- User-configurable display of dewpoint in °C or °F dewpoint, ppm(V), ppb(V), ppm(W), g/m³ or lb/MMSCF, factory pre-configured to customer order
- Linear 0-20/4-20 mA isolated retransmission signal
- User input of pressure for pressure dewpoint conversion
- Natural Gas data built-in
- Programmed with mol weight of common gases for ppm(w) measurement, user programmable for other gases
- 5 digit primary display plus secondary display of selected unit
- 2 programmable alarm relays
- Front panel protection to IP55 / NEMA 12
- Exd option for installation in Ex Hazardous areas. Flameproof to ATEX and IECEx Certification for use in potentially explosive atmospheres
The DS4000 Dewpoint Hygrometer is a panel mounted single-channel Indicator specifically designed to work with an Alpha Moisture Systems online Transmitter for continuous trace moisture measurement in gases and dry compressed air and dry rooms/chambers.
The user can configure the DS4000 system to read in °C dewpoint, °F dewpoint, ppm(V), ppb(V), g/m³ or lbs/MMSCF. The measured value is displayed on a large five-digit LED display.
The Indicator offers a selectable 0-20 mA or 4-20 mA isolated retransmission signal and two programmable alarm relays, which can be independently set across the operating range of the Transmitter.
When combined with the specified Signal Isolator inside the optional Exd enclosure, the DS4000 can take readings from the intrinsically safe AMT-Ex Transmitter in hazardous areas with potentially explosive atmospheres.
The DS4000 Dewpoint Hygrometer is our flagship Indicator, fully-featured with the ultimate versatility of a user-configurable display.
