Description
Dwyer Series 628 INDUSTRIAL PRESSURE TRANSMITTER
The Series 628 Pressure Transmitters are 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 gage pressure ranges with a variety of optional outputs, process connections and electrical terminations to allow you to select the right transmitter for your application.
Applications:
- Compressors
- Pumping Systems
- Irrigation System Pressure
- Industrial Process Monitoring
- Hydraulic
Features:
- Robust 316L SS oil filled sensor provides shock and vibration resistance insuring stability in controlling pressure for process applications
- NEMA 4X rated enclosure provides protection in harsh environments permitting outdoor monitoring or in areas where dust and particulate matter exists
- A wide range of models and connections that can meet pressure measurement specifications from low to very high
