New Easidew 2-Wire Dewpoint Transmitter

Description

Kahn Instruments, a leading manufacturer of advanced moisture-measurement instrumentation, is proud to announce that we have upgraded our Easidew Dewpoint Transmitter. The new and improved Easidew 2-Wire Transmitter is a low cost, rugged dewpoint transmitter for continuous measurement in compressed air or process gas.

New and improved features include:
  • The ability to be connected in a 2-wire, loop powered configuration, while maintaining complete backward compatibility with all existing 3-wire installations
  • An output that is configurable in PPMv moisture content (0-100, 0-1000 and 0-3000 PPMv ranges)
  • A new 10 micron HDPE sensor guard designed to show contamination for service ease
  • Improved software and firmware to protect calibration from the most severe levels of EMI
The Easidew Transmitter has a dewpoint measurement range of -148°F to +68°F and an accuracy of ±3.6°F. The instrument also features a field adjustable 4-20 mA linear analog output, resettable failure modes for Over Range, Under Range and Sensor Fault conditions, and temperature compensation.

The Easidew Transmitter is economical to purchase, install and maintain. Volume manufacturing allows Kahn to keep the price low. Installation costs are minimal, because of the transmitter’s ruggedness and simplicity. And ongoing operating costs are low, because the Easidew Transmitter is reliable and durable. Only periodic re-certification is required to maintain calibration accuracy. Kahn even offers an exchange program so a customer’s process is never out of operation.
