4. Design and function

Description

Pressures p by the magnetic piston under pressure(or magnetic piston and separating

diaphragm for model 700.02).

and p2 are given in the ⊕ and ⊖ measuring chambers, separated

The dierence in pressure causes an axial movement (deection) of the piston supported by the compression spring.

The deection resulting from this is taken up by a ring magnet found on the instrument pointer and appropriately displayed. This design combines the advantages of complete separation of the measuring system and the indication while eliminating any leakage to the exterior.

For model 700.01 the volume ow from the ⊕ measuring chamber to the ⊖ measuring chamber is minimised by the constructive design and will not interfere with standard processes. These instruments are mainly intended for gas/air supply and preparation applications where no magnetic particles are involved.

5. Options and accessories

In processes with oating particles model 700.02 should be used.

Scope of delivery

Cross-check the scope of delivery with the delivery note.

5. Options and accessories

5.1 Mounting ange (only for model 700.01, see left illustration) May be retrotted on site as required. Alignment of the front bezel (A) by means of the stamped cams to the grooves found on the case circumference. Push front bezel on the case until it snaps into

position.

5.2 Minimum or maximum drag pointer (see illustrations) The drag pointer (B) serves to monitor and control the miniumum or maximum occurring dierential pressure.

5.3 Reed contact model 851.3 and 851.3.3 (see illustrations) May be retrotted and adjusted on site as required. Fastening is by means of two screws (D) integrated in the reed case (C) on the display case with the pertinent female thread.

6. Transport, packaging and storage

5.1 Transport

Check pressure gauge for any damage that may have been caused by transport. Obvious damage must be reported immediately.

6.2 Packaging

Do not remove packaging until just before mounting. Keep the packaging as it will provide optimum protection during transport (e.g. change in installation site, sending for repair).

6.3 Storage

Permissible conditions at the place of storage:

Storage temperature: -20 ... +70 °C (optional: -40 … +70 °C)

7. Commissioning, operation

Mechanical connection

The installation of the dierential pressure gauge is made following the installation recommendations for pressure gauges in accordance with EN 837-2 /7.

Mounting of the process connection according to axed symbols ⊕ and ⊖ ⊕ high pressure, ⊖ low pressure

■

Hold against the connection pieces in the case of installation by means of 17 mm screw spanner (installation without holding against the connection pieces may cause thet measuring system to get loose).

■

The maximum permissible medium/ambient temperature must not be exceeded

■

Prior to the installation of the pressure gauge, clean the measuring lines thoroughly by tapping and blowing or rinsing

■

Mount and operate the measuring instruments free from vibration

■

Protect measuring instruments from contamination and high temperature changes

To avoid foreign matter in the measuring system and the resulting damage to the system, the pressure gauge must be mounted above the connector. For measuring media containing suspended particles model 700.02 should be used.

7. Commissioning, operation

Switch point adjustment

Preference should be given to setting the switch point before installing the measuring instrument. The necessary test path is generated manually (e.g. by means of an antimagnetic screwdriver).

Manual test path generation

Plus media chamber

antimagnetic

The switch point can also be set in a pressurised condition after installation. The switch points are set at the factory when the set points are given. The switch point is adjusted by turning the contact adjustment screws on the outside of the reed case.

Anticlockwise rotation: Switch point can be moved in the direction of the start of the measuring range

Clockwise rotation: Switch point can be moved in the direction of the end of the measuring range

Zero point check

In general, the zero point should only be checked and adjusted at zero pressure. The system fastening lug on the back of the case can be easily slackened o for zero point correction of the pressure gauge. Now the zero point can be readjusted by moving the measuring system to the right or left. After this has been done the measuring system is to be secured again with the mounting screw (recommended tightening torque of the mounting screw 1.3 Nm).

8. Maintenance and cleaning

8.1 Maintenance

The instruments are maintenance-free.

The dierential pressure gauges with piston oer long service life provided they are handled and operated properly.

Checks should be carried out on a regular basis to ensure the measuring accuracy of the pressure gauge.

Repairs must only be carried out by the manufacturer or appropriately qualied skilled personnel.

8.2 Cleaning

CAUTION!

■

Clean the pressure gauge with a moist cloth.

■

Wash or clean the dismounted pressure gauge before returning it, in order to protect persons and the environment from exposure to residual media.

9. Dismounting and disposal

WARNING!

Residual media in dismounted pressure gauges can result in a risk to persons, the environment and equipment. Take sucient

precautionary measures.

9.1 Dismounting

Only disconnect the pressure gauge once the system has been depressurised!

9.2 Disposal

Incorrect disposal can put the environment at risk.

Dispose of instrument components and packaging materials in an environmentally compatible way and in accordance with the country-specic waste disposal regulations.
