Series 450
- Lightweight, compact and all-welded rugged stainless steel construction
- High performance 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, (L,H,R)
- cULus Certification for Ordinary Locations
- IP66 & IP67 and NEMA 4X Protection
- CE, CRN, NACE compliant and Superior EMC/EMI protection
- RoHS / REACH Compliant
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.
