NOxGuard / NOxTempGuard
NOx Analysis and Display Unit
Item no.: 2050003
The NOx evaluation and display unit, which includes temperature sensing and an archiving function, is designed for installation in a control cabinet. It can simultaneously monitor two NOx measurement points. These can be located either on two separately operating gas engines or on both cylinder banks of a V-engine.The sensors are connected directly to the unit using ENSERV system cables. No additional wiring is required to ensure the monitoring function; however, the engine control system must also send a signal to the NOx monitoring system indicating the engine start in order to initiate measurement data acquisition.The NOxTempGuard is powered by 24V.Upon request, your logo can be programmed to appear on the screen.

Description
In NOxTempGuard, two different operating hour limits can be set for each sensor:Warning threshold (after 12,000 h): If 12,000 operating hours are exceeded, the operator is notified that the sensor must be replaced within the next 1,200 hours.
End-of-Life Threshold (at 13,200 h): Once 13,200 operating hours (1.5 years) have been exceeded, the sensor—according to general consensus—has worn out to the point where it no longer provides reliable readings and must be replaced. A message appears, and from that point on, all measured values are highlighted in red. These values can be changed in the setup menu (password-protected) if new findings emerge or if the legislature itself prescribes specific values. However, the following always applies: “The end-of-life hour count is greater than the hourly warning threshold.”A web server is integrated into the NOxGuard/NOxTempGuard. To administer the controllers remotely, you need either remote access via VPN directly to the device or via TeamViewer to a PC on the same network. This allows the NOxGuard/NOxTempGuard controllers to be conveniently accessed via a web browser.NOx evaluation and display unit with archiving function in accordance with 44. BImSchV
