Common use of Transmitters Clause in Contracts

Transmitters. Transmitters shall be 4-20 mA dc two-wire, solid-state type, with plug-in circuit board. External zero and span adjustments are required. All parts of the transmitter in contact with the process medium shall be constructed of materials suitable for the application and the pressure-temperature conditions encountered. Transmitters utilized for measuring differential pressure, flow, and level shall be furnished with a preassembled valve manifold suitable for mounting directly on the transmitter. All transmitters shall be designed to prevent the process medium from contacting the electronics or from entering the wiring circuit if the measuring element fails. 0.1 percent or better. Each transmitter shall have an integral junction box with terminal strip, integral test jacks, and conduit connection, and shall be complete with all mounting accessories. When transmitters are required to provide multiple outputs to recorders, indicators, etc, as well as providing an input to the control system, the circuit shall be arranged so that disconnecting an input to a recorder, indicator, etc, shall not cause an upset in the control system, or a change in transmitter calibration. -------------------------------------------------------------------------------- EPC - Exhibit B -------------------- TENASKA GEORGIA GENERATION PROJECT Page 125 of 132 -------------------------------------------------------------------------------- It shall be possible to ground either output terminal of a transmitter or its receiver without affecting transmitter characteristics. There shall be no signal grounds within the transmitters. Reservoirs shall be furnished by the Contractor when required by the service or type of transmitter supplied.
