INSTALLATION
General
NOTE
The installation carried out in hazardous areas should follow the recommendations of the IEC60079-14 standard.
NOTE
See appendix “A” Hazardous Area Certifications.
The overall accuracy of measurement and control depends on several variables. Although the
converter has an outstanding performance, proper installation is essential, in order to maximize its
performance.
Among all factors, which may affect converter accuracy environmental conditions are the most
difficult to control. There are, however, ways of reducing the effects of temperature, humidity and
vibration.
In warm environments, the transmitter should be installed to avoid, as much as possible, direct
exposure to the sun. Installation close to lines and vessels subjected to high temperatures should
also be avoided. Use of sun shades or heat shields to protect the transmitter from external heat
sources should be considered, if necessary.
Humidity is fatal to electronic circuits. In areas subjected to high relative humidity, the o-rings for the
electronics cover must be correctly placed. Removal of the electronics cover in the field should be
reduced to the minimum necessary, since each time it is re-moved, the circuits are exposed to the
humidity.
The electronic circuit is protected by a humidity proof coating, but frequent exposures to humidity
may affect the protection provided. It is also important to keep the covers tightened in place. Every
time they are removed, the threads are exposed to corrosion, since these parts cannot be protected
by painting. Code approved sealing methods on conduit entering the transmitter should be
employed.
Although the transmitter is virtually insensitive to vibration, installation close pumps, turbines or
other vibrating equipment should be avoided.
Mounting
The TP301 mounting depends on the type movement, linear or rotary. Two brackets are required for
mounting, one for the magnet and the other for the transmitter itself.
NOTE
Make sure that arrow engraved on the magnet coincides with the arrow engraved on the Position Transmitter
when the system is in mid travel. When mounting the the Position Transmitter, consider that:
1 . There is no friction between the internal magnet face and the position sensor salience all over the travel
(rotary or linear).
2. A minimum distance of 2 mm to of 4 mm distance is recommended between the magnet external face
and the Position Transmitter face.
Should the transmitter installation change, or magnet change, or should any other modification, the
transmitter will require a re-calibration.
IMPORTANT
If the self diagnostics detect a transmitter failure, for example the loss of the power, the analog signal will go
to 3.9 mA or to 21.0 mA to alert the user (High or low alarm signal is user selectable).
