FOR IMMEDIATE RELEASE

Multiple temperature monitoring system

Omniflex has OmniWatch - a temperature monitoring system with a difference: sixteen temperatures can be monitored at once, from any 3 wire RTDs or thermocouples

 

No multiplexing and no rotary switches.The temperatures may be from any 3 wire RTDs or thermocouples.
Cold junction compensation and linearisation are standard features.
Alarms and alarm annunciation.
Each temperature input has an alarm and trip setpoint allocated to it the setpoints are configurable via the front panel keypad.
Each setpoint is represented by an LED indicator which can be configured with an optional annunciator sequence forcing an operator to silence the audible, and acknowledge the alarm.
An auto reset or manual reset option can be chosen.
Temperature channel display.
Each temperature channel may be viewed in turn on the front panel LCD display with its setpoints by using a scroll button.
Omniwatch has an option to automate the display so that the display automatically scrolls through the channels at a specified time interval.
Alarm and trip outputs.
Each setpoint can have a relay or open collector output for the alarm status, these can be used to drive external devices when the setpoints are reached.
Group alarm function.
To save on relay outputs group alarm functions are used to bring up alarm for the attention of operators.
There are 4 group alarms.
One each for setpoint 1 and setpoint 2.
And one each to function as a high high or low low group alarm.
Every input is mapped to the group alarm.
Optional re-transmit.
The temperature inputs can be re-transmitted to another device as 4-20mA outputs by simply fitting an analogue output module to the OmniWatch.
Every alarm or trip is date and time stamped as it occurs.
This is useful for stringent quality control systems where recording of alarm and trips are required.
These events are available to the conet local area network which can the route them to a SCADA database system.
Omniwatch has a history log which captures the last 64 trips and alarms with it's date and time stamp and this can be viewed via the front panel of the OmniWatch.
Operators thus have access to the latest information.
Local area network connections and SCADA.
Up to 127 Omniwatch devices may be connected to a single twisted pair cable running the Omniflex local area network - CONET.
Conet is supported by most SCADA packages and can thus acquire the information from Omniwatch devices including all date and time stamped information.
