Infrared gas monitor suited for petrochem operations
The Chemgard infrared gas monitor is a complete, flexible platform suited for gas monitoring in petrochemical operations. With monitoring ranges from 0-10 ppm to as much as 100% by volume for select gases, including LEL monitoring, a durable NEMA 4 enclosure, and advanced photoacoustic infrared sensing technology, the unit promises accurate, reliable low-level leak detection and process monitoring.
General hydrocarbons including methane, pentane, propane, and hexane; aromatic hydrocarbons such as benzene, toluene, and xylene; and a variety of fuels-gasoline, diesel, and jet fuels-can be detected with the monitor. Uses include tank farm, pipeline, and hydrocarbon bed breakthrough monitoring.
Its photoacoustic infrared sensing, a high-performance, low-cost gas detection method, is the technology of choice for low ppm or ppb monitoring. It is stable, with virtually no zero drift, and it helps reduce interference effects from background gases and humidity.
Featuring an electrochemical or catalytic bead auxiliary sensor option, the monitor can simultaneously detect either oxygen, carbon monoxide, or combustible gas, along with one of more than 100 infrared-active compounds. The auxiliary sensor gas concentration can be monitored through the unit display or a 4-20 ma analog output, and the sensor fits conveniently inside the standard Chemgard monitor enclosure.
The monitor is available in a NEMA 4 wall mount, a 19 in. rack mount, or an explosionproof enclosure, all with four, front-panel button controls. Each version can monitor one to eight sample point locations and provides three levels of alarm control.

New suite of drilling services
The new FullDrift drilling suite includes the SlickBore matched drilling system, the Geo-Pilot rotary steerable system, and the new SlickBore Plus drilling and reaming system. The new suite of tools can help deliver a quality hole, free from spiraling and tortuosity, the company says.
The suite can provide benefits of a quality hole in sliding and rotary drilling, the firm points out. It also promises solutions for difficult drilling problems, such as subsalt plays.

Transducer adds temperature output option
A temperature output option has been added to a line of KPSI level transducers. The new option enables the transducers to monitor the temperature of the measured process in addition to measuring level and pressure. The temperature output option is designed for a range of tank and well level control and monitoring applications.
Available on transducers with two wire, 4-20 ma output, and supply voltage ranges of 9-30 v dc, the new feature can be selected for the following submersible and aboveground KPSI level transducers: Series 700, 710, 720, 730, 735, 27, 28, 30, and 35.
Operating ranges of applicable transducers are 0° C. through 50° C. (32° F. through 122° F.) and -20° C. through +60° C. (-4° F. through +140° F.). Transducers with the temperature output option also carry UL, FM, and CSA approvals as standard.
