CONTROLS

Differentian pressure transmitters 0...2.5 bar

Function:

Monitoring differential gaseous pressure, non-aggressive media.

Possible areas of applications are:

- air-conditioning and clean rooms;

- building automation;

- valve and flap control;

- fluid and level monitoring;

- control of air flows.

Transduction in voltage and current values.

Each transmitter can be set with two pressure ranges using the jumper

"Range".The factory setting is for range I (jumper inserted).

To choose range 2, remove the jumper

The response time of output signal can be configured.

The factory setting is for slow response I s (useful for suppressing pressu-

re peaks), jumper "Response inserted".To increase fast response remove

the jumper

The output level of 3- wire models can be configured in 0... I OVdc (factory

setting, jumper "Output" inserted) or 4...20 mA by removing this jumper
