        Overview Manuals Applications Interoperability Configuration & Programming Compliance

        Features:

        • The sealed reference allows pressure to be measured independently of local atmospheric variation.
        • A valid absolute-pressure reference and leak-tight process connection are essential when checking zero or calibration.
        • Temperature changes and vacuum-side installation practices must remain within the completed sensor and fill-fluid limits.
        This order identifies an in-line absolute-pressure transmitter with a sealed measurement reference; the physical nameplate governs the exact assembly supplied.

        Its assigned work is absolute-pressure and vacuum-related process measurement. Range 1 provides absolute-pressure measurement from a sealed vacuum reference rather than local atmosphere.

        Before installation, verify the process connection, wetted materials, sensor fill, housing, output, vacuum service, indication, and approvals. Use a suitable absolute reference when validating calibration or low-pressure performance.

        Availability is subject to Apter Power inventory and sourcing confirmation.

        • Measures absolute pressure in vacuum vessels or process systems where atmospheric-reference variation is unacceptable.
        • Supports vapor-pressure or low-absolute-pressure monitoring with a leak-tight in-line process connection.
        • Provides absolute-pressure input for control calculations that require a sealed rather than vented reference.
        • Host communication is proven without changing the primary measurement behavior of the loop.
        • Process hardware integration is verified through drawings, part records, and seal compatibility.
        • A functional test confirms interoperability throughout absolute and vacuum-related measurement.
        • The asset record preserves range values, engineering units, damping, trim status, and failure behavior.
        • Programming begins from a verified hardware identity and an approved reference condition.
        • Changed parameters are validated at the host before this in-line absolute-pressure configuration returns to automatic control.
        • The supplied approval suffix determines the applicable protection method and installation conditions.
        • Pressure components remain within the material and rating scope accepted by the project.
        • Conformance review includes the actual process connection, sensor fill, vacuum practice, and approvals evidence.
        Description
        3051TA1A is an in-line absolute-pressure transmitter with a sealed measurement reference in the Rosemount 3051 range. The complete nameplate is the controlling record for the supplied assembly.

        The installed duty is absolute-pressure and vacuum-related process measurement. It provides the absolute process variable needed by control and monitoring applications that cannot use a vented gauge reference.

        Before replacement, confirm the process connection, wetted materials, sensor fill, housing, output, vacuum service, indication, and approvals. Record the final comparison in the maintenance documentation.

        Technical notes
        3051TA1A calibration requires a valid absolute-pressure reference; atmospheric venting is not a zero reference, and the Range 1 process connection must be confirmed.

        FAQS

        The following is a list of questions commonly asked by our customers. Please contact us if you have a question about our process that is not answered below.
        VIEW ALL FAQS
        Why must 3051TA1A be calibrated against an absolute-pressure reference?
        Its sealed measurement reference requires a known absolute standard; an ordinary vented gauge source cannot establish the correct reference.
        Which vacuum-side installation concern matters for 3051TA1A?
        Confirm leak-tight process connection, compatible wetted materials, vacuum practice, sensor orientation, and the receiving loop.
        In which absolute-pressure duty would 3051TA1A be selected?
        Select it for absolute or vacuum-related duty where the control calculation cannot rely on local atmospheric pressure.
        What calibration scope should accompany a request for 3051TA1A?
        Provide the calibration scope, target units, condition, quantity, destination, delivery requirement, and complete nameplate.
        Why is a gauge transmitter not a functional replacement for 3051TA1A?
        A gauge transmitter uses a different pressure reference and is not functionally equivalent without redesigning the measurement.
        Which data-sheet section confirms the measurement reference for 3051TA1A?
        Review the Rosemount 3051T data sheet and reference manual sections for absolute measurement, mounting, and calibration.
