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.



• Lightweight, compact and all-welded rugged stainless steel construction
• Thin-film & diffused silicon sensors for high accuracy
• Optional HART® communication protocol with diagnostics & field calibration,reducing maintenance time and cost; and 10:1 turndown ratio for re-ranging, maintaining high accuracy and allowing one part number for multiple pressure ranges
• High accuracy (±0.1% and 0.25% FSO, LHR)
• cULus Certification for Ordinary Locations
• IP66 & IP67 and NEMA 4X Protection
• CE, CRN, NACE compliant and Superior EMC/EMI protection
• RoHS / REACH Compliant



• Production Control Systems
• Chemical Injection Systems
• Oil & gas pipelines
• Petrochemical plants
