| Feature: |
| The Series 636D Differential Pressure Transmitter can be used for measuring pressures of liquids, gases, & vapours. All available ranges have an excellent 0.5% F.S. accuracy with a 4- 20 mA output standard or optional 1-5 VDC output. The NEMA 4 housing is an all 316 welded construction that is designed to withstand the harshest environmental conditions. With all 316L wetted materials this transmitter is compatible with most media. These units are CSA approved explosion-proof for use in the specified hazardous locations and meet NACE standards for off-shore applications. |
