What is the Oldham Simtronics GD1-L0P-31KH-0XH-A3?The Oldham Simtronics GD1-L0P-31KH-0XH-A3 is: GD1 System H2S 200 ppm*m, 75m range, ATEX, IECEx, 4-20mA, source, HART. The GD1 is a laser based open path detector for hydrogen sulphide, built as a separate transmitter and receiver. The transmitter emits an infrared laser beam, shaped as a cone rather than a focused pointer beam, and the receiver measures how much light the gas absorbs along the line of sight. The laser diode wavelength is monitored more than 500 times per second so that the absorption line keeps matching the target gas, which is why the detector needs no on-site calibration for its whole life and shows no cross interference from other gases. The laser is Class 1 and eye safe, and both transmitter and receiver have heated optics inside stainless steel housings. The GD1 Open Path Laser Gas Detectors group in the 2026 price book lists 24 orderable part numbers, and ordered against ATEX approval, with the 4-20 mA current source output stage, covering 200 ppm*m.What are the specifications of the GD1 Open Path Laser Gas Detectors?Detection method: near infrared laser scanning with a tunable laser diode, Class 1 eye safeDetected gas: hydrogen sulphide (H2S)Range: 0 to 200 ppm*m default; path length 5 to 75 mAccuracy and repeatability: better than plus or minus 8 ppm*m (under plus or minus 4% of full range)Response time: 5 secondsOutput: 4-20 mA sink or source, factory set, maximum load impedance 500 ohm, with HARTFault signalling: 1 mA fault, 2 mA beam block, optional 3 mA warning; beam block declared above 98% obscurationAlignment tolerance plus or minus 0.3 degrees, with heated optics on both transmitter and receiverSafety Integrity Level 2, with a functional test interval of once per yearCalibration factory set, no field recalibrationWhat should you check before ordering?The GD1 carries a 5 year limited warranty, and it is void if the detector was installed or operated outside the procedures in the operating manual. Alignment is the field risk worth planning for: the laser beam presents a smaller target area than a conventional open path system, so it needs higher alignment accuracy to reach sufficient optical transmission, and poor alignment reduces system performance rather than failing outright. During alignment the 4-20 mA output holds at 2 mA and at power up it holds 1 mA, so a control room seeing those values during commissioning is reading a documented state, not a fault.How do the part numbers differ?The price book lists three orderable forms of the same optical path: a complete System (transmitter and receiver together), a Transmitter on its own, and a Receiver on its own, so a damaged half can be replaced without rebuying the pair.Where is it used?Typical service: Perimeter and fence line hydrogen sulphide monitoring; Open outdoor structures where a single path replaces multiple point detectors; Property boundary monitoring on oil and gas sites; Installations where cross interference from other gases must be excluded.How do I order or get a quote?PE Energy supplies the Oldham Simtronics GD1-L0P-31KH-0XH-A3 on a quote basis: send the part number with your application details and we return pricing and lead time. Fixed gas and flame detection is quoted rather than listed because most references ship configured for target gas, range, approval scope and cable entry, and those choices are fixed at the part number. This part belongs to the same product line as the GD1 laser open path H2S gas detector already in our catalogue.

What is the Oldham Simtronics GD10-P00-03DG-0BH-00?The Oldham Simtronics GD10-P00-03DG-0BH-00 is: GD10P C2H4, Ethylene 100% LEL (2.7%Vol.), SS 316L, CSA, 4-20mA, source. The GD10P and GD10PE are point gas detectors built on non dispersive infrared (NDIR) detection, using a solid state infrared source flashing at 32 Hz across a dual wavelength, dual path optical bench. Because detection is optical rather than chemical, the detector needs no oxygen to measure correctly and works in an inert gas atmosphere, cannot be poisoned by silicon vapours or hydrogen sulphide, is unaffected by gas velocity, and has no saturation effect, so it can read up to 100% volume. Calibration is factory set and no field recalibration is needed. The GD10PE is the version built for critical applications with large volumes of air at high velocity, where low gas concentrations must be caught quickly, such as HVAC and air generator intakes serving inhabited areas and gas turbine installations. The GD10P / GD10PE Point IR Gas Detectors group in the 2026 price book lists 157 orderable part numbers, and this one is the 316L stainless steel build, ordered against CSA approval, with the 4-20 mA current source output stage, covering 100% LEL.What are the specifications of the GD10P / GD10PE Point IR Gas Detectors?Detection method: infrared absorption, dual wavelength, dual path, with a solid state 32 Hz flash IR sourceGases detected: hydrocarbon gases and carbon dioxide; the target gas and scale are fixed by the ordered part numberAccuracy: plus or minus 3% of full scale between 0 and 50% of reading, plus or minus 5% between 50 and 100%Lifetime stability: plus or minus 5% of full scale readingResponse time: T20 0.7 s, T50 1.7 s, T90 4.0 s (fast option: 0.2 s, 0.4 s, 1.0 s)Start-up 65 s typical; 30 minutes warm up to full specification performanceOutput: 4-20 mA current source as standard, current sink as an option, maximum load impedance 500 ohmContinuous self-test, with dirty optics warning at 55% signal attenuation and dirty optics fault at 70%Suitable for use in SIL 2 and SIL 3 systems, with CSA, IECEx, ATEX and INMETRO approvalsGD10PE variant only: detection range 0-20% LEL (0-1% Vol.) methane; the GD10P target gas and scale are fixed by the ordered part numberWhat should you check before ordering?Teledyne guarantees parts and workmanship for 5 years and the infrared sources for 15 years, which is the figure behind the claim of the longest combined detector and IR source warranty on the market. That warranty is void if parts of unspecified origin are fitted, so a spare bought outside the vendor chain can cost the remaining source cover. The practical consequence of the NDIR bench is maintenance cost rather than performance: no chemical reaction means no poisoning by silicon vapours or hydrogen sulphide, and factory calibration means the detector is not on a recalibration schedule the way a catalytic bead point is.How do the part numbers differ?In this part numbering the output stage is selected by one character: H is the 4-20 mA current source version and J is the current sink version. Every complete description in the 2026 price book follows that rule without exception across 107 rows.Where is it used?Typical service: Fixed point combustible gas monitoring in boiler rooms and process areas; Offshore and onshore petrochemical installations; Inert or oxygen-free atmospheres where catalytic sensors cannot measure; HVAC and air generator intakes serving inhabited areas (GD10PE); High temperature areas of gas turbine installations (GD10PE).How do I order or get a quote?PE Energy supplies the Oldham Simtronics GD10-P00-03DG-0BH-00 on a quote basis: send the part number with your application details and we return pricing and lead time. Fixed gas and flame detection is quoted rather than listed because most references ship configured for target gas, range, approval scope and cable entry, and those choices are fixed at the part number. This part belongs to the same product line as the GD10P IR point gas detector already in our catalogue.
