VEGABAR 19 • Two-wire 4 … 20 mA

3 Product description

Measuring system

Fig. 3: Process pressure measurement VEGABAR 19

The process pressure acts on the piezoresisitve sensor element via the process diaphragm. The process pressure causes a resistance change which is converted into a corresponding output signal and output as measured value.

4.1 General instructions

The instrument is suitable for standard and extended ambient conditions acc. to DIN/EN/IEC/ANSI/ISA/UL/CSA 61010-1. It can be used indoors as well as outdoors.

Note:

For safety reasons, the instrument must only be operated within the permissible process conditions. You can find detailed information on the process conditions in chapter "

Technical data

" of the operating instructions or on the type label.

Hence make sure before mounting that all parts of the instrument exposed to the process are suitable for the existing process conditions.

These are mainly:

•

Active measuring component

Process fitting

Process seal

Process conditions in particular are:

•

Process pressure

Process temperature

Chemical properties of the medium

•

Abrasion and mechanical influences

The permissible process pressure range is specified by "MWP" (Maximum Working Pressure) on the type label, see chapter "

Structure

".

The MWP takes the element of the measuring cell and processing fitting combination with the weakest pressure into consideration and may applied permanently. The specification refers to a reference temperature of +20 °C (+68 °F). It also applies when a measuring cell with a higher measuring range than the permissible pressure range of the process fitting is installed order-related.

In order to prevent damage to the device, the test pressure may only exceed the specified MWP briefly by 1.5 times at reference temperature. The pressure stage of the process fitting as well as the overload resistance of the measuring cell are taken into consideration here

(see chapter "

Technical Data

").

In addition, a temperature derating of the process fitting, e. g. with flanges, can limit the permissible process pressure range according to the respective standard.

Protect your instrument against moisture ingress through the following measures:

•

Use a suitable connection cable (see chapter "

power supply

")

Connecting to

•

Tighten the cable gland or plug connector

Lead the connection cable downward in front of the cable entry or plug connector

Ventilation and pressure compensation

This applies mainly to outdoor installations, in areas where high humidity is expected (e.g. through cleaning processes) and on cooled or heated vessels.

Make sure that the degree of contamination specified in chapter

"

Technical data

" meets the existing ambient conditions.

Ventilation and pressure compensation for VEGABAR 19 are provided by an air-permeable, moisture-blocking filter element.

1

Fig. 6: Position of the filter element

1 Filter element

For effective ventilation, the filter element must always be free of buildup.

Caution:

Do not use a high-pressure cleaner. The filter element could be damaged, which would allow moisture into the housing.

Screwing in

On devices with a threaded fitting, the hexagon on the process fitting must be tightened with a suitable wrench.

See chapter "

Dimensions

" for wrench size.

Warning:

The housing or the electrical connection may not be used for screwing in! Depending on the device version, tightening can cause damage, e. g. to the rotation mechanism of the housing.

Process pressure range -

Mounting accessory

The permissible process pressure range is stated on the type label.

The instrument should only be operated with these pressures if the mounting accessory used also fulfils these values. This should be ensured by suitable flanges, welded sockets, tension rings with Clamp connections, sealings, etc.

Temperature limits

Higher process temperatures often mean also higher ambient temperatures. Make sure that the upper temperature limits stated in chapter "

Technical data

" for the environment of the electronics housing and connection cable are not exceeded.

5.1 Preparing the connection

Always keep in mind the following safety instructions:

•

Carry out electrical connection by trained, qualified personnel authorised by the plant operator

•

If overvoltage surges are expected, overvoltage arresters should be installed

Warning:

Only connect or disconnect in de-energized state.

The data for power supply are specified in chapter "

Technical data

".

Note:

Power the instrument via an energy-limited circuit (power max. 100 W) acc. to IEC 61010-1, e.g.

•

Class 2 power supply unit (acc. to UL1310)

SELV power supply unit (safety extra-low voltage) with suitable internal or external limitation of the output current

Keep in mind the following additional factors that influence the operating voltage:

•

Lower output voltage of the power supply unit under nominal load

(e.g. with a sensor current of 20.5 mA or 22 mA in case of fault)

•

Influence of additional instruments in the circuit (see load values in chapter "

Technical data

")

Use cable with round cross section. Depending on the plug connection, you have to select the outer diameter of the cable respectively so that the seal effect of the cable gland is ensured.

Depending on the connection method or signal output, the device is connected with standard two, three or four-wire cable without shielding.

6.1 Maintenance

If the device is used properly, no special maintenance is required in normal operation.

In some applications, product buildup on the diaphragm can influence the measuring result. Depending on the sensor and application, take precautions to ensure that heavy buildup, and especially a hardening thereof, is avoided.

The cleaning helps that the type label and markings on the instrument are visible.

Take note of the following:

•

Use only cleaning agents which do not corrode the housings, type

• label and seals

Use only cleaning methods corresponding to the housing protection rating

6.2 Rectify faults

The operator of the system is responsible for taking suitable measures to rectify faults.

The device offers maximum reliability. Nevertheless, faults can occur during operation. These may be caused by the following, e.g.:

•

Sensor

Process

•

Voltage supply

Signal processing

Fault rectification

Reaction after fault rectification

24 hour service hotline

The first measures are:

•

Evaluation of fault messages

Checking the output signal

Treatment of measurement errors

A smartphone/tablet with the adjustment app or a PC/notebook with the software PACTware and the suitable DTM offer you further comprehensive diagnostic possibilities. In many cases, the causes can be determined in this way and the faults eliminated.

Depending on the reason for the fault and the measures taken, the steps described in chapter "
