PROXIMITY PROBES-FORWARD The following design data and technical specifications are required for a contract to supply eddy-current proximity transducers (probes), probe drivers (oscillator-demodulators), associated cable, and probe driver housings for Hydroelectric Units 1 - 3 at Boise Diversion Powerplant, Snake River Area Office. These three hydro units, which are currently being rehabilitated, have fluid film guide and thrust bearings and operate at a speed of 240 rpm (4 Hz). At the present time we plan on installing the proximity probes for commissioning the re-furbished units and for future monitoring. We do not plan on purchasing a full monitoring system at this time, but will use a temporary portable system, connected to these probes, to collect shaft run-out data during the start-up and testing of the units. The probes will be permanently installed and in the future we may purchase a full system, compatible with these probes. After commissioning, they will continue to provide critical data for rough zone operation, as well as indicating bearing wear and clearances, and general operating condition of the rotating machinery. The mechanical monitoring will include measuring radial shaft vibration (run-out) and orbits at three guide bearings, two of which are water-lubricated and are submerged under water. The unit shafts are constructed of forged steel. The proximity probes will be used as follows per hydrogenerator unit: 3 pairs used as X-Y dual vibration transducers located at the lower turbine guide bearing, the upper turbine guide bearing, and the lower generator guide bearing of each unit. We will install two probes at each bearing location, for a total of six per unit. The two probes mounted on the bottom bearing will require 12 meters of un-interrupted cable, directly connected to the probes for submerged operation. This is not a normal industry standard. For the two probes at the middle guide bearing, the industry-standard, 9 meter cable length, will be sufficient, but the cable will also need to be un-interrupted for submerged operation. This, also, is not a normal industry standard. The two probes at the upper guide bearing will be in a dry location, and may use the industry-standard 9-meter cable system. SECTION A - DESCRIPTION/SPECIFICATIONS SUBSECTION A.1 - GENERAL REQUIREMENTS A.1.1 This specification describes transducers for the measurement of shaft displacement, run-out, and orbits on vertical hydroelectric generating units. This transducer equipment is to be furnished by the Contractor. The equipment is to be installed by government forces at Boise Diversion Powerplant, Snake River Area Office. A.1.2 Submittal Requirements Three complete sets of manuals describing the installation, operation, and maintenance of the transducers shall be .furnished by the contractor after award. These manuals shall include parts lists and drawings of the transducer components along with wiring diagrams of the systems electrical equipment. These instructions and manuals will be supplied within two weeks after the award. SUBSECTION A.2 - MATERIALS A.2.1 Work and Materials to be Furnished by the Contractor The Contractor shall furnish eddy-current proximity transducers as specified below. The vibration monitoring equipment consists of the items specified in Section A.3. The locations and quantity required are listed below. A.2.2 General description of equipment supplied by contractor The shaft vibration monitoring transducers, supplied by the contractor, will consist of 20 eddy-current proximity probes with leads and extension cables, and 20 probe drivers (oscillator-demodulators). The contractor shall supply cable to connect the proximity probes to the probe drivers. To provide for the conditions outlined above, the following shall be provided: Group 1: 8 probes (6 plus 2 spares) shall be provided with the industry standard cable leads and extension cables, providing a total electrical length of 9 meters. Lead length may be .5 or 1 meter, and the extension cable shall make up the balance of total length. Group 2: 6 probes shall be provided with a total electrical length of 9 meters, with a water-tight no-connector construction, suitable for submerged operation. Group 3: 6 probes shall be provided with a total electrical length of 12 meters, with a water-tight, no-connector construction, suitable for submerged operation. The government will supply three - conductor, 18-20 ga. shielded cable to provide power to and carry the signal from the proximity probe driver to the government-supplied monitoring system. SUBSECTION A.3 - TRANSDUCER EQUIPMENT TECHNICAL REQUIREMENTS A.3.1 Proximity probes, leads, extension cables, and drivers. 20 displacement transducers consisting of proximity probes, leads, extension cables, and oscillator-demodulators (probe drivers), shall be supplied as described below: (1) The probes shall be of the non-contact, proximity, eddy-current type with a case length of 2 inches, a probe tip diameter of 8 mm, and with a total system electrical length as describe above in section A.2.2. The probe tip shall be manufactured of a high strength, heat and chemical resistant plastic such as polyphenylene sulfide(PPS), and shall be mounted in a stainless steel case. The probe shall have an 80 mil linear range or greater, ranging from 10 mil to 90 mils (+/- mil) from probe tip, and shall have a minimum frequency response of 0 to 100 Hz (0 to 6,000 cpm) calibrated for a steel shaft.. The probe and lead shall be rated overall to operate between 0EC and 100EC. A connector isolator consisting of shrink tubing shall be provided to cover and isolate all mated connectors, where applicable. All probes furnished are to be of the same dimensions. The probe mounting shall have a 3/8" X 24 UNF-2A thread the entire length of the stainless steel case and the cable-end connector shall be compatible with the extension cables. (2) The oscillator-demodulators (probe drivers) shall be capable of at least an 80-mil linear range starting at 10 mils from probe tip to measured surface, and must be temperature stable over at least 0EC to 100EC. Output incremental scale factor shall be 200mV/mil unless otherwise approved by the government. These probe-drivers are to work with the probe described in (1) above using ferrous(steel) target material. These probe-drivers must be compatible with the probes. The probe-drivers are to be supplied unmounted, with all necessary hardware to adequately mount each probe driver and electrically connect to the probes. The probe drivers shall be electrically isolated and the input shall consist of a female coaxial connector and an output consisting of leads for a three wire conductor (power, common, and output signal).
