and storage facilities Gas turbines Chemical plants Compressor stations Wastewater treatment facilities Transportation facilities Features Reliable infrared sensing technology Virtually maintenance free Low cost of ownership, over five years operating life Immune to poisoning and etching Designed for harsh environments Explosion proof Fast response time Rugged stainless steel construction Smart calibration Patented self compensating optical bench and no moving parts Heated optical chamber Low power consumption Operates in constant hydrocarbon background and anaerobic atmosphere Fault indications for all failure states Routine calibrations are not required 4-20 mA output 0 to 100% LFL detection range Can be coupled with SEC 3100 transmitter for network applications RS-485 communication link Digital display optional Specifications Detectable Gases Acetone, DF 2000, Green Earth Range 0-100% LFL Accuracy ±3% to 50% LFL or ±5% 51 to 100% LFL Detection Method Diffusion, optional sample draw, requires a minimum of 1 LPM flow rate Power Consumption 5 watts Analog Output 4-20 mA, max 1000 Ohm load at 24 VDC supply voltage Response Time T50 < 5 seconds, T90 < 10 seconds Operating Temperature -40 to 70°C, 0-99% RH, non condensing Operating Range 18 to 32 VDC measured at detector head Max Current Draw At 24 VDC: Average 210 mA, Peak 400 mA Construction 316 stainless steel Classification Class I, Div I, Groups B, C, D Approvals C 22.2 No. 152-M1984 (R1997) Installation Category Cat I, Pollution Degree 2 Weight 5 pounds Unit Status Chart Current Output Status 4-20 mA Normal measuring mode 0.0 mA Unit fault 0.2 mA Reference channel fault 0.4 mA Analytical channel fault 0.8 mA Unit warm up 1.0 mA Optics fault 1.2 mA Zero drift fault 1.6 mA Calibration fault 2.0 mA Unit spanning 2.2 mA Unit zeroing 4.0 mA Zero gas level 5.6 mA 10% of full scale 8.0 mA 25% of full scale 12 mA 50% of full scale 16 mA 75% of full scale 20 mA 100% of full scale 20.1-23 mA Over range (>100%) Ordering Information For pricing, please call AFC International at 1-800-952-3293, 219-987-6825 or fax 219-987-6826 or email firstname.lastname@example.org Description Catalog No. SEC Millennium Infrared Hydrogen Gas Detector for Acetone 49002300100L012 SEC Millennium Infrared Hydrogen Gas Detector for DF 20000 490020001000L012 SEC Millennium Infrared Hydrogen Gas Detector for Green Earth 49002100100L012 Downloads Millennium WS Hydrocarbon Detector literature Product Enquiry Name Email address Enquiry Related products SEC 3120 Digital Gas Transmitter Dual Sensor Ships directly from the manufacturer, shipping times may vary.
