MicroMet Integrated Data Acquisition Units
Models 455B, 456B
The central “brain” of the modern
weather station is the data acquisition unit, or DAU. It is here that the
data collected by the sensors are recorded, manipulated, and stored for
future use and analysis. The DAUs offer the highest degree of integration
and ease of use available today.
| THEY ARE DESIGNED TO PROVIDE THE ENVIRONMENTAL ENGINEER WITH |
|
A built-in datalogger, scaled directly to the recorded measurements, provides an easy to read, permanent record of the measured meteorological variables. The system includes the datalogger, the interface board, and panel-mounted Smart Keyboard/ Display. Provision is made for the addition of an optional Storage Module for extended memory capability.
An RS-232 dataport is available for direct
communications with a computer or terminal. Amodem may be added to facilitate
remote access of the datalogger for programming or data retrieval. Password
protection and automatic shutoff of the display provide additional data
security. Standard unit provides 12 analog and 2 pulsed signals, expandable
with additional analog or digital inputs or outputs. The motherboard includes
lightning protection diodes, and provides a charging function for a backup
battery (optional with the Model 457).
| Display |
| Power turns on the keyboard display and prepares the unit for further operator interaction. |
| Time/Date |
| Time/Date will return the datalogger time. Press again to display datalogger date. |
| Scan Inputs |
| Scan Inputs key will display the data going into the system in channel #1. By using the Arrow keys, other data channels can be viewed. |
| Scan AVGS |
| Scan AVGS key will return the data most recently written to datalogger memory. The Arrow keys allow viewing all the elements of the array. |
| Verify Program |
| Verify Program key will display the program signature, a number unique to the specific program. This feature alerts the operator if a change has been made to the datalogger program. |
| Program key |
| Program key, which is password protected, allows access to the datalogger’s native programming functions and/or the SKB functions. |
Standard equipment includes datalogger, computer
interface, lightning protection and memory backup battery (optional with
the Model 457), direct sensor hookup, graphic user interface, and enclosure.
Differences between model numbers relate to features and packaging. They
are functionally equivalent.
| MODEL 455B | |
| This full-featured device provides virtually everything needed for a complete and total weather data system. All hardware is mounted within a high quality compression molded fiberglass enclosure. The enclosure is designed specifically for harsh manufacturing conditions and hostile environments, and will outlast steel or stainless steel in a corrosive or marine environment. The enclosure meets and exceeds most NEMA grade specifications. Door hinges are molded, with stainless steel hinge pins. Cable entry is through a port in the enclosure bottom, fitted with a sealing clamp. The enclosure contains a latch with integral tumbler lock for security. |
|
| MODEL 456B | |
 |
This unit offers all the features of the Model 455, but is designed for mounting in a standard 19” equipment rack. The panel height is 7,” and the minimum depth required is 15.” Terminal blocks are provided for direct sensor cable connections. A metal chassis cover or benchtop enclosure is available to allow this model to function as a benchtop unit. |
| OPTIONS |
|
To optimize the unit to your specific application and requirements, a broad range of optional configurations and accessory components are available. A complete range of meteorological sensors may be added to the system, including, but not limited to, wind speed and direction, temperature, relative humidity, solar radiation, and precipitation. Instrument carrying cases are available for all sensors. Expanded memory storage modules are available for
applications requiring longterm unattended operation. (The standard
internal memory will allow recording hourly averages of 15 inputs
for 130 days.) Communication options include conventional or shorthaul
modem, interfacing cables, and data manipulation software. A backlit
display will allow easy viewing in poorly lighted environments. Due
to the power required, this option is only available on AC powered
systems. A multi-channel graphic recorder may be interfaced to the
DAU, allowing for hard-copy backup of important data. Please consult
your Met One Instruments sales specialist for additional information
on these options and accessories. These units are designed for easy
installation and maintenance by non-technical personnel. As with all
equipment, technicians and engineers |
