Single-Gas Monitors Boast Long Lifespan
These robust single-gas monitors provide reliable readings under harsh operating conditions. The Pac 6000 and Pac 6500 monitors detect common gases such as carbon monoxide, hydrogen sulfide, sulfur dioxide, and oxygen. The Pac 8000 can also detect less common gases such as ozone, phosgene, and nitrogen dioxide. The Pac 8500 is available with dual sensors for H2S/CO or O2/CO. A hydrogen-compensated carbon monoxide sensor significantly reduces the background noise from hydrogen gas on all models. Users can choose between 18 sensors for the detection of up to 32 different gases. Alarms are issued acoustically, visually, and with a clearly noticeable vibration, and the acknowledged alarms can be accessed later for evaluation. The integrated “D-Light” indicates whether the monitor is functional and ready for operation. In addition to the current gas concentration, the large display provides important information such as remaining battery capacity, target gas, or remaining service life. The industrial battery used in the monitors provides a service life of two years without a battery change. The sensors have an operating temperature range from –40°F to 131°F. An easy-to-replace membrane filter protects the sensor against foreign dust or liquid, and the impact- and chemical-resistant housing meets Ingress Protection (IP) 68 requirements. Each sensor type is identified by a color code to minimize the potential for mix-ups.

Backpressure Regulator Is Self-Operating
The BelGAS CP P5300 backpressure regulator is built in accordance with NACE-MRO175 requirements. Operating between pressures of 15 psi and 300 psi, the regulator has an intermittent-acting pilot and soft-seat material for a bubble-tight shutoff. The regulator is interchangeable with components from other manufacturers. Upstream gas is used to operate the unit, except where liquid or very-low-pressure gas is present. The feed gas enters the pilot via tubing attached to the body. The gas then goes through a filter assembly to remove any particulates that could clog the integrated pilot plug assembly. If the supply pressure is below the setpoint, the pilot spring keeps the plug in the closed position. If supply pressure goes above the setpoint, the diaphragm assembly lifts to vent the loading pressure and opens the main seat. The regulator can be used as a part of separators, heater-treaters, and gas gathering systems.

Versatile Surface Analyzer Detects Transparent Materials
This surface roughness analyzer (SRA) precisely maps the topographic condition of a surface, which can provide insight into the wettability of the sample or its adhesion properties. The analyzer uses confocal microscopy to create a spatial representation of the surface. It stacks layers of 2D images, each one with a very small depth of focus, while lowering the optics in small increments to produce a height resolution representation down to 10 nm. The disk inside the analyzer has microlenses instead of holes (as in typical confocal microscopes) to increase the light yield and enable analysis of low-reflectivity or even transparent surfaces. The vertical transport of the measuring head uses an ultrasonic drive instead of a common piezoelectric drive for a greater height range. Lenses with magnifications from 2.5X to 100X can be exchanged quickly and easily to carry out a variety of tasks, from surface roughness analysis to imaging the exact shape of whole products. Because of its small size and light weight, the analyzer can be set up as a laboratory instrument or as a measuring head to be used for automatic processes in production lines, enabling real-time sample evaluations for quality control checks. The associated software can be linked to programs such as Matlab for integration into information systems.

Differential-Pressure Flowmeter Simplifies Process Construction Requirements
The Rosemount 9295 integrated differential-pressure flowmeter streamlines installation, operation, and maintenance. Its installation is simple and fast because all components arrive fully assembled and leak-checked, so field-welding, cutting, fabrication, and other initial tasks are not required. Although the flowmeter comes as a single assembly, it is designed to allow replacement of its individual components while in service to reduce downtime. It incorporates a conditioning orifice that eliminates the common requirements for straight runs upstream and downstream of a differential-pressure flowmeter. An all-welded design meets piping requirements for hydrocarbon applications and reduces potential leak points. Optional integrated resistance temperature detectors (RTDs) provide temperature readings to assist mass flowrate calculations. The isolation valves meet American Petroleum Institute (API) 602 requirements and are designed to operate through years of continuous service. The flowmeter uses the Rosemount 3051S differential-pressure transmitter to provide accurate readings and device diagnostic information via HART communication systems. The instrument is designed to withstand the challenging environments and piping requirements found in refineries, chemical processing, or other industrial settings.

Particle Separator Enables Continuous Operation
The gravitational classifier (GC) automatically separates soft, dry materials without the breakage, fragmentation, or fines generated by typical screens and rotary classifiers. This separator has no moving parts and prevents particle attrition by passing a current of air through a continuous stream of falling material, directing the particulates toward a series of vanes. Coarse particles (larger than 2 mm in diameter) drop into the discharge for collection while particles finer than the cutpoint (150 μm) exit the classifier via the airstream to a cyclone, baghouse dust collector, or cartridge filter. This pneumatic air classifier system separates dry particles without using any water and requires little power. Custom-designed and manufactured for each installation, the separator operates continuously in unattended setups with virtually no required maintenance. It efficiently separates salt, potash, limestone, fertilizer, manufactured sand, and other materials.
