Any Refrigerant. Any Place. Any Time.® FOCUS AHR EXPO POST-SHOW ISSUE Transmitters, Sensors Upgraded and Improved By Mark Skaer Of The NEWS Staff EW YORK — Sensors and transmitters continue to be upgraded and improved upon. In alphabetical order, here are what manufacturers introduced as new at the 2008 Air-Conditioning, Heating, Refrigerating Exposition (AHR Expo). ACR Systems (www.acrsystems. com) released its low-pressure differential data logging kit. It features the SmartReader Plus 4 LPD data logger “with extra-fine pressure resolution” designed for commissioning, testing, and balancing HVAC systems. Also included is TrendReader 2 data logger soft ware and a USB communication cable. The company said installing a pressure differential data logger “across the fi lter banks will prevent personnel from having to guess whether the fi lter is ready for replacement.” Ashcroft (www.ashcroft.com) said its CXL low-pressure transducer, thanks to its small housing and multiple mounting options, can be mounted on a DIN rail, conduit, or wall. With a convenient detachable terminal block N electrical connector, the CXLdp can be installed into a panel without power interruption. Meanwhile, its new G2 pressure transducer has an accuracy rating at 1 percent total error band. It is available in pressure ranges from 0/30 to 0/20,000 psi and offering broad choices of outputs, electrical terminations, and process connections. Also, its DXLdp low differential pressure transmitter is “a favorite for critical airflow, room pressure and air-handler management applications,” said the manufacturer. Equipped with the exclusive Ashcroft® SpoolCal option, this transmitter can be validated, zeroed, and calibrated while online, “without ever having to disconnect the pressure tubing,” it stated. Diagnostic indicator lights and easily accessible test jacks enhance the ease of testing while DIN rail mounting makes installation a “snap,” it said. Dwyer (www.dwyer-inst.com) introduced two transmitters. Its new Series MS Magnesense® differential pressure transmitter is “an extremely versatile transmitter for monitoring pressure and air velocity.” Features include field selectable English or metric ranges, field upgradeable LCD display, adjustable dampering of output signal, and has the ability to select a square root output for use with pitot tubes and other similar flow sensors. Its new Series RH/RHL humidity/temperature transmitter is designed to monitor humidity or both humidity and temperature in a single device. It has a 2 percent to 3 percent accuracy, dual 4 to 20 mA or 0 to 10 VDC outputs in humidity/temperature models, and field selectable temperature units. Honeywell Analytics (www. honeywellanalytics.com) introduced 301W, its first wireless gas detector designed for parking structures, and IAQPoint, which the company terms “a low-cost,” indoor air quality monitor designed to measure carbon dioxide, temperature, and humidity levels for demandcontrolled ventilation (DCV) in office towers, schools, and other commercial buildings. The 301W detector is designed to monitor carbon monoxide and nitrogen dioxide in parking structures. NEW PRODUCTS Kanomax (www.kanomaxusa.com) introduced its airflow transducer, Model 6332; facility monitoring laser particle sensor, Model 3714/3715; and its aerosol particle mass analyzer, Model APM-10. The airflow transducer features 10 interchangeable probe options, and selectable output or current. It is designed to prevent exposure of hazardous materials to workers and prevent leakage by thorough monitoring and control of chamber airflow. The Model 3714/3715 features built-in sonic nozzle for accuracy and consistent flow, plus has built-in LEDs for sensor status at a glance. The aerosol particle mass analyzer is designed to classify the mass of a single aerosol based on the balance between the centrifugal power and electrostatic power. Kavlico Corp. (www.kavlico. com) pointed out its high volume refrigeration pressure sensors, low-range differential pressure frequency output sensors, and industrial transmitter family. The P528 family of ceramic capacitive refrigeration pressure sensors “are perfectly suited for high volume applications in refrigeration compressors, roof■ eProduct #66 at achrnews.com efron012808.indd 1 1/3/08 9:11:13 AM “ Purchasing the Rotobrush has been great for our company. Because we have Rotobrush and provide air duct cleaning as an additional service, we are getting in the door of our competitions’ customers and making them our HVAC customers.” - Pam Myers, HVAC Contractor HVAC professionals are talking about Rotobrush. Fact is, if your customer goes to a competitor for air duct cleaning, they’re likely to start using them for equipment replacement and servicing. Rotobrush can help you add air duct cleaning to your residential or commercial business — quickly and easily. • • • • • No franchise fees One person-operated, portable system Hands-on and classroom training 24/7 tech support One job per month could pay for the package “ I saw my competitors were proposing duct cleaning on every bid. So we bought a Rotobrush and include duct cleaning as added value any time we sell a high efficiency system. As a result, my closure rate increased from around 40% to 86%.” - Rick Nees, HVAC Contractor As the market leader in air duct cleaning, we’re helping HVAC professionals stay competitive and hold on to their customers — and that has everyone talking.
