IPX II Series transmitter electronics will operate within specifications over the ambient temperature
range of 0°C to 80°C (32°F to 176°F). The location of the electronics housing should be in an area
where the ambient temperature is within this range.

Dynisco’s IPX II Series of Smart Pressure Transmitters provide a digitally enhanced 4-20 mA current
signal output that is transmitted to the control room via two wires. Proper electrical installation is
necessary to prevent errors due to electrical noise.

The power supply should provide 12-42 V dc. The load resistance is the sum of the resistance of the
signal leads and the load resistance of any indicator, controller, or other devices in the loop. Total

Failure to use the recommended mounting hole may result in erroneous pressure measurement,
difficult transmitter removal, premature sensor failure, process fluid leaks, and personnel hazard. In
applications involving high temperature operation and/or repeated thermal cycling a good, high quality
anti-seize compound should be applied to threaded surfaces.
