General Information
1.1.
Object and purpose
The sensor adaptor will be the linking element between a flow meter and an encapsulated flameproof electronic.
(EXd)
A flow meter can be a gear meter, helical gear meter, turbines or others. Those have a sensor hole or a thread
sleeve like it is defined in this document or mentioned in the attached drawings.
The electronic can be any indicating device like a FlowPod or a junction box that encloses additional electronics
to evaluate the signals from the sensor coil.
The sensor coil can be a carrier frequency or an inductive one. Both are described in this document.
Typical applications are marine applications on ships or oil and gas applications.

General Safety
Following these instructions is mandatory:
Any responsibility is lapsed if the instructions and procedures as described in this manual are not followed.
LIFE SUPPORT APPLICATIONS: The SV-sensor-adaptor is not designed for use in life support appliances,
devices or systems where malfunction of the product can reasonably be expected to result in a personal injury.
Customers using or selling these products for use in such applications do so at their own risk and agree to fully
indemnify the manufacturer and supplier for any damages resulting from such improper use or sale.
Electrostatic discharge does inflict irreparable damage to electronics! Before installing or opening the unit, the
installer has to be discharged by touching a well-grounded object.
This unit must be installed in accordance with the EMC (Electro Magnetic Compatibility) guidelines.
Do connect a proper grounding to the aluminum/stainless steel casing as indicated if the SV**-****-****-** is
used on a ship, truck or other application, where the object is not sufficiently grounded.
When assembling the equipment, applicable national standards and installation regulations must be observed.
Sensor holes, into which line bushings are screwed, must meet the minimum requirements of IEC/EN 60079-1,
section 5.3 (Table 4). Observe the minimum depth of engagement. This requires comparing the length of the
thread in the line bushing with the minimum depths of engagement in IEC/EN 60079-1. A threading length which
is longer or equal to the lengths specified in IEC/EN 60079-1 must be selected.
