About this file

This document is a Non-Competitive Procurement Justification Memo from the Naval Surface Warfare Center Carderock Division (NSWCCD) for a specialized Validyne Engineering pressure transducer sensor setup. The procurement seeks to purchase multiple components including 18 analog output signal sensors, 20 sensor/demodulator end connectors, 2 multi-slot module cases, 20 card demodulator plug-ins, 72 replacement diaphragms of varying pressures, and 36 replacement O-rings, with a required delivery date of 9/17/25.

The justification for sole-source procurement is based on compatibility with existing Validyne hardware in the Large Cavitation Tunnel, which has restrictive licenses and requires specific proprietary equipment. The memo cites that the new sensors will extend current sensor measurement capabilities, add input channels, and improve measurement accuracy for hydrodynamic flow characteristics. The total procurement is from Validyne Engineering in Canoga Park, California, and is being processed under Federal Acquisition Regulation (FAR) provisions for non-competitive purchasing under the simplified acquisition threshold.

NSWCCD SAP Non-Competitive Procurement Justification Memo Effective April 2025

MEMORANDUM FOR FILE

FROM:

CODE: 8530

TO: Code 02 SUBJECT: Non-Competitive Procurement Justification Memo for Actions Under SAT

I. BACKGROUND

1. FAR 13.106-1(b)(1)(i) states for purchases not exceeding the simplified acquisition threshold, Contracting Officers may solicit from one source if the Contracting Officer determines that the circumstances of the contract action deem only one source reasonably available.

2. FAR 8.405-6 allows for limiting sources for orders or BPAs under Federal Supply Schedules under certain circumstances or for items peculiar to one manufacturer

3. As required by FAR 13.106-3(b)(3)(i), FAR 8.405-6(a)(1), or FAR 8.405-6(b)(2), this memorandum explains the absence of competition for this acquisition, as only one source will be solicited for this requirement (or for a portion of the requirement) and the requirement is not expected to exceed the simplified acquisition threshold.

II. DESCRIPTION OF ITEM OR SERVICE (Include manufacture/sole source name and address.)

New pressure transducer sensor setup will be used to extend current sensor measurement capabilities from existing equipment. The purchase will add sensor input channels and these sensors promote higher measurement accuracy. Improved measurement accuracy will help resolve hydrodynamic flow characteristics.

Items are required for purchasing.

1. Analog Output Signal:+/-10Vdc, Diaphragm Accuracy:0.25% FS, Sensor Electrical Connector: PT02A- 10-6P, O-ring: BUNA- -27 NPTF Female with 8-port, Factory calibrated sensor with diaphragm 30 (1.25 psi), Item Number DP15-30-2695 Quantity: 18

2. Sensor/Demodulator End Connectors: PT06A-10-6S mating connectors (must connect DP15 PT02A-10- 6P to demodulator unit), Belden 8723 - 22 AWG stranded (7x30) tinned copper conductors, polypropylene insulation, twisted pairs, individually shielded(100% coverage), 24 AWG stranded tinned copper drain wire, PVC jacket, Length: 75 feet, Item Number 12457-75 Quantity: 20

3. Multi-slot Module Case Card Slots/Channels:10, Input/Output Connections: PT02A/XLR, Power Requirements: 105-125VAC @ 50 -400Hz, Item Number MC1-10-P-1A Quantity: 2

4. Card Demodulator Plug-ins Carrier Supply: Voltage -5Vms Sine Wave, Frequency-3kHz, Power Available-5VA(Maximum), Carrier Regulation: Line- Amplitude +/-0.05% & Frequency +/-0.01%, Load- Amplitude +/-0.15% & Frequency +/-0.10%, Temp- Amplitude +/-0.01% & Frequency +/-0.006%, Item Number CD19A-1-A-1-A-1 Quantity: 20

5. Replacement Diaphragms:1.25psi with 0.25% accuracy, Item Number 3-30 Quantity: 36

6. Replacement Diaphragms:2.0psi with 0.25% accuracy, Item Number 3-32 Quantity: 36

NSWCCD SAP Non-Competitive Procurement Justification Memo Effective April 2025

7. Replacement Diaphragms:5.0psi with 0.25% accuracy, Item Number 3-36 Quantity: 18

8. Replacement Buna O-ring: BUNA-N O-rings for DP15-30-2695, Item Number 2773-0224 Quantity: 36

Manufacturer: VALIDYNE ENGINEERING Address: 21019 Osborne St, Canoga Park, CA 91304 Phone: 818-886-8488 x 700 POC: manish@validyne.com

Required Delivery: 9/17/25

III. BASIS FOR DETERMINATION FOR USE OF OTHER THAN FULL & OPEN COMPETITION

A. BRAND NAME. The item required must be a brand name product, or feature of a product, particular to one manufacturer.

The existing Validyne pressure transducer setup requires additional sensors and data acquisition hardware for flow measurements in the Large Cavitation Tunnel which has a very large cross-sectional area, approximately ransducers and hardware which has restrictive licenses. Items required for purchase must be compatible with existing Validyne sensors and hardware equipment.

1. Restrictive Rights. The source has established proprietary rights, limited rights in data, patent rights, copyrights, or secret processes in the item or service required.

Validyne sensors and hardware are compatible with current pressure measurement setup. The additional equipment setup provides a simple plug-in and measure solution reducing downtime. Validyne pressure transducers and hardware which has restrictive licenses.

2. Exclusive Licensing Agreements. The item or service is only available from the Original Equipment Manufacturer (OEM).

3. Federal Supply Schedule (FSS) IAW FAR 8.405-6(b).

4. Other Reasons.

B. SOLE SOURCE. (select all that apply)

1. Restrictive Rights. The source has established proprietary rights, limited rights in data, patent rights, copyrights, or secret processes in the item or service required.

2. Exclusive Licensing Agreements. The item or service is only available from the Original Equipment Manufacturer (OEM), or there is only one authorized distributor or technical representative for the OEM.

3. Other Reasons.
