View Barometric Pressure, Temperature, and Humidity with a Web Browser
The OMEGA® iBTHX transmitter lets you monitor and
record barometric pressure, temperature, relative
humidity, and dew point over an Ethernet network or
the Internet with no special software except a Web
The iBTHX serves active Web pages to display real
time readings; display charts of barometric pressure,
temperature, and humidity; or log data in standard
data formats for use in a spreadsheet or data
acquisition program such as Excel or Visual Basic.
The virtual chart viewed on the Web page is a JAVA™
Applet that records a chart over the LAN or Internet in
real time. With the iBTHX, there is no need to invest
time and money learning a proprietary software
program to log or chart the data.
Chart scales are fully adjustable on the fly. For
example, the chart can display one minute, one hour,
one day, one week, one month, or one year.
Temperature and humidity can be charted across the
full span (-40 to 85°C and 0 to 100% RH) or within any
narrow range (such as 20 to 30°C). Barometric
pressure can be displayed in hectopascals (hPa),
millimeters of mercury (mmHg), or inches of mercury (inHg).
Display and Chart Measurements
The iBTHX transmitter comes complete with a
barometric pressure, temperature, and humidity probe
for measurement of a single location.
OMEGA® offers a choice of industrial probes in 5"
lengths, and a wand style for ambient indoor
The OMEGA® iBTHX is simple to install and use, and
features OMEGA’s award-winning iServer technology
that requires no special software except a Web
The iBTHX connects to an Ethernet network with a
standard RJ45 connector and sends data in standard
TCP/IP packets. It is easily configured with a simple
menu using a Web browser, and it can be password
From within an Ethernet LAN or over the Internet, the
user simply types an IP address or an easy-toremember
name such as “Cleanroom 5” or “Midwest
Server Room” in any Web browser, and the iBTHX
serves a Web page with the current readings.
All OMEGA iBT(H)X models that are on a LAN connected to the Internet
can trigger an alarm that can be sent by email to a
user or a distribution list anywhere in the world,
including text messages to cell phones and PDA's.
The OMEGA iBTHX is excellent for monitoring
temperature and humidity in applications such as:
clean rooms, computer rooms, HVAC systems,
pharmaceutical/food processing and storage,
hospitals, laboratories, semiconductor labs, electronic
assembly, warehousing, museums, manufacturing,
greenhouses, and farm animal shelters.
NEW iBTX-SD with SD Flash Memory and LCD Display
The OMEGA iBTX-SD with LCD display adds several
valuable features to the backlit local display of
temperature and barometric pressure.
SD Flash Memory Card
The iBTX-SD comes complete with a removable 2 GB SD Flash
Memory card that can store up to seven years of readings
taken at ten second intervals
Records on SD Flash Cards
The data is recorded on widely available SD (Secure Digital)
flash cards. The format is a simple “.txt” text file that is
easily imported to spread sheets and other programs.
It can be read on a PC or MAC with a USB card reader.
You can also download the data remotely over an
Ethernet network or the Internet.
The iBTX-SD features two 1.5 Amp relays.
With the easy Web-based setup page, the two relays can
be programmed for any combination of temperature or
pressure, and high or low set points. The relays can also
be programmed to remain latched and require a manual
reset if a limit is exceeded.
The iBTX-SD comes with a universal 100 to 240 Vac power
adapter. A standard 9 Volt Alkaline battery (also included)
allows the device to log data for up to 2 days without external
ac power. A failure on the Ethernet network will not interrupt
Link to Web CAM or IP Camera
If you get a message about an alarm condition, you can quickly click on the link to view the actual scene over the Internet.
