Sensors |
 |
|
Quick Stem Sensor (QSS) |
A patented prefabricated strain sensor that is applied to a valve stem or shaft to obtain a direct measurement of stem thrust and torque without dissassembly of the valve. |
|
|
SmartStem |
Teledyne-patented installation of strain gages on a valve stem or shaft to obtain a calibrated and temperature-compensated measurement of stem thrust and torque. |
|
|
Spring Pack Measurement Device (SPMD) |
A linear position sensor used to measure spring pack displacement to provide an indirect indicator of stem torque and thrust. |
|
|
Motor Voltage Module (MVM) |
Used to measure motor voltages on the 3-phase AC inductive motors typically used on AC MOVs |
|
|
Current Probes |
Used to measure AC and DC current on MOVs. |
|
|
Pressure Sensor Interface (PSI) |
Interface module with six pressure sensors as well as bulkhead connnectors for strain and position inputs. Connects directly to QUIKLOOK II & QLII+ for AOV testing. |
|
|
Stem Postion Indicator (SPI) |
Measures axial stem or rotary shaft travel on both MOV and AOV applications. |
|
|
Rotor Contact Indicator (RCI) |
Provides signal indicating position (open or closed) of contacts on actuator rotor assembly |
|
|
AOV Pressure Sensors |
Pressure sensors of various full scale ranges used in AOV testing |
|
|
MOV Pressure Sensors |
Pressure sensors of various full scale ranges used in MOV testing |
|
|
Systems |
|
|
QUIKLOOK II |
A self-contained “single-box” MOV / AOV valve-testing system used to capture data from any of the sensors noted above or any other strain gage or voltage-based transducer. |
|
|
QL II+ |
A more compact version of the QUIKLOOK II used with a laptop computer. This “two-box” MOV / AOV valve-testing system is used to capture data from any of the sensors noted above or any other strain gage or voltage-based transducer. |
|
|
SENTRY |
Dedicated, permanently-installed MOV / AOV monitoring system |
|
|
Spring Pack Calibration Stand |
The new TTS Spring Pack Calibration Stand (SPCS), when connected to any Teledyne QUIKLOOK system, includes everything needed to calibrate Limitorque spring packs. |
|
|
Software |
|
|
QUIKLOOK II |
MOV / AOV valve-testing software used to acquire, present and analyze data from our QSS and SMARTSTEM sensors or any other strain gage or voltage-based transducer. |
|
|
Spring Pack Calibration Software |
Valve-testing software used to produce a calibration certificate, and to plot generic and calibration data and the sensitivity equation. |
|
|
MOV Design & Test Database Software MIDAS & MIDASTEST) |
MOV design and test databases and calculation engine that automates valve design margin analysis, actuator setup criteria and required test intervals utilizing various ComEd, EPRI, JOG and BWROG methodologies. Includes powerful "what if" margin analysis tool. |
|
|
AOV Design & Test Database Software (ACE & ACETEST) |
AOV design and test databases and calculation engine designed to create AOV setup windows, create an AOV Data Record form for use in valve testing and perform a post-test evaluation of the test results. This program will ensure that the methods used by personnel to perform and document these calculations are consistent. |
|
|
Tools |
|
|
Thread Removal Tool |
Used for the in-situ removal of valve stem threads to permit the installation of our QSS on a smooth stem area for direct, accurate measurement of stem torque and thrust. |
Utilities operating nuclear power plants agree that the correct functioning of all safety-related motor and air-operated valves is of paramount importance. The Nuclear Regulatory Commission issued Generic Letter 89-10 related to this concern, underscoring the need for analysis and periodic testing of these valves to ensure that they will operate when called upon.
