AST4310

Field Adjustable Pressure Sensor - Class 1 Div 2 Groups A, B, C, D Non-Incendive Media Isolated Stainless Steel

AST4310 Class 1 Div 2 Non-incedive Adjustable Pressure Transmitter with Single Seal product photo

While AST's Krystal Bond Technology offers low operating strain (minimal movement of the diaphragm measuring the pressure), certain applications require the ability to adjust the zero and span readings to ensure precise calibration in the field. The AST4310 is a media isolated, Non-Incendive field adjustable pressure transmitter suitable for use in hazardous areas. 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 AST4310 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 AST4310 is the solution for pressure measurement when adjust ability is necessary. The AST4310 is also now available with CSA Single Seal Approval.
