Cảm biến áp suất nước 628 series

The Series 626 Industrial Pressure Transmitterspossess a highly precise 0.25% full scale accuracy piezo-resistive sensor contained in a compact, rugged, NEMA 4X (IP66) stainless steel general purpose housing or cast aluminum conduit housing. he Series628 Industrial Pressure Transmittersare ideal for OEMs with 1% full scale accuracy sensors. The corrosion resistant 316L stainless steel wetted parts allow the Series 626 and 628 transmitters to measure the pressure in a multitude of processes from hydraulic oils to chemicals. The Series 626 and 628 are available in absolute and pressure ranges with a variety of optional outputs, process connections and electrical terminations to allow you to select the right transmitter for your application.

FEATURES/BENEFITS
• NEMA 4X rated enclosure provides protection in harsh environments permitting outdoor monitoring or in areas where dust and particulate matter exists
• Robust 316 SS oil filled sensor provides shock and vibration resistance insuring stability in controlling pressure for process applications
• A wide range of models and connections that can meet pressure measurement specifications from low to very high

APPLICATIONS
• Compressors
• Pumping systems
• Irrigation equipment
• Hydraulic
• Industrial process monitoring
