Intrinsically safe pressure transmitter with ceramic diaphragm for trichloroethylene compatibility. Ideal for low-pressure measurement in hazardous areas.
This configuraton of the DMK351 low-range pressure transmitter has been selected for applications involving aggressive media like Trichloroethylene, where compatibility and corrosion resistance are critical. Its ceramic diaphragm, constructed from 96% Alumina Al2O3, offers exceptional resistance to a wide range of chemicals, ensuring long-term stability and accuracy in demanding environments. This makes it ideal for processes where traditional stainless steel diaphragms might be susceptible to corrosion or damage.
This intrinsically safe pressure transmitter is certified for use in hazardous areas, making it suitable for applications where flammable or explosive vapors, like Trichloroethylene, may be present. The certification ensures that the device operates safely and won’t ignite the surrounding atmosphere. This is particularly important in industries like chemical processing, pharmaceuticals, and oil and gas, where safety is paramount.
This DMK351 pressure transmitter also incorporates FFKM seals on the measurement side, which is a critical feature when dealing with aggressive chemicals like Trichloroethylene. FFKM, also known as perfluoroelastomer, is a high-performance fluorocarbon elastomer that offers exceptional chemical resistance and thermal stability.
The choice of FFKM for the seals is particularly important in this application because Trichloroethylene can degrade or swell many common sealing materials. This can lead to leaks, inaccurate measurements, and even sensor failure. FFKM, however, is virtually inert to Trichloroethylene and a wide range of other chemicals, ensuring the integrity and longevity of the pressure transmitter.
With a measurement range of 0 to 100 mbarg and a 4-20mA output signal, the DMK351 is well-suited for low-pressure applications involving Trichloroethylene. This could include monitoring vapor pressure in storage tanks, controlling flow rates in pipelines, or ensuring accurate dosing in chemical reactions. The 1/2 inch NPT male process connection provides a reliable and leak-free seal, further enhancing the transmitter’s suitability for these applications.
The DMK351‘s robust design and construction, coupled with its intrinsically safe certification and specialized features, make it a valuable tool for engineers and technicians working with Trichloroethylene. Whether it’s in a research laboratory, a chemical processing plant, or an oil refinery, this pressure transmitter offers a reliable and accurate solution for low-pressure measurement in demanding applications.
