NC-1732

Optimum combustion reduces your fuel bill and helps the whole world and future generations by reducing harmful greenhouse gas emissions.
The current high cost of fuel has helped to reduce the payback period for the cost of installing oxygen monitoring and air / fuel ratio control.
It makes sense to consider the benefits of installing an oxygen system on your combustion process.
The NC-1732 oxygen transmitter is suitable for gaseous oxygen measurements in a variety of processes. These are some of those processes that the NC-1732 is designed for:

Alarms

Common alarm relay with 20 user selectable instrument alarm functions. Three programmable process alarm relays for very low oxygen, low oxygen, high oxygen, oxygen deviation, probe temperature low, cal check in progress, purge in progress, plus any alarms that were not selected for the common alarm. Multiple selections can be made for all relays.

Alarm Contacts

  • 2A / 240VAC, 2A / 30VDC

Range of Logical Indication

  • 1.0 x 10-30% to 100% O2
  • 0.01ppm to 10,000ppm – automatically defaults to exponential format below 0.01ppm and percent format above 10,000ppm (1%)

Serial / Network Interface

RS232, RS485 MODBUS™
