FL Series Flush Industrial Pressure Transmitter

0-50 through 0-7,500 psi

“Non-Oil Filled” Flush Diaphragm Sensor

Mechanically Isolated Sensor for Low Clamping Effect

Designed for the highest system integrity

Dylix’s FL Series Pressure Transmitter is designed for the OEM and end user where ruggedness, high performance, and reliability are required at a competitive price. Key feature of the FL is its non oil –filled sensing element. The sensing diaphragm is machined from a solid piece of steel, and can withstand the most abrasive / cyclical applications.

Manufactured for extended life cycles

Dylix’s engineers developed this product to last in high cyclical environments with or without the presence of waterhammeringor spiking. Advanced manufacturing techniques, extreme environmental burn-in and thorough residual stress relieving procedures ensure the FL Series maintains its performance over time.
