_ PURPOSE The purpose of this procedure is to provide instructions for calibration of Diesel Generator Calcon Pneumatic Temperature Sensors.
2.0 PRECAUTIONS AND LIMITATIONS 2.1 All steps in this procedure are to be performed in sequence except as noted.
[]
2.2
- Performance of procedure step, as identified by a double asterisk (*/*),
shall be initialed on
" Checklist" except when recording data on Data Sheet.()
2.3 To minimize entry of foreign material into the pneucaric portion of sensor DO NOT remove the Tubing fitting.
If sensor is being replaced or if a new fitting is required follow the cleaning procedure for sensor.
(Per Section 4.4)
()
2.4 Any calculations necessary for the performance of this
(
procedure shall be shown on " Calculation Sheet".
(1 2.5 If, during performance of this procedure, any of the following occur, immediately notify I&C Foreman.
2.5.1 Any personnel error, procedure inadeauccy, or malfunction is identified which could prevent fulfillment of " Acceptance Criteria".
(1 2.5.2 Any test exceeds specified limits.
()
2.6 This procedure may be performed in any plant operational mode.
[]
3.0 PREREOUISITES OR INITIAL CONDITIONS 3.1 Notify Shift Suaervisor, or designee, of work to be
- /*
performed and obtain signature authoritation.
()
3.2 Netify Reactor Operator (RO) that instruments
- /*
associated with sensor may be erratic or inoperable
~ ~ ~ ~
during performance of this procedure and obtain RO signature.

4.2.2 Determine if the spacer-tube is loose, if loose perform the following:
4.2.2.1 Unscrew spacer-tube completely.
()
4.2.2.2 Apply Loetite-290 to threaded joint.

4.2.3 Place temperature sensor (in thermowell and hand tighten set screw) into temperature bath a sinimum of three inches.
[]
4.2.4 Connect test equipment to temperature sensor and 60 pai as shown in Figure 1.
()
4.2.5 Vibrator should run,15-30 cycles per second, 5-15 mils displacement during the actual calibration.
Vibrator does not need to run during the soak period.
[]
4.3 CALIBRATION 4.3.1 INCREASE temperature bath at a rate of 2'F per minute to a point at which sensor just starts to vent or 165'F is reached.
Hold temperature bath at this temperature for two hours to allow temperature sensor to s tabilize.
()
NOTES a.
As setpoint is approached temperature bath should be adjusted in r aller increments, allowing temperature to stabilize after each adjustment and prior to obtaining data and sensor conditions.
b.
The sensor is considered tripped when the decreasing l
60 psig signal reaches the 20 psig mark.
