1. SAFETY
1.1 Installation precaution
a)
Installation shall only be performed by qualified personnel and in accordance with local governing regulations.
b)
Make sure that the working temperature is between -35° and +75°C
c)
Install the transmitter in a its physical characteristics and housing/sensor construction materials compatible environment.
d)
The transmitter must be used safety warnings observance.
e)
Improper transmitter use would cause serious damage to people, to the product and connected equipment.
The non intrusive system application is now preferred in the level measurements field. For this reason the
SGM-LEKTRA
developed the
PTU50
,
PTU51
and
PTU56
unity to best meet the “
GENERAL-PURPOSE
” application requests. The
PTU50
,
PTU51
and
PTU56
units are compact sensors and have a via connector quick connection. The
IP68
protection
makes them suitable for external applications with direct exposure to the weather, including areas with diving hazard (up
to 1m).
PTU50
,
PTU51
and
PTU56
are ultrasonic level transmitter, temperature-compensated and suitable for connection
with
MODBUS RTU
.
