Barksdale Intelligent Transmitters (BiT), Series 450 is a high pressure transmitter with HART® communication protocol option. HART® enabled sensors can communicate over the legacy two-wire 4-20 mA analog current loops offering smart features like transmitter diagnostics, calibration, and field re-ranging up to 10 times less than calibrated full scale output (10:1 turndown ratio). Three models are available: Series H455, 4-20 mA output with HART® Comm. Protocol; Series 455, 4-20 mA output; Series 452, 1-5 VDC output. These models can be configured with 24-standard pressure ranges from vacuum to 30,000 psi and multiple process connections from 1/4” NPT to 7/16” SAE and HF4 Autoclave high-pressure connections. Multiple electrical connections are also offered, including popular industrial and MS style connectors for easy connection. Series 450 offers cULus approval for ordinary location.General Specifications*Accuracyincluding Linearity,Hysteresis and Repeatability:at 75°F, Typical±0.1% of Calibrated FSO (Option [–A1])±0.25% of Calibrated FSO (Standard)±0.5% 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 7500 psi models1.5X range for 7500 - 30000 psi modelsInput:H455:455*:452*:Excitation voltage: 9 to 30 VDCExcitation voltage: 9 to 30 VDCExcitation voltage: 12 to 30 VDC* (SELV, PELV), Class II Power SupplySupply Current:H455 & 455:452:20mA max.20mA max.Output:H455:455:452: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%Output: 1–5 VDCFull scale output: 5.0 VDC ± 1%Zero output: 1.0 VDC ± 1%DynamicResponse Time:H455:455 & 452:<70 milliseconds<50 millisecondsEnclosure:All welded 300 series stainless steel.
