AST4410

Field Adjustable Intrinsically Safe Pressure Transmitter - Class 1 Div 1 IS Groups C, D with Approved Barrier - Stainless Steel Media Isolated

AST4410 Class 1 Div 1 Intrinsically Safe Adjustable Pressure Transmitter with Single Seal product photo

The AST4410 is a media isolated, field adjustable pressure transmitter suitable for use in Class I Div 1, Groups C, D Intrinsically Safe areas when installed with an approved barrier. Protected by a Viton O-ring, this transmitter’s two potentiometers have the ability to adjust the zero and span output signals up to ± 5% [of the full scale pressure]. Additionally, the AST4410 offers access points through the housing of the transmitter in order to simplify adjustments after installation. Complete with a wide range of threads, pressure ranges and output signals, the AST4410 is the solution for pressure measurement when field adjustability is necessary. The AST4410 is also now available with CSA Single Seal Approval.
