a possible alternative or contact our Data Acquisition Engineering department.
You need to monitor the
temperature of a process across a
wide range and be immediately
notified any time, day or night,
if the temperature goes out of
specified limits. The OMA-VM520
will make a telephone call to up
to four phone numbers or pagers
to notify key personnel of a
temperature problem. Call
anytime and hear the temperature
of any sensor.
The OMA-VM520 is a full featured
temperature alarm system capable
of making alert telephone calls
when the temperature goes outside
of a user specified range.
The OMA-VM520 monitors up to
four (4) K-type thermocouple
temperature sensors, one (1) dry
contact alarm input, and power.
The OMA-VM520 has
programmable high and low
temperature limits and an alarm
time delay for each sensor. An
identification message can be
recorded for each sensor, indicating
where the sensor is located to allow
a quick response to a problem.
The OMA-VM520 has numerous
options that allow it to be configured
for any application.
The OMA-VM520 can monitor any
switch, relay, or dry contact with its
dedicated dry contact input. A time
delay can be programmed, enabling
a contact to be closed a maximum
amount of time before the buzzer is
activated and the OMA-VM520
begins its alarm procedures.
The OMA-VM520 will turn on the
alarm relay and buzzer and begin
making emergency notification calls
when the temperature of any sensor
is out of limits for greater than the
alarm time delay or if the dry contact
input is active.
The OMA-VM520 with Ethernet
Data Collection Package is also a
full featured temperature monitor
and temperature data logger that
can store temperature readings
on a computer.
Data Logging Capability
Do you need to keep temperature
records? Using the Ethernet Data
Collection Package with the
complimentary Data Capture
Program enables you to store your
temperature readings indefinitely on
your computer and analyze and
work with your data. The Ethernet
Data Collection Package version
(OMA-VM520-DCP) allows you to
collect data across your LAN and
store readings on PC. Also, alert
emails can be sent out to alert staff
to temperature issues. A built-in
web server allows you to use a
simple web browser to check
the temperature by entering the
IP address of the device into a
web browser.
