Compact gas handling

PARKER HANNIFIN CORP.. VERIFLO DIVISION. RICHMOND. CALIF. The VMB pressure regulator allows gas suppliers and panel builders to provide compact gas handling equipment, thereby minimizing the space required in clean room areas. It is a threadless-style, non-tied, double-diaphragm regulator for pressure control of high-purity gases. According to the manufacturer, the VMB is useful for valve manifold box or panel applications, to distribute highpurity gases to tools or locations in semiconductor fabrication facilities and high-technology manufacturing sites and laboratories. The VMB regulator has a compact footprint of just 1.25 sq. in. (31.75 mm). The pressure regulator also has a spherical poppet design that selfcenters for repeatable positive closure. Made from 316L stainless steel, with Hastelloy C-22 diaphragms and an Inconel poppet, the VMB is available with either tube stub or face seal connections.

Temperature datalogger

OMEGA ENGINEERING INC.. STAMFORD. CONN. The OM-CP-TEMPlOOOFP is a rugged, waterproof, portable, battery-powered, stand-alone high-temperature recorder. The compact device records up to 32,767 measurements at 0 -40° to 150°C (0 -40° to 302°F) temperature range. The data-logger is suitable for use in harsh environments. Its real-time clock ensures that all data is date and time stamped. One retrieves data by plugging the logger into the COM port of a computer. Software does the rest, converting the computer into a real-time strip chart recorder. Data can be printed in a graphical and tabular format or exported to a text or Microsoft Excel file. If the battery becomes discharged, the logger's non-volatile memory will retain the data until the battery is replaced. Price is $649.

Gas analyzers

MlDAC CORP.. COSTA MESA. CALIF. Titan-OL systems provide real-time, multicomponent extractive gas phase analysis for online and continuous multipoint analysis. These systems include a rugged industrial spectrometer system, gas cells, sample manifold, valve control electronics, and software. Hardware is enclosed in appropriately rated NEMA enclosures (up to and including Class 1, Div. 1) or in a standard industrial rack mount cabinet. Fiber optic distribution electronics provide a single hub for temperature, pressure, mass flow, external alarm, and optical switching signals, and can accommodate up to four 12-port manifolds for a total of 48 sample, purge, and calibration lines. Communication between the hub and control computer is over fast, stable fiber optic cable. Titan-OL systems take advantage of the company's new dual ADC architecture and advanced mirror drive control for increased sensitivity and very low detection levels for a variety of compounds.

Metal oxide sensors

SYNKERATECHNOLOGlES INC.. LONGMONT. COLO. The company has launched a new family of metal oxide sensors based on technology from specialist sensor materials developer Atmospheric Sensors LLC. This high-performance sensor for measuring NO^sub 2^ offers sensitivity over a range of concentrations of the gas in air combined with a high stability and low response to humidity. Other metal oxide sensors on the market today for NO^sub 2^ or NO^sub x^ measurement are usually restricted in the range of concentration where they are useful because of saturation effects, according to the manufacturer. The Synkera/ ASL product will tolerate a wide range of temperature, pressure, and humidity levels in addition to the usual rugged performance of a metal oxide sensor. The sensor also detects gas concentrations from O to more than 200 ppm. This sensor shows good selectivity and virtually no response to ammonia or carbon monoxide. Examples of market applications for the NO^sub 2^ sensor include measurement of exhaust levels in parking garages, and NO^sub 2^ measurement in certain automotive applications and combustion control applications.

Data acquisition

HElM DATA SYSTEMS INC., BELMAR. NJ. The GSR "DE" Series of data acquisition equipment has removable drives for high-security missions involving the acquisition of sensitive data. Suitable for ground-based telemetry, satellite downlink, and test cell recording, the GSR "DE " Series features all-digital recording, high data integrity, flexible signal interfacing, and removable media. This economical, rack-mounting, 256 Mbit/s digital recorder can simultaneously acquire multiple streams of data from analog, digital, communications, video, and avionics bus sources. Once the data is acquired, it is recorded to storage media for later retrieval and analysis. Data retrieval may be by real-time construction of original signal sources or by direct high-speed transfer of digital data to the user's computing platform over bus and network interfaces.
