EL2600 Pressure Transmitter and 'U' Syphons
Description The EL2600 is a combined pressure sensor and transmitter which is designed for general and industrial use. It has a 2-wire 4-20 mA current loop, and a ¼" NPT process connection. Two syphon tube and valve assemblies are available, one with a maximum design pressure of 25 bar g, and one with a maximum design pressure of 80 bar g.
Limiting conditions Pressure/temperature limits EL2600
-30 °C (medium) -20 °C (ambient) 100 °C (medium) 80 °C (ambient)

If pressure peaks are likely to occur in your application, we recommend the use of a pressure snubber. Alternatively, a higher range pressure transmitter could be used, though this would mean some loss of signal resolution.

* No 'U' syphon is available for these ranges, therefore maximum operating temperature is limited to 100 °C
