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 1⁄4" 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.

Note: High pressure 'spikes' above maximum overpressure, even

of very short (milli-seconds) duration, could damage sensors. 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.

Process connection

For fluids below 100°C the EL2600 may be mounted directly via its

1⁄4" NPT connection.

Above 100°C, a 'U' syphon and isolating valve must be fitted

between the EL2600 and the vessel or pipeline.
