Barksdale 423H-04 Pressure Transmitter

The Barksdale 423H-04 Pressure Transmitter is a rugged, explosion-proof pressure transducer in Barksdale’s Series 423X family, engineered for harsh industrial settings where hazardous atmospheres are a concern. The 423X-04 base model provides a 0.5–5.5 VDC analog output (not ATEX approved), with gauge pressure as the standard configuration and absolute pressure available via the -A option. Available pressure ranges span from vacuum (0–29.9 inHg) up to 150 psi (0–10.3 bar), with sub-ranges such as 0–5 psi, 0–15 psi, 0–50 psi, 0–100 psi, and 0–150 psi depending on the code. The Series 423X family also includes variants like 4–20 mA outputs on the 425X and 1–11 V outputs on the 426X, offering flexibility for different instrumentation and control architectures in industrial environments. These devices are designed for use in process monitoring, hydraulic systems, and other demanding applications where reliable, explosion-protected sensing is essential.
