To measure the output signal and configure / calibrate the pressure transmitter, an ampere meter must be connected directly to the output circuit. The lower and upper range values can be set via a pushbutton on the electronic unit. An optional fastener is available for attaching a stainless steel tag so that the measuring points can be indicated.
Mounting Pressure transmitter The pressure transmitter can be connected directly to the shut-off valve. An angle bracket for wall or pipe mounting (2" Before installing the transmitter, check whether the device pipe) is also available as an accessory. design meets the requirements of the measuring point from a The pressure transmitter should be installed so that the measurement technology and safety specifications point of display and control unit are accessible during installation and...
Sealing and screw connections Moisture Connecting G ½ B spigot: Use suitable cables and tighten cable glands securely. The For sealing, a flat gasket must be used in accordance with DIN transmitter can also be protected against the ingress of EN 837-1.
Measuring pipe In order for the pipes to be laid correctly, the following points must be observed: — Keep the measuring pipe as short as possible and avoid sharp bends. — Lay the measuring pipe in such a way that no deposits can accumulate in it.
Electrical connections Cable connection Depending on the model supplied, the electrical connection is established via cable gland M16x1.5 (for diameters of WARNING – Electrical dangers! 5 to 10 mm) or M20x1.5 (for diameters of 6 to 11 mm), a Observe the applicable regulations governing threaded bore for cable gland 1/2-14 NPT, or via the Han 8U electrical installation.

Commissioning Output signal If the applied pressure is within the values indicated on the name plate, the output current ranges between 4 und 20 mA. General remarks If the pressure applied falls outside the set range, the output Once the pressure transmitter has been installed, it is put into current will be between 3.5 mA and 4 mA if the range is operation by switching on the operating voltage.
Adjusting lower range value / oblique sensor Correction procedure "A" described above does not affect the physical pressure shown; it only corrects the analog output During installation of the transmitter, zero position shifts may signal. For this reason, the analog output signal may differ occur due to the mounting position;...
Installing/Removing the LCD indicator 3. No tools are required to insert the LCD indicator. Carefully insert both guide pins for the LCD indicator in the guide holes of the transmitter inset. Make sure the black connection socket fits into the terminal on the transmitter inset.
Pressure sensor ventilation M10695 Fig. 15: Ventilation unit For technical reasons, you must apply atmospheric pressure to the reference side of the pressure sensor. A special ventilation unit (1) is screwed into the electronic housing from the outside and is equipped with a PTFE filter on the inside.
