OMEGA’s PX51 Series consists of high-accuracy, low-cost pressure transmitters. Their sealed, all stainless steel construction makes them suitable for the harshest environments. They are available in gage, absolute, or sealed gage models. Ten feet of PVC insulated shielded cable is standard, or a twist-lock style connector is also available. This latest addition of the FM Approved Intrinsically Safe version for Hazardous Locations (available with 4-20 mA output) only further expands the range of applications of this versatile product family.

FM ApprovalsRecognized and respected across the globe, FM Approvals certification assures customers a product or service that has been objectively tested and conforms to the highest national and international standards. Please refer to FM Approvals for downloadable copies of FM Approvals Certificate of Compliance and Installation Control Drawings.

The PX51-IS is also available in metric configurations, with ranges from 0-0.7 bar to 0-400 bar ranges and metric threads. Please see PXM51-IS for complete details, or contact our Pressure department for more information.

Do the nameplates on these units include the words "single seal" or "dual seal"? If not, then we'd need to utilize a separate secondary process seal for compliance with NEC 501.17. Thanks.

Asked by: Nemisis
Our device does not rely on a seal, they are fully welded, there is no path that relies on a seal to prevent the process fluid from reaching the electronics of the device, so no additional sealing is required. In addition, The construction has many fails safes in addition to being separated by welded material. In the event of the MEMS device failing, an overload surface restrains the stainless still diaphragm from rupturing.

Do you have a barrier that is known to work or has been tested with the Intrinsically Safe version?

Asked by: datasheets
Thank you for your inquiry. We do not offer any intrinsically safe barriers for a 4 to 20mA output device. You will have to source a barrier from a supplier of this type of product.

Does this device have any sort of overpressure rating? Thanks.

Asked by: JCPr
Thank you for your inquiry. Safe overpressure rating is 150% of the rated pressure range. Burst pressure rating is 300% of the rated range
