Field Instruments Sample Clauses
Field Instruments. Each RTU is connected to field sensors that provide indication of the process conditions into the PLC system. Typical analog sensors used in the City’s system include pressure, level, flow, temperature and analytical – each of which that provides a signal that is a percentage of the maximum allowed/measureable. Discrete signals are also measured including door ajar, smoke, flood, and other float type indications. These sensors exist in the City’s system and most are nearing their anticipated life. The Consultant includes a data column in the pricing sheet for replacement of these older field instruments to provide a worse case replacement price, however the City may elect to stock a couple sensors of each type and replace as necessary.
Field Instruments. Discussion of the field instrument maintenance and calibration is included in Section 2.2.3 and SOP SAS- 02-01. The calibration and maintenance instructions follow the manufacturer’s recommendations and directions, which are also a part of SOP SAS-02-01.
Field Instruments. A photoionization detector (PID), flame ionization detector (FID), or portable gas chromatograph (GC) may be used to screen soil samples collected from the sample locations to provide support of laboratory results and field observa- tions. Field instruments may also be used to screen additional locations where the cost of collecting a laboratory sample would be prohibitive. Examples of such locations include changes in soil type and underground utility con- duits. Field instruments may not be used to decrease the number of soil samples that must be laboratory analyzed. Collect and present all field instrument data in accordance with DNR−approved field instrument techniques pro- vided in reference 7. ‘Additional Information Required for Certification’ (located after the references) lists sources for information on field screening techniques and sampling locations.
Field Instruments. A. All instrumentation to be supplied by the Systems Integrator is specified in this section.
B. Wastewater Pump Station Instrumentation (See Drawings):
1 1 Submersible Level Transmitter GP 50 311Z-M351-PN2
Field Instruments. Field instruments not included as part of the process equipment will be installed in the piping or tanks as required. Compressed air connections will be provided for all air actuated devices. Electrical distribution will generally be made using cable tray with conduit drops to each device. Junction boxes may be used in areas of high density controls to minimize cable runs. Multiple conductor cable will be used where feasible. Analog instrument cables will be 300 volt rated, #14 or #16 AWG shielded with foil ▇▇▇▇▇▇▇. Two, four and six conductor cables will be used. Cable assembly will be tray rated.
