2. Safety

WARNING!

Before installation, commissioning and operation, ensure that the

appropriate dierential pressure gauge has been selected in terms

of measuring range, design and specic measuring conditions.

Check the compatibility with the medium of the materials subjec-

ted to pressure!

In order to guarantee the measurement accuracy and long-term

stability specied, the corresponding load limits must be obser-

ved.

Only work on the gauge with the voltage disconnected.

Non-observance can result in serious injury and/or damage to the

equipment.

Further important safety instructions can be found in the individual

chapters of these operating instructions.

2.1 Intended use

The dierential pressure measuring instruments of the DELTA-line product family

are primarily used for the monitoring and control of low dierential pressures

where there are high requirements in terms of one-sided overpressure and static

pressure.

Typical markets for these products are the shipbuilding industry, process heating

technology, the heating, ventilation and air-conditioning industries, the water/

wastewater industry, and machine building and plant construction. For these, the

main function of the measuring instruments is the monitoring and control of lters,

compressors and pumps.

The instrument has been designed and built solely for the intended use described

here, and may only be used accordingly.

The manufacturer shall not be liable for claims of any type based on operation

contrary to the intended use.

2. Safety

2.2 Additional instructions for operation as a flow limiter in accordance

with VdTÜV code of practice “Flow 100:2006”

The maximum permissible electrical loads of 250 V AC / 1.4 A or 30 V DC / 0.4 A

must not be exceeded. For this reason, a fuse must be provided in the current

circuit with a rated value that is smaller than 0.6 times the maximum permissible

current values.

The safety function is that, on falling dierential pressure, the switch contact will

open when the set limit value is reached.

The requirements on the interlocking and unlocking, as stipulated in the VdTÜV

code of practice 'Flow 100:2006' for limiters of “special design”, must be ensured

by external measures.

The measuring arrangement must be designed in accordance with DIN 19216. For

this arrangement with block valves it must be ensured that the dierential pressure

line between the block valve and the dierential pressure sensor, as a constituent

element of the switching element, is at least 500 mm long.

The requirements on the dierential pressure lines in accordance with VdTÜV

code of practice “Flow 100:2006” section 5.7.2.3 must be met.

guration procedure.

2.3.12 Commissioning

All applications

The operability of the switching function of the DPGS40TA.100-xxS dierential

pressure gauge must be tested both during commissioning and at appropriate

intervals. Both the nature of the testing as well as the chosen intervals are the

responsibility of the user.

Additional for applications with low demand rate

The interval for the proof test usually conforms to the PFD

avg

value given in

the standard. Normally the proof test takes place every year, see certicates

V 495.01/15 and V 405.02/15.

2.3.13 Proof test of the safety function

Through a test of the entire safety function, check whether the switch is operating

correctly.

4. Design and function

4.1 Description

4. Design and function

Pressures p

1

and p

2

act on the media chambers ⊕ and ⊖, which are separated by

an elastic diaphragm (1).

The dierential pressure (∆p = p

1

- p

2

) leads to an axial deection of the dia-

phragm against the measuring range springs (2).

The deection, which is proportional to the dierential pressure, is transmitted to

the movement (4) in the indicating case and to the leaf springs of the micro swit-

ches (5) via a pressure-tight and low friction rocker arm (3).

Overpressure safety is provided by metal bolsters (6) resting against the elastic

diaphragm.

The setting of the switch point is made by the adjustment screws accessible from

the front (7). The assistant scales (8) simplify the setting of the switch points.

Prior to the installation of the instrument, clean the measuring lines thoroughly

by tapping and blowing or ushing.

■

Protect measuring instruments from contamination and high temperature

changes!

■

The pressure gauge must be mounted free from vibration and should be

aligned so that it is easy to read. It is recommended that an isolation device is

interposed between the pressure tapping point and the instrument, which will

enable the replacement of the instrument and a zero point check while the plant

is running. The instruments should be protected against coarse dirt and wide

uctuations in ambient temperature.

■

For sealing the connections, use at gaskets, lens-type sealing rings or WIKA

prole sealings. In order to orientate the gauge so that the on-site display can

be read as well as possible, a connection with clamp socket or union nut should

be used. When screwing on and unscrewing the instruments they should not be

gripped by the case, but rather only on the spanner ats of the connection!
