Additional Features
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.

In the data specs, is "TD" referring to "Total Differential"?
TD means Turn Down, it is the ratio of the full-scale output over the current scaled output.
Turndown = nominal range of the device/set span of the device

wich cable shoud I use for computer connection? is it this one "Twist Lock Connectors for Pressure Transducers and Load Cells''
Bramay, no cable we have will help you connect to a computer. You will need a data acquisition system. Please email us at das@dwyeromega.com for help selecting a DAS device.

Of the ports that are marked (H) and (L), which of the two is the (IN) port and which one is the (OUT) port.?
This is not a flow through sensor. The pressure applied to each port react on a internal diaphragm. The unit internally calculates the differential between the two applied pressures and output a signal represents this differential.
Date published: 2022-10-13
Just to confirm. The "WET/WET" means it is measuring pressure differential in fluid not in gasses. Correct?
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 "H2O DP Transmitter to 0-278 "H2O. correct?
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" wc.

What is the size of mounting screws (female threads)? Is it metric or imperial?
It would imperial. The pressure port is ¼-18 NPT.
Date published: 2023-12-18
For tank level measurements with high solids content fluids do you recommend an additional isolation diagram to be installed or is this unnecessary?
We recommend using an isolation diaphragm in this type of application. A high content of solids can easily clog the input port connections on this sensor.
Date published: 2022-01-11
Being outside the measurement range, can I have one side at 1 bar and the other at 100 bar? Or do I break the membrane ? (e.g. PX3005-150dwi sensors)
Hello, we do not recommend using this device outside the calibrated range. The diaphragm could see plastic deformation that could affect your zero and span balance. It would be best to go with a higher range.
