3160 - Trace oxygen analyzer - Teledyne Analytical Instruments

Introduction 1Introduction1.1 Features1.1.1 Fixed FeaturesThe Model 3160 is a microprocessor-based trace oxygen monitoring system thatprovides on-line monitoring of trace oxygen at parts-per-million (PPM) levels and candirectly measure the level of purity in high-grade gases.The 3160 computer uses an Intel ® 80188 microprocessor combined with 32kilobytes of random access memory (RAM) and 128 kilobytes of read-only memory(ROM). The total computer program resides in the ROM and is not affected by shutdownperiods, loss of power, or battery failure. However, calibration parameters andstored measurement readings are retained in battery-backed-up RAM, which requirecontinuous battery voltage in order to be retained. This information will be lost ifbattery power is interrupted, as in battery replacement.Two displays help you monitor trace oxygen levels: a red 4-digit light emittingdiode (LED) display with one-inch numerals is easily read at a distance or even inbright daylight, and a liquid crystal display (LCD) helps you keep track of alarmsetpoints, ranges, mode and system statistics.1.1.2 Variable FeaturesVarious models are available. The following features describe the basic model,but the exact configuration depends on the standard options incorporated. Paragraph1.3 contains a list of standard variations on the basic model.The Class B-2 Micro-Fuel Cell measures trace O 2in a mixture of gases. Becausethe Micro-Fuel Cell sensor is a sealed electrochemical device, it is replaced as a unit.There are no electrolytes to change or electrodes to clean, making the sensor maintenancefree. The analyzer can be configured with one or two sensor blocks. Each blockcan be isolated by pneumatically switched valves. The software automatically adjustswhen a second cell block is present.TELEDYNE ANALYTICAL INSTRUMENTS1-1
