1 OPL: The OPL (over pressure limit = sensor overload limit) for the measuring device depends on the lowest-

rated element, with regard to pressure, of the selected components, i.e. the process connection has to be taken

into consideration in addition to the measuring cell. Observe pressure-temperature dependency. The OPL may

only be applied for a short period of time.

2 MWP: The MWP (maximum working pressure) for the sensors depends on the lowest-rated element, with

regard to pressure, of the selected components, i.e. the process connection has to be taken into consideration

in addition to the measuring cell. Observe pressure-temperature dependency. The maximum working pressure

may be applied at the device for an unlimited period. The MWP can be found on the nameplate.

3 The maximum sensor measuring range corresponds to the span between the LRL and URL. This sensor

measuring range is equivalent to the maximum calibratable/adjustable span.

4 The calibrated/adjusted span corresponds to the span between the LRV and URV. Factory setting: 0 to URL.

Other calibrated spans can be ordered as customized spans.

Example

• Sensor: 10 bar (150 psi)

• Upper range limit (URL) = 10 bar (150 psi)

Turn down (TD):

• Calibrated/adjusted span: 0 to 5 bar (0 to 75 psi)

• Lower range value (LRV) = 0 bar (0 psi)

• Upper range value (URV) = 5 bar (75 psi)

TD = URL

TD = 10 bar (150 psi) = 2

|5 bar (75 psi) - 0 bar (0 psi)|

In this example, the TD is 2:1.

This span is based on the zero point.

3.2.1 Calculating the pressure

Devices with metallic process isolating diaphragm

The process pressure deflects the metal process isolating diaphragm of the sensor and a fill

fluid transfers the pressure to a Wheatstone bridge (semiconductor technology). The

pressure-dependent change in the bridge output voltage is measured and evaluated.

5 Installation

5.1 Mounting requirements

• Moisture must not penetrate the housing when the device is being mounted, the

electrical connection is being set up or during operation.

• Do not clean or touch process isolating diaphragms with hard and/or pointed objects.

• Do not remove the protection on the process membrane until just before installation.

• Always tighten the cable entry firmly.

• Point the cable and plug downwards where possible to prevent moisture from entering

(e.g. rain or condensation water).

• Protect the housing against impact.

• For devices with gauge pressure sensor, the following applies:

NOTICE

If a heated device is cooled during a cleaning process (e.g. by cold water), a vacuum

develops for a short time and, as a result, moisture can enter the sensor through the

pressure compensation element (1).

Device could be destroyed!

‣In the event of this happening, mount the device in such a way that the pressure

compensation element (1) is pointing downwards at an angle or to the side, if possible.

A0022252

5.2 Influence of the installation position

Any orientation is possible. However, the orientation may cause a zero point shift, i.e. the

measured value does not show zero when the vessel is empty or partially full.

6.1 Connecting the measuring unit

6.1.1 Terminal assignment

LWARNING

Risk of injury from the uncontrolled activation of processes!

‣Switch off the supply voltage before connecting the device.

‣Make sure that downstream processes are not started unintentionally.

LWARNING

An incorrect connection compromises electrical safety!

‣In accordance with IEC/EN 61010, a suitable circuit breaker must be provided for the

device.

‣Non-hazardous area: To meet device safety specifications according to the IEC/EN

61010 standard, the installation must ensure that the maximum current is limited to

500 mA.

‣Protective circuits against reverse polarity are integrated.

NOTICE

Damage to analog input of PLC resulting from incorrect connection

‣Do not connect the active PNP switch output of the device to the 4 to 20 mA input of a

PLC.

Connect the device in the following order:

1. Check whether the supply voltage matches the supply voltage indicated on the

nameplate.

2. Connect the device as indicated in the following diagram.
