DPT-2011 DEW POINT TRANSMITTER

The DPT-2011 Single Stage Dew Point Transmitter uses the chilled mirror principle to determine the absolute humidity of any gas in terms of its dew- or frost-point temperature. It was specifically designed for laboratory, field and industrial process applications. The control electronics maintain the sensor mirror to the equilibrium point where a dew or frost layer is established on the mirror surface. A platinum resistance thermometer directly monitors the mirror temperature. Depending on the actual dew point, settling time from ambient may take a few seconds to one minute. A local digital display and analog and digital interfaces are provided.

Chilled mirror dew point hygrometers are used in industrial process-control and laboratory applications to ensure product quality, including:

Real time production process control of pharmaceutical, plate glass, paper, plastics

Production monitoring for dried foods and dry snack processing

Monitoring of storage environments and special purpose rooms such as museums, warehouses, computer and clean rooms

Manufacturing quality control for fabrication of sensitive electronic components such as semiconductors

Building HVAC or air quality monitoring

A front-mounted threaded hole plug supports access to the chilled mirror for periodic cleaning. Sample gas typically passes through the system via a flow gauge and filter tubing connections. Flow rates from 0.5 to 1.0 standard cubic feet per hour (SCFH).

DPT-2011 Single Stage Dew Point Transmitter

A front panel digital panel meter indicates the current dew point temperature. A pushbutton lets you rapidly check that the mirror is clean without having to open the sensing chamber for inspection. An LED indicates when cleaning is required. Both RS-232 serial and 4-20mA analog outputs are provided. The serial interface supports a graphical LabViewÔ application for MS-Windows9x/NT that permits you to view real time sensor data on a PC or Mac.
