DESCRIPTION OF REQUIREMENTS
Background
The Engineering Laboratory at the National Institute of Standards and Technology (NIST) is currently enhancing its structural testing capabilities by outfitting the structural testing laboratory in Building 226 with new measurement capabilities. Structural testing will include, among others, testing of steel and reinforced concrete beams, columns, and reinforced concrete shear walls. In order to obtain the requisite experimental data, displacement transducers will be required to measure the deformations of specimens during testing.
Objectives
The purpose of this acquisition is to procure fifty-six (56) Linear Variable Differential Transformers (LVDTs). These instruments will be used to measure structural displacements during testing of structures.
Required Specifications
The Contractor shall provide a total of fifty-six (56) LVDTs in accordance with the following specifications:
- LDVTs shall be provided in the quantities and stroke ranges identified below:
Quantity of LVDTs Stroke Range (in)
Twelve (12) 0.5
Twenty-four (24) 1.0
Twenty (20) 2.0
- All LVDTs shall operate on a 10 Volt single-ended DC power supply
- Input current shall be less than 20 mA at 10 V DC input for all LVDTs.
- All LVDTs shall be internally regulated and thus allow operation from unregulated power source.
- All LVDTs shall provide either a unipolar output signal with a span of at least of 5V DC from one end of the working range to the other, OR a bipolar output signal reading 0V DC in the null position and at least ±2.5 V DC at either end of the working range.
- The nonlinearity of each LVDT shall not exceed ±0.25 % of the full range (FR) of the stroke.
- Output ripple and noise of each LVDT shall not exceed 10 mV (RMS).
- Each gage shall be factory calibrated and furnished with certification and calibration data.
- All LVDTs shall be suitable for operating temperature ranges of at least 0 to 85 °C.
- All LVDTs shall have stainless steel housing.
- All LVDTs shall include cables which are jacketed and shielded.
- Each LVDT provided to NIST shall include coil body, core with threaded ends, and core connecting threaded rod with a sufficient length so that the rod protrudes from the coil body a minimum of 1 inch at the null position when the LVDT is assembled.
Warranty
LVDTs shall be warranted as free of defective materials and faulty workmanship for a one-year period after delivery.
Delivery
The LVDTs shall be delivered no later than 60 days after contract award. Delivery shall be made FOB Destination. Products must be delivered with a certificate of calibration, inclusive of calibration method description.
The Contractor shall deliver the fifty-six (56) LVDTs specified above to the NIST to 100 Bureau Drive, Stop 861, Gaithersburg, MD 20899-8611.
Installation
There is no requirement for installation of the LVDTs.
Testing and Acceptance
Upon receipt of the LVDTs, NIST will test the LVDTs in accordance with the ASTM E2309-16 Standard with 10 V DC excitation, and the results will be used to verify the manufacturer-provided calibration values.
Acceptable performance will be the verification of the manufacturer-provided calibration values with relative errors of less than 0.5 % and fixed errors of less than 0.001 in.
PERIOD OF PERFORMANCE
The period of performance shall be 60 days from date of award.
PAYMENT TERMS
One lump sum payment will be authorized upon the successful testing and acceptance of the Contractor's delivered products.
APPLICABLE PROVISIONS AND CLAUSES
Please see the attached document for applicable provisions and clauses.
