Product Specs

The Omega differential PX3005-DIFF is a compact, rangeable, pressure transmitter ideal for monitoring pressures in process automation, hydraulic systems, compressors, pumps, and in tank level applications where consistent, reliable pressure measurement is essential. The PX3005-DIFF utilizes a unique encapsulation construction of a MEMs piezoresistive pressure sensor coupled to an advanced microprocessing to provide superior accuracy and performance.

The unique construction enables high line pressure operations and superior protection from pressure overloads. The rugged 316 stainless-steel enclosure is IP67 rated making it suitable for wash down environments. A 5-digit backlit LCD allows for a full precision representation of process variable. Available in ranges from 1 to 1,500 psi, the intelligent transmitter module allows for configuration of the 4 to 20 mA signal, display of input or output, and choice of 19 measurement units. The output signal can be adjusted to re-arrange the transmitter or “tare” unwanted fluid head preloads. Rangeability is capable of adjusting zero and span are from -100 to 100% FS URL (Upper Range Limit) with a minimum span of 30% URL. This means a 15 psi transducer can have the zero set between -15 to FS 15 psi. For example, zero could be set for -15 psi and maximum 15 psi so the output would be 4 mA at -15 psi, midpoint 12 mA would be 0 psi and 20 mA would be 15 psi.

Dimensions: mm (inches)

Turndown = nominal range of the device / set span of device
EXAMPLE: a PX3005-1KWDWBI with set span of 500"H2O TD = 1000"H2O/500"H2O = 2

How rangeable are these transmitters? Can I do a -50 to +50 inH2O with the transmitter that does -160 to 160 inH2O (model PX3005-160WDWBI) Thanks much for any responce.

Asked by: Aquamann
The PX3005 series has a very large turndown capability and can easily be set for a -50 to +50 inch of water range. In fact, the minimum span can be set as low as 1.6 inches of water. Thank you for contacting Omega and please feel free to contact us again if you have any additional questions.

Just to confirm. The &quot;WET/WET&quot; means it is measuring pressure differential in fluid not in gasses. Correct?

Asked by: MarkM
Thank you for your inquire The units that state wet wet can be used in liquid or gas.

I can range the -1000 to 1000 &quot;H2O DP Transmitter to 0-278 &quot;H2O. correct?

Asked by: belzebub
Yes they can. These unit are actually scalable so you can turn down the range of the unit do give you the full 4 to 20mA output signal over 0 to 278&quot; wc.

What is the size of mounting screws (female threads)? Is it metric or imperial?

Asked by: Marcin
It would imperial. The pressure port is &frac14;-18 NPT.
