Moisture Analyser - ODP 5000

Moisture Analyser | Dewpoint Transmitter | Continuous control of moisture -100°C to +20°C DEWPOINT

General

Orthodyne Moisture Analyser & Dewpoint Transmitter

The Orthodyne digital Moisture Analyser are designed as compact, simple and reliable instruments, which will continuously monitor air dryer performance, compressed air quality and dry gas moisture, from ambient dewpoint levels to as low as -100°C.

Principle

ELECTRONICS

The transmitter electronics take full advantage of state of the art microprocessor technology and offer many advanced intelligent features. With optional dual alarms, analog and digital outputs, the Orthodyne Dewpoint transmitters can be used as indicators, alarm units or controllers.

PROGRAMMABLE ALARM RELAYS OPTION

The two optional alarm relays can be independently programmed to switch at any dewpoint with variable hysteresis, which makes the transmitter ideally suited as an energy saving controller for desiccant dryers in “dewpoint demand” mode or safety cut off in process control, high power laser, etc. The status of the relays is shown on the display with flashing HI or LO indicators while displaying the dewpoint.

ANALOG AND DIGITAL OUTPUTS (OPTIONS)

Analog and digital outputs are isolated from the sensor. The analog current or voltage output can be programmed to span the full or a portion of the range and is linear to the selected engineering units. The RS-232 interfaces into the serial port of any PC or Mac, for a simple operation with any standard communications program.

USER FRIENDLY INTERFACE

The instrument is operated through a menu driven user interface consisting of a custom LCD display with optional backlight, and four push buttons.

ENGINEERING UNITS

The user can select from the following engineering units. Dewpoint in °C or °F, ppmv, g H2O/m3, lbs H2O/ million scf.

PRESSURE CORRECT FUNCTION

Results are displayed at sensor pressure or by pushing the Pressure Correct key at a user selectable alternate pressure, such as the line pressure.

SPAN CHECK IN THE FIELD

This field calibration procedure is fully automated and the user is prompted through a simple one minute procedure, which requires no additional equipment.

ERROR INDICATION

The instrument has indication for sensor open, short or electronic system failure, which can activate any of the alarm relays.

NIST / NPL TRACEABILITY OPTION

Certificates for NIST and NPL traceability are available upon request. Instruments can be recertified periodically at our laboratories
