PURCHASE DESCRIPTION

Measurement Science and Engineering Department

Pneumatic Control Units

1.0 INTRODUCTION

Naval Surface Warfare Center, Corona (NSWCCO) Division, Measurement Science and Engineering Department has a requirement to procure 10 King Nutronics Pneumatic Control Units (PCU), model 3461-2-1. The PCUs are part of the Portable Gas/Hydraulic Pressure Calibration System King Nutronics model 3461-1-1.

2.0 BACKGROUND

The current main model King Nutronics 3461-1-1 includes the PCUs this procurement would replenish existing units to continue Navy support for pressure calibrations.

3.0 SCOPE

The Naval Sea Systems Command (NAVSEA) Metrology and Calibration (METCAL) Program has a requirement for ten (10) PCUs, P/N 3461-2-1.

5. REQUIREMENTS

Pneumatic Control Units model 3461-2-1.

The control unit incorporates the valves, regulators, gauges, and other components necessary to provide test pressures for Instrument calibration.

All components are panel-mounted within an aluminum carrying case.

An automatic pressure relief valve is installed in the case to relieve both positive and negative pressures that may build up.

Quick-disconnect sockets are provided on the control unit panel and on the high-pressure hose for connection of a master gauge and for connection of the control unit to an item under test.

The sockets are positive locking and cannot be disengaged when the system is pressurized above 250 psig.

A two-position range selection valve permits the operator to select the source of pressure for the test circuit.

The low range shuts off the direct line from the supply source and the test circuit obtains pressure from the regulator circuit at the lower, regulated pressure.

The high range applies pressure directly from the supply source to the test control valve.

Calibrations at elevated pressures are accomplished by an integral booster pump with a 10:1 amplification ratio.

Precision metering valves provide fingertip control of calibration pressure throughout the range of 0 to 10,000 psig.

Final, precise adjustments of the static pressure in the test circuit are accomplished by means of a Vernier pressure control. The control contains an automatic relief circuit.

An internal nitrogen cylinder with a storage capacity of 90 cubic inches is contained in the control unit. The internal cylinder permits a substantial quantity of low-pressure calibrations to be performed without use of the external nitrogen supply assembly.

5.1 Logistics Requirements

5.1.1 Warranty. The manufacturer shall provide the minimum commercial warranty for the PCUs of at least one calendar year from date of shipment.

5.1.1.1Warranty Sticker. Each PCU shall have a sticker affixed to the outside of the unit enclosure.

5.1.2 Item Unique Identification (IUID). DFARS clause 252-211.7003 is invoked. A two dimensional Item Unique Identification (IUID) data matrix conforming to MIL- STD-130 shall be included on the identification plate.
