Mounting

Mounting and safety instructions

• NOTE – Do not remove the packaging or protective caps of the device until shortly before the mounting procedure, to exclude any damage to the diaphragm and the threads! Protective caps must be kept! Dispose of the packaging properly!
• NOTE – If there is increased risk of damage to the device by lightning strike or overvoltage, increased lightning protection must additionally be provided!
• NOTE – Treat any unprotected diaphragm with utmost care; this can be damaged very easily.
• NOTE – Provide a cooling line when using the device in steam piping and clarify the material compatibility.
• NOTE – The measuring point must be designed in such a way that cavitation and pressure surges are avoided.
• NOTE – When installing the device, avoid high mechanical stresses on the pressure port! This will result in a shift of the characteristic curve or to damage, in case of very small pressure ranges and devices with a pressure connection/port made of plastic.
• NOTE – In hydraulic systems, arrange the device such that the pressure port points upwards. (venting)
• NOTE – If the device is installed with the pressure port pointing upwards, ensure that no liquid drains off on the device. This could result in humidity and dirt blocking the gauge reference in the housing and could lead to malfunctions. If necessary, dust and dirt must be removed from the edge of the screwed joint of the electrical connection.
• NOTE – The permissible tightening torque depends on the conditions on site (material and geometry of the mounting point). The specified tightening torques for the pressure transmitter must not be exceeded!
• NOTES – for mounting outdoors or in a moist environment:
  • Please note that your application does not show a dew point, which causes condensation and can damage the pressure transmitter. There are specially protected pressure transmitters for these operating conditions. Please contact us in such case.
  • Connect the device electrically straightaway after mounting or prevent moisture penetration, e.g. by a suitable protective cap. (The ingress protection specified in the data sheet applies to the connected device.)
  • Select the mounting position such that splashed and condensed water can drain off. Stationary liquid on sealing surfaces must be excluded!
  • If the device has a cable outlet, the outgoing cable must be routed downwards. If the cable needs to be routed upwards, this must be done in an initially downward curve.
  • Mount the device such that it is protected from direct solar radiation. In the most unfavourable case, direct solar radiation leads to the exceeding of the permissible operating temperature.
  • A device with gauge reference in the housing (small hole next to the electrical connection) must be mounted such that the gauge reference is protected against dirt and humidity. If the transducer is exposed to liquid admission, the gauge reference will be blocked, and the equalization of air pressure will be prevented. In this condition, a precise measurement is impossible and damage to the transducer may occur.

Conditions for devices with 3-A symbol
The device or its connecting piece must be installed in such a way that the surfaces are self-draining (permissible installation position 273° … 87°).
Make sure that the welding socket is mounted flush inside the tank. The user is responsible for:

• the correct size of the seal and the choice of an elastomeric sealing material that complies with the 3- A standard
• an easy to clean installation position of the pressure transmitter with little dead space, as well as definition / verification / validation of a suitable cleaning process   defining adequate service intervals

Conditions for devices, with EHEDG certificate
Install the device according to the requirements given in EHEDG Guidelines 8, 10 and 37. That is to mount the device in a self-draining orientation. The device should be installed flush to the process area. If mounting in a T-piece, the ratio between the depth of the upstand (L) and the diameter (D) of the upstand shall be L/D<1. If welded adapters are used, the food contact surface must be smooth, and the welding has to be done according to EHEDG Guideline 9 and 35. Suitable pipe couplings and process connections must be applied according to the EHEDG Position Paper. (List the available ones.)

Mounting steps for connections according to DIN 3852

NOTE -Do not use any additional sealing material such as tow, hemp or Teflon tape!

• The O-ring is undamaged and seated in the designated groove.
• The sealing face of the mating component has a flawless surface. (RZ 3.2)
  1. Screw the device into the corresponding thread by hand.
  2. Devices equipped with a knurled ring: only tighten by hand
  3. Devices with a wrench flat must be tightened using a suitable open-end wrench. Permissible tightening torques for pressure transmitter:
• wrench flat made of steel:
  • G1/2″: approx. 10 Nm
  • G1″: approx. 20 Nm
  • G1 1/2″: approx. 25 Nm
• wrench flat made of plastic: max. 3 Nm

Mounting steps for G1″ cone connection

1. Screw the device into the mating thread by hand (seal produced metallically)
2. Then tighten it using an open-end wrench. Permissible tightening torques for pressure transmitter: pN < 10 bar: 30 Nm; pN ≥ 10 bar: 60 Nm

Mounting steps for dairy pipe connections

• The O-ring is undamaged and seated in the designated groove.
• Chapter “3.2 and/or 3.3” have been noticed. EHEDG conformity is only ensured in combination with an approved seal for codes M73, M75, M76. This is e.g.: ASEPTO-STAR k-flex upgrade seal by Kieselmann GmbH
  1. Centre the dairy pipe connection in the counterpart.
  2. Screw the cup nut onto the mounting part.
  3. Then tighten it using a hook wrench.

Mounting steps for Clamp and Varicent connections

• A suitable seal for the measured fluid and the pressure to be measured is available.

• Chapter “3.2 and/or 3.3” have been noticed. EHEDG conformity is only ensured in combination with an approved seal. This is e.g.:
  for Clamp connections – codes C61, C62, C63: T-ring seal from Combifit International B.V. for Varivent connections – codes P40, P41: EPDM-O-ring which is FDA-listed Note, that P40 can only be used for tank flanges.

  1. Place the seal onto the corresponding mounting part.
  2. Centre the Clamp connection or Varivent connection above the counterpart with seal.
  3. Then fit the device with a suitable fastening element (e. g. semi-ring or retractable ring clamp) according to the supplier’s instructions.

Mounting steps for DRD and flange connections

• A suitable seal for the measured fluid and the pressure to be measured is available. (e.g. a fiber seal)
  1. Put the seal between the connecting flange and counter flange
  2. Install the device with 4 resp. 8 screws (depending on the flange version) on the counter flange.

Orientation of the display and operating module
The display and operating module can be rotated continuously so as to guarantee easy readability even in unusual mounting positions. Proceed as follows to change the position:

• Unscrew the metal cap by hand.
• Rotate the display and operating module carefully by hand into the desired position. The module is equipped with a turning limiter.
• Before screwing on the cap again, the o-ring and sealing surfaces of the housing have to be checked for damage and if necessary, have to be changed!
• Afterwards screw the metal cap on by hand and make sure that the housing is firmly locked again.

NOTE – Ensure that moisture cannot enter the device! The seals and sealing surfaces must not get dirty, as (depending on application and location) fouling can cause a reduced degree of protection and therefore lead to device failure or irreparable damage to the device.
