| Low-Power Instrumentation from Moore Industries  Moore Industries' Low-Power Instruments are designed to operate in remote sites in the oil and gas industry, survive harsh environmental conditions, and operate with battery and solar power. Instruments are available for monitoring and controlling temperature, pressure and flow conditions. Typical applications include Coal Bed Methane and natural gas well heads; oil and gas processing, storage and transport; and tank and pipeline cathodic protection. The E/P and I/P converters, temperature sensors, alarm modules, transmitters, data acquisition devices, and signal conditioning instruments have low power requirements that can be supplied by solar cells and batteries.The instruments have ambient temperature specifications of -40°C to +85°C, allowing them to be used in remote sites that have no protection from the weather. Devices that control valves use natural gas instead of instrument air, eliminating the need for a compressor and instrument air source. Low-Power Instruments include: - Models EPX2 voltage-to-pressure and IPX2 current-to-pressure converters can be used to control a valve, using natural gas as the pressure source. Both converters offer output ranges of 3-15, 0-30 and 6-30 psig. The EPX2 takes a 1-5V input, and the IPX2 takes a 4-20mA input. - BIMETAL thermometer provides a local temperature indication via a 3-inch dial gauge and can take temperature measurements with optional RTDs or thermocouple sensors. The RTDs or thermocouples are installed in the thermometer, and connect to a Moore Industries LRX temperature transmitter. - ECA alarm module operates on 12VDC, draws only 5mA maximum, and provides a single transistor output. - LRX temperature transmitter accepts signals from RTDs, thermocouples and mV sources, and produces a 1-5VDC output at 2-3mA, suitable for direct interface with readout instruments, recorders, and data acquisition devices. - NCS computer and data concentrator, a DIN-rail mounted data acquisition device that runs on 12VDC at 500mA, accepts data from temperature, flow, level and pressure sensors and transmitters, and provides a RS232/RS485 MODBUS output to RTUs, wireless modems, and similar devices. - ECT Signal Isolators, Converters, and Repeaters provide isolation and condition, convert, split and boost signals. write your comments about the article :: © 2006 Construction News :: home page |
