AST4600 and AST46HA Series explosionproof pressure transmitters

The AST4600 and AST46HA Series explosionproof pressure transmitters are now available in new materials and with new pressure ranges and options. The expanded pressure range of 0–2.5 psi to 20,000 psi addresses the need for high- pressure transmitters capable of withstanding cycling; a vented gauge reference allows for use at low pressures. A failure-mode indicator option provides better system control in the event of sensor failure. F250C female process ports allow robust high-pressure connections. Construction of Waspalloy (a nickel-based alloy) makes the transmitters suitable for use in the processing of heavy oil and high sulfidation. Class 1, Div. 1, Groups A, B, C, and D approvals for the AST46HA allow the transmitter to be used in acetylene and hydrogen environments. Sealed gauge versions are approved for Class 2, Div. 1 Groups A, B, C, and D mining applications.
