Ashcroft 2279 Duratran Gauge and Transmitter

Duratran Gauge and Transmitter
2279

The Duratran® solution is a reliable Duragauge® pressure gauge fitted with optical circuitry to provide a 4-20mA output. The 4-1/2" phenolic case is hermetically sealed, chemical and heat resistant. The wide selection of system materials and corrosion-proof housing meets a variety of demanding applications . . . even those with vibration and pulsation. This transmitter/gauge allows you to save money, replacing two instruments with one Duratran.

Duratran® Transmitter/Gauge, takes the place of an electronic transmitter and a mechanical gauge
• FM approved to 10,000 psi
• 4-20mA, 2 wire output
• Zero and span adjustments
• 4-1⁄2˝ solid-front phenolic case
• Accuracy: ±0.5% full scale including linearity, hysteresis and repeatability

New Duratran®PLUS! Option: 
• Liquid-filled performance in a dry gauge 
• Fights vibration and pulsations without liquid filled headaches 
• See page 10 for details 
• Order as option XLL 

The result is reliable, local, analog pressure indication with an economical transmitter . . . A niche solution for any facility.
