1.0 PURPOSE AND SCOPE

1.1 Purpose

This procedure provides a safe and uniform method for calibrating Foxboro Differential

Pressure Pneumatic Transmitters, Series 13, 13A, 13H and 15.

1.2 Scope

This procedure applies to calibrating Foxboro Differential Pressure Pneumatic

Transmitters, Series 13, 13A, 13H and 15.

2.0 INFORMATION

2.1 General Information

2.1.1 If performance of any steps in this procedure is not required for procedure

completion, indicate steps not performed by entering "N/A" in appropriate

Data Sheet signoff space and explain in COMMENTS/REMARKS section of

Data Sheet.

2.1.2 Calibration is required if the following has occurred:

The unit has been taken apart for cleaning or parts replacement

The range has been changed

The amount of elevation or depression has been changed

substantially.

2.1.3 The transmitter may be calibrated either to the English (psi) or to the metric

(Kg per sq cm) signal pressure range. The two ranges are not exactly

equivalent; therefore, the transmitter must be calibrated to the same signal

pressure range as the receiver with which it is used.

3.0 PRECAUTIONS AND LIMITATIONS

3.1 Radiation and Contamination Control

3.1.1 Work in radiological areas will be performed using a Radiological Work

Permit following review by Radiological Control per ALARA work planning

procedure TFC-ESHQ-RP_RWP-C-03.

3.1.2 When disconnecting equipment from potentially contaminated systems or

breaking open potentially contaminated lines:

Continuous HPT coverage is required

A damp rag will be used to contain the breach until radiological

verifications have been performed

Special care shall be taken to ensure contamination control is

maintained.

3.1.3 When work is performed in or when work will result in a high contamination,

high radiation, or an airborne radioactivity area, then an approved work

package must be developed which is reviewed by Radiological Control per

the ALARA Work Planning Procedure TFC-ESHQ-RP_RWP-C-03,

(ALARA Work Planning). Any changes in the work package or this

procedure that affects radiological aspects of the work must be approved by

the appropriate project Radiological Control Organization.

3.2 Environmental Compliance

3.2.1 When working on potentially contaminated ventilation systems/equipment:

Equipment with removable contamination and/or work with

removable contamination will be contained per the latest revision of

the Containment Selection guide, Attachment A, in TFC-ESHQ-

RP_RWP-C-02

Pre and post job surveys (smears) shall be taken.

Attachment 2 – Calibration Instruction

Positive pressure calibrations:

Note: Vent Valve assembly is required on all positive pressure calibrations to ensure MT&E is not

contaminated by venting potential process air back through MT&E.

Install vent valve assembly Per Figure 5

Ensure IV is open and VV is closed

Proceed with calibration per work package

Whenever venting is required during calibration steps, vent stored pressure as follows.

NOTE- Valve IV can remain open when reading is required via M&TE.

Ensure IV valve is closed

Ensure VV valve is opened

Repeat sequence as necessary to complete the calibration.

After all steps are completed for the calibration, perform RCT survey release plan XXX

Negative pressure calibrations:

Note: use of surrogate filter is required for negative pressure calibrations to ensure MT&E is not

contaminated by pulling process air into MT&E while drawing Vacuum.

Negative calibrations should be performed as Follows.

Ensure surrogate filter holder has media installed.

Connect filter in-line per Figure 4

Ensure IV is open

Pull a representative vacuum into MT&E through filter

Ensure IV is closed

Vent through VV

RCT to perform survey of the media.

IF no contamination found remove surrogate filter holder/manifold and proceed with calibration.
