INTRODUCTION
This manual gives all the installation and use instructions for XMT-SI level probes family .
GENERAL WARNINGS
• Before the installation and use of the equipment please carefully read the instructions given into this manual.
• The manufacturer is not responsible of any possible operation not mentioned into this manual.
• Any failure or faulty operation would occur to the equipment, please refer to the authorized personnel for
maintenance or directly to the manufacturer.
• The manufacturer refuses all responsibility for any eventual injury and/or damage to things caused to the non-
observance of the safety regulations.
• The assigned personnel is required to know all the safety regulations relative to the hereby described
equipment.
• Any doubt may occur about the functioning of the equipment please refer to the authorized personnel for
maintenance or directly to the manufacturer.
• Tampering releases the manufacturer from any responsibility in front of the competent authority.
• This product is used in fuel tanks and in hazardous areas for risk of explosion and fire.
Subterranean leakages of the fuel tanks may cause serious damages to environment and injury.
• If mixed with air, the flammable vapors may cause explosion. Hazardous areas may be originated
therefore by the presence of gas or vapors.
• Explosions or fire may cause damages, even lethal.
• The magnetostrictive probe can be installed in hazardous areas.

GENERAL INFORMATION
The magnetostrictive level transmitters are based on the principle named Wiedemann effect and enable continuous
and highly accurate reading of liquid’s level.
The XMT-SI level transmitter consists of a microprocessor based electronic circuit placed inside one aluminium
case head and a stainless steel shaft containing a wave guide placed inside the tank.
An high frequence electric impulse is transmitted through the electronic device. In the matching point with the
magnetic field generated by the permanent magnet placed inside the float, a mechanic impulse is generated thanks
to the magnetostrictive torsional strain. The mechanic impulse spreads through the wave guide to the speed of
sound up to the sensor placed in the measuring head. The timing between the transmission of the going impulse
and the return impulse exactly defines the position of the floats.
XMT-SI family are high precision measure instrumentation which are suitable to measure product level, water level
and temperature in various type of underground and above ground tank, also placed in hazardous areas.
The XMT-SI family is intrinsically safe certified for 0 Zone and through an intrinsically safety barrier can be
connected to console or PC positioned in a safety zone for having a complete control of the tank.
The following models are available:
XMT-SI-485 transmits data on the 485 bus. It can be configured for polling mode or push mode functioning based
on the needing. It is externally powered by the communication bus.
XMT-SI-RF transmits data using a radiofrequency transmission with variable frequency depending on the level
changes inside the tank. It is powered by a lithium battery positioned inside the probe and certified also for
intrinsically safety. In order to grant the intrinsically safety of the transmitter, the battery must be replaced only by
another one supplied by Start Italiana.
XMT-SI-TTL transmits data using a TTL interface for OEM applications. The associated instrument must be
certified in case it is necessary to install the product in a certified zone.
XMT-SI-485-LOG transmits data on a 485 bus. It is configured for functioning in polling mode. Normally it is
powered externally using a communication bus. If the external power is disconnected, automatically a battery
placed inside allows to keep the probe working and stores the level changes in a non-volatile memory for
subsequent download of the data possible on recovery of the main supply.
