Metric, High Accuracy, Intrinsically Safe Pressure Transmitters

The PXM509 intrinsically safe transducers are rugged all stainless steel transducers specifically designed to meet the requirements for use in hazardous locations for all classes and zones.
Features include welded stainless steel construction, user accessible potentiometers, and a demountable electrical termination end. They are designed for rugged industrial applications, and have high shock and vibration ratings and excellent long term stability.
A precision micromachined silicon sensor is at the core, and provides a very stable reading with exceptional high accuracy of 0.08% and a broad compensated range of -29 to 75°C (-20 to 167°F) on most ranges.
Modular construction allows for fast delivery of most configurations and fittings including agency approved models, plus, customized models also can be delivered quickly to suit your exact needs. Models with ½ NPT conduit fitting (PX509C) do not have a demountable termination and trim pots are an extra cost option.
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.

Recognized 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 PXM509-IS is also available in standard configurations, with ranges from 0-10 in H2O to 0-3500 psi ranges and standard threads. Please see PX509-IS for complete details, or contact our Pressure department for more information.
