3.4 Installation steps for EN 837

- Use a suitable seal, corresponding to the medium and the

pressure input (e. g. a cooper gasket).

- Ensure that the sealing surface of the taking part is per-

fectly smooth and clean. (R

6.3)

- Screw the device into the corresponding thread by hand.

- Tighten it with a wrench (for G1/4": approx. 20 Nm; for

G1/2": approx. 50 Nm).

- The indicated tightening torques must not be

exceeded!

- Note: permitted pressure ranges according to

EN 837!

3.5 Installation steps for NPT

- Use a suitable seal (e. g. a PTFE-strip).

- Screw the device into the corresponding thread by hand.

- Tighten it with a wrench (for 1/4" NPT: approx. 30 Nm; for

1/2" NPT: approx. 70 Nm).

- The indicated tightening torques must not be

exceeded!

3.6 Installation steps for flare

- Cut the end at right angle to the piping and remove all

internal and external burrs.

- Make the flare; depending on the usage, the device has

to be tightened with max. 10 Nm.

- The indicated tightening torques must not be

exceeded!

3.7 Installation steps for internal threads M20x1.5 and

9/16" UNF (for DMP 334)

- Screw the high pressure connection into the internal

thread of the DMP 334 and tighten it properly with approx.

160 Nm.

DANGER! The high pressure tube seals metal-to-

metal in the chamfer of the pressure port. No fur-

ther seal is allowed with this high pressure con-

nection. A wrong installation can cause enor-

mous danger!

3.8 Installation steps for dairy pipe

- Check to ensure that the O-ring fits properly into the in-

tended groove in the mounting part.

- Center the dairy pipe connection in the counterpart.

- Screw the cup nut onto the mounting part.

- Then tighten it with a hook wrench.

3.9 Installation steps for Clamp and Varivent

- Use a suitable seal corresponding to the medium and the

pressure input.

- Put the seal onto the corresponding mounting part.



- Center the Clamp or Varivent

connection on the fitting

counterpart with seal.

- Then fit the device with a suitable fastening element (e. g.

semi-ring or retractable ring clamp) according to the sup-

plier's instructions.

3.10 Installation steps for connecting flanges

- Use a suitable seal corresponding to the medium and

pressure input. (e. g. a fiber gasket).

- Put the seal between connecting flange and counter

flange.

- Install the device with 4 resp. 8 screws (depending on

flange version) on the counter flange.

For devices with cable gland as well as cable socket, you

have to make sure that the external diameter of the used

cable is within the allowed clamping range. Moreover you

have to ensure that it lies in the cable gland firmly and

cleftlessly!

For the installation of a device with cable outlet following

bending radiuses have to be complied with:

cable without ventilation tube:

static installation :

dynamic application: 10-fold cable diameter

cable with ventilation tube:

static installation :

dynamic application: 20-fold cable diameter

Please note for devices with ISO 4400 or Buccaneer plug,

that the cable socket has to be mounted properly to

ensure the ingress protection mentioned in the data

sheet. Please check if the delivered seal is placed

between plug and cable socket. After connecting the

cable fasten the cable socket on the device by using the

screw.

On devices with field housings, the terminal clamps are

situated under the metal cap. To install the device

electrically, the cap must be screwed off. Before the cover

is screwed on again, the O-ring and the sealing surface

on the housing have to be checked for damages and if

necessary to be changed! Afterwards screw the metal cap

on by hand and make sure that the field housing is firmly

locked again.

Prevent the damage or removal of the PTFE filter which



is fixed over the end of the air tube on devices with cable

outlet and integrated air tube.

For the electrical connection a shielded and twisted

multicore cable is recommended.

If a transition is desired from a transmitter cable with

gauge tube to a cable without gauge tube, we recommend

our terminal box KL 1 or KL 2.

5. Initial start-up

WARNING! Before start-up, the user has to check for

proper installation and for any visible defects.

WARNING! The device can be started and operated by

authorized personnel only, who have read and under-

stood the operating manual!

WARNING! The device has to be used within the tech-

nical specifications, only! (compare the data in the data

sheet)

The transmitter shall be supplied by Limited Energy

Source (per UL 61010) or NEC Class 2 Power Source.

Devices with an accuracy of 0.1 % FSO have micro-

controlled electronics for processing and improving the

signal. Principally, the processing takes more time as for

analogue sensors, which have only an amplifier. Due to

this longer response time, the output signal follows the

measured value discontinuously. For nearly stable

measured values, this characteristic is secondary. Please

compare the specification of the response time in the data

sheet.

Intelligent

devices

interfaces can also be configured by these electronics.

Offset, span and damping are programmable within the

limits given in the data sheet. For configuring the device,

the programming kit CIS 510 consisting of Adapt 1, Win-

dows



compatible

P-Scale 510, power supply and connecting cable is nec-

essary. This can be ordered additionally from BD SEN-

SORS.

6. Placing out of service

WARNING! Disassemble the device only in current and

pressure less condition! Check before disassembly, if it is

necessary to drained off the media before dismantling!

WARNING! Depending on the medium, it may cause dan-

ger for the user. Comply therefore with adequate precau-

tions for purification.

7. Maintenance

In principle, this device is maintenance-free. If desired, the

housing of the device can be cleaned using a damp cloth and

non-aggressive cleaning solutions, in switched-off state.

With certain media, however, the diaphragm may be polluted

or coated with deposit. It is recommended to define corre-

sponding service intervals for control. After placing the device

out of service correctly, the diaphragm can usually be cleaned

carefully with a non-aggressive cleaning solution and a soft

brush or sponge. If the diaphragm is calcified, it is recom-

mended to send the device to BD SENSORS for decalcifica-

tion. Please note the chapter "Service/Repair" below.

A false cleaning of the device can cause an irreparable

damage on the diaphragm. Therefore never use pointed

objects or pressured air for cleaning the diaphragm.

8. Service / Repair

8.1Recalibration

During the life-time of a transmitter, the value of offset and

span may shift. As a consequence, a deviating signal value in

reference to the nominal pressure range starting point or end

point may be transmitted. If one of these two phenomena oc-

curs after prolonged use, a recalibration is recommended to

ensure furthermore high accuracy.

8.2 Return

Before every return of your device, whether for recalibration,

decalcification, modifications or repair, it has to be cleaned

carefully and packed shatter-proofed. You have to enclose a

notice of return with detailed defect description when sending

the device. If your device came in contact with harmful

substances, a declaration of decontamination is additionally

required. Appropriate forms can be downloaded from our

homepage www.bdsensors.com. Should you dispatch a

device without a declaration of decontamination and if there

are any doubts in our service department regarding the used

medium, repair will not be started until an acceptable

declaration is sent.

If the device came in contact with hazardous

substances, certain precautions have to be

complied with for purification!

9. Disposal

The device has to be disposed of according to the

European

Directives

2003/108/EG (on waste electrical and electronic

equipment). It is prohibited to place electrical and

electronic equipment in domestic refuse!

WARNING! Depending on the used medium, deposit on

the device may cause danger for the user and the envi-

ronment. Comply with adequate precautions for purifica-

tion and dispose of it properly.

10. Warranty conditions

The warranty conditions are subject to the legal warranty pe-

riod of 24 months from the date of delivery. In case of improper



use, modifications of or damages to the device, we do not ac-
