7.1.2
Processing Note for Sticking
The provided sticky tapes stick well on clean, dry and plain surfaces. The worse the pollution at the place of
instalment, the better the sticky tapes should be. A surface roughness of R
recommendable. Typical solvent for cleaning surfaces are a 50/50 - isopropyl-alcohol / water mixture or
heptane. The surfaces of materials as copper, brass etc. should be sealed to avoid an oxidation. The stability
of the adhesion is directly depending on the contact, which the adhesive develops to the stuck surfaces. A
high pressure results in a good surface contact.
The optimal sticking temperature is between + 21 °C and 38 °C.
Avoid colder sticking surfaces than + 10 °C, because in this case the adhesive becomes too hard and
perhaps a sufficient immediate adhesion is hardly to achieve. After proper sticking the stability of the
connection is ensured, also when the temperature is below zero. The final tackiness of a sticking is from
experience reached after approximately 72 hours (at + 21 °C). For sticking use only the provided sticky tape.

Resistance to Chemicals of the Magnetic Tape
Chemicals that show little or no impact after 2-5 years when contacting permanently:
- Formic acid
- cotton oil
- Formaldehyde 40%
Chemicals that show weak to moderate effects after 1 year when contacting permanently:
- Acetone
- Kerosene
- Seawater
Chemicals that show a strong impact after 1-5 month when contacting permanently:
- Benzene
- Carbon tetrachloride
- Tetrahydrofuran
7.1.4
Sticking and Cutting
NOTE!
When sticking the magnetic tape pay attention to the marks on the
magnetic tape and on the sensor head. A faulty installation delivers
incorrect values. An already stuck magnetic tape is ruined after
removing and can't be used again. Observe also the counting
direction of the measuring system.
The magnetic tape and the covering band must be cut to the exact
length before sticking.
Magnetic tape length = measuring length + Sensor length
Preferably the magnetic tape should be stuck into a nut or aligned to an edge.
Procedure for sticking: The magnetic tape is already factory bonded with the steel band, in between is a
double sided sticky tape. Stick the provided sticky tape onto the carrier side (= steel band).
Now adjust the magnetic tape and stick it onto the surface. The best way to stick the magnetic tape is to do it
in two steps. Remove the first half of the adhesive film from the sticky tape and stick it, then do the rest
length.
Then stick the sticky tape onto the covering band. It is not important on which side of the covering band the
sticky tape is stuck on. Stick the covering band onto the visible brown magnetized synthetic tape.
