Clark Solutions' Differential Pressure Indicator & Transmitter Ideal For HVAC Applications

Online, May 4, 2010 (Newswire.com) - Hudson, MA-Clark Solutions announces the availability of the company's 699 Series Differential Pressure Indicators and Transmitters featuring proven ceramic sensor technology. 699 Series Indicators and Transmitters are designed for use with air and non-corrosive gases. 699 Series deliver adjusted temperature-compensated sensor signals (available as standard voltage or current outputs). They are ideal for monitoring low air velocities in air conditioning systems, the measurement of low differential room pressures in laboratory and process clean room applications, and other low pressure monitoring applications such as hospital infectious disease rooms and inflated building pressures.

699 Series Indicators and Transmitters are available in three configurations, offering different levels of function and cost. Configuration 1 is a transmitter with field selectable ranges, factory preset output signal, and zero offset configurations. Configuration 2 incorporates a 10-position DIP switch, allowing field selection of range, output signal, and response time. A potentiometer allows further adjustment of span within the selected range. Configuration 3 incorporates an LED display and full field function programming via a programming button, including setting of range and fine-tuning of span, output signal, zero offset, units of measurement, response time, square root extraction and display light settings.
