Shown is one of Dwyer’s ADPS differential pressure switches. Dwyer also introduced its new Series MS Magnesense® differential pressure transmitter and its new Series RH/RHL humidity/temperature transmitter. top chillers, and refrigerant recovery systems,” said the company. The product targets high volume applications requiring 2 percent “or better accuracy over the normal -40˚ to 85˚C operating temperature range.” The PT250 family of sealed industrial pressure transmitters is powered by a 9-32 vdc supply and provides a 4-20-mA output proportional to applied pressure. The compact units feature stainless steel housings and isolation diaphragms. Meanwhile, the MEMS-based P992/P993 low range differential pressure sensor family operates on a regulated 5-vdc power supply and is designed to provide amplified digital frequency output proportional to pressure. Omega Engineering (www. omega.com) touted several new transmitters. Its new iServer is “the simplest, easiest, fastest, most economical way” to connect almost any serial device (RS-232, 485 or 422) to an Ethernet network and the Internet without any special soft ware, it said. It also introduced the iDR series of signal conditioners and PID controllers. Meanwhile, its iFPX Internet Counter can count contacts from a button or switch, as well as count pulses from most any conventional transducer, such as a proximity sensor or quadrature encoder. The iFPX converts raw data to intelligent information. Its new Virtual Chart Recorder lets a person monitor and record the pressure and temperature of air (or inert gas) over an Ethernet network or Internet. The included transducer measures pressure from 0-200 psi and temperature from 32˚ to 158˚F. Onset Computer Corp. (www. onsetcomp.com) unveiled the ONLINE AT WWW.ACHRNEWS.COM ■ HOBO Remote Monitoring System, a state-of-the-art industrial-grade data logging system. The new system combines data logging hardware with built in GSM cellular communications and HOBOlink™, “a revolutionary new Web-based software platform,” it said. HOBOlink is designed to allow users access to current and historical data, set alarm notifications, and relay activations, and manage and control the system right from a desktop. Setra Systems (www.setra. com) showcased several new items, including its updated Micro-Cal Model 869 and Expert System, ultra-low pressure and documenting calibrator switches. The updated Model 869 calibrators’ additional features include a new Li-Ion battery pack, reduced weight (2 lbs lighter), a universal charging plug for different electrical outlets, and a new plug-in that allows charging while the lid is closed. The new Model 869 Expert System contains all of the new features of the new 869 and more. Next on the company’s “new” list are its CSS Series and CSC Series of current pressure switches. The CSS and CSC, which both utilize magnetic current sensing technology, are for HVACR, industrial, and lighting applications that use electric motors to drive fans, pumps, and blowers, and for sensing the status of heating coils and lighting. At the same time, its new Model SRH Humidity Series product line is designed to measure relative humidity in a room, duct or outside and is available in accuracies of ±2 percent, ±3 percent, and ±5 percent. The SRH Series features a replaceable sensor tip that “ensures an accurate, calibrated, and cost effective humid- ity control system,” stated the company. Also on the new forefront is its Model SRPM (Setra Room Pressure Monitor) Series, designed for pharmaceutical, hospital, semiconductor, clean rooms, research laboratories, and critical low differential pressure applications that require stringent pressure monitoring and alarming. The SRPM monitors the positive or negative pressure in protected environments and airborne infection isolation rooms per CDC guidelines. ■ eProduct #33 at achrnews.com 12/21/07 11:16:54 Ideal010708.indd 1 You can’t control Mother Nature but you can control your environment Keep your workspace clean, comfortable and productive • AIR CURTAINS • MAKE-UP AIR SYSTEMS Mars Air Systems featuring Dynaforce • ARES Mars Air Doors The only choice for an “Air of Quality”! 800-421-1266 Tel: (310) 532-1555 • www.marsair.com eProduct #43 at achrnews.com Product Literature Available Online February 18, 2008 25 http://www.idealtape.com http://www.idealtape.com http://WWW.ACHRNEWS.COM http://www.marsair.com http://www.marsair.com http://WWW.ACHRNEWS.COM http://WWW.ACHRNEWS.COM
