Products making their way into the process control industries marketplace this month include a flue gas oxygen analyzer from Emerson Process Management , an integrated safety system from Yokogawa Electric Corp. , and a programmable current/voltage and RTD/thermocouple limit alarm trip from Moore Industries-International Inc . Details about each are provided here, along with links to additional information.

Rosemount Analytical SBX 1000 is the latest addition to the Emerson Process Management family of flue gas oxygen analyzers. Device integrates an oxygen probe and field electronics in one package to provide a way to optimize fuel-to-air ratio for processes up to 1,300 °F (700 °C). It inserts into the flue gas duct for fast, accurate, and reliable measurements, without sampling, the company says. Electronics housing and probe is an integral unit to eliminate the need to mount separate electronics or run cable between the probe and electronics. No calibration is required at set up. Outside part of the analyzer operates in temperatures to 185 °F (85 °C).


SPA2 programmable current/voltage and RTD/thermocouple limit alarm trip from Moore Industries-International Inc. provides on/off control, warns of trouble, and can perform an emergency shutdown.

ProSafe-RS safety system from Yokogawa Electric Corp . is intended for integrated use with process automation applications. Used to constantly monitor the status of oil, natural gas, petrochemical, and other process applications, the system is designed to ensure safety by shutting down a plant whenever an unexpected condition is detected. System can be integrated with Yokogawa’s Centum series of process control systems, eliminating the need to build process control and safety systems separately and allowing plant information to be managed centrally.

SPA2 programmable current/voltage and RTD/thermocouple limit alarm trips from Moore Industries-International Inc . provide on/off control, warn of trouble, and can perform an emergency shutdown by sending up to four relay outputs when a monitored process signal falls outside a user-selectable high or low limit. They accept input signals from transmitters, temperature sensors, resistance and potentiometer devices, and direct millivolt sources. In addition, they provide two or four independent and individually configurable alarm relay outputs. On-board controls or the company’s free PC configuration software may be used to program each individual alarm trip relay as a high- or low-limit process alarm, rate-of-change alarm, input fault alarm, or self-diagnostic alarm. Other features include 20-bit input resolution; a metal, RFI resistant DIN-mount housing; and a large, 5-digit process and status readout.
