Barksdale 450E (B?T) Series Intelligent Proof Transmitter

Barksdale Intelligent Transmitters (BiT), Series 450E and H450E are BiT's Intrinsically Safe models. Barksdale has been manufacturing explosion proof transmitters for many years allowing their use in Class I Div 1 or Zone 0, 1 hazardous location. So why introduce an Intrinsically Safe (I.S.) model?  Explosion proof wiring requires metal conduit and special explosion proof sealing glands and junction boxes which are not practical for equipment that needs to be quickly rigged or broken down to modular sections to transport on roads to the next location such as Drilling, Frac or other mobile equipment. I.S. protection concept allows use in the same hazardous areas as explosion proof only with the same flexible cables and electrical connections used in ordinary locations including industrial and military style connectors used on our BiT 450 ordinary location models. Maintenance of systems is greatly simplified with quick electrical disconnects and no expensive explosion proof boxes that are susceptible to scratches on sealing flame path surfaces during maintenance. Barksdale’s new intrinsically safe models also include advanced Thin-Film and HART technology providing all of the advantages of our other models including high accuracy and long term stability.General Specifications*Accuracy (LH & R):at 75°F, Typical±0.10% of Calibrated FSO (Option [–A1])±0.25% of Calibrated FSO (Standard)±0.50% of Calibrated FSO (Vacuum only[-23])Temperature Shift:Zero & Span: 0.0125% Per °F over the compensated temperature rangeLong TermStability:closure rating:±0.2% FSO /year of calibration curveTypical Life Cycle:100 million cyclesProof Pressure:2X range for up to 7,500 psi models1.5X range for 7,500 - 30,000 psi modelsInput:Excitation voltage: 9 to 30 VDCSupply Current:20mA max.Output:H455E:455E:Output: 4–20 mA with HART® ProtocolFull Scale Output: 20 mA ±1%Zero output: 4 mA ±1%Output: 4–20 mAFull Scale Output: 20 mA ±1%Zero output: 4 mA ± 1%DynamicResponse Time:Enclosure:All welded 300 series stainless steel.
