Installation
As part of the installation please check that:
•
the serial numbers on the transducer, amplifier and lid of amplifier box complies. The serial num-
bers are found on the S/N on the amplifier box at the bottom line and on the transducer S/N on
the range label.
•
the transducer is fitted in the correct tank.
•
the transducer is correctly connected to the amplifier.
•
all cable glands are properly secured to the amplifier box. Use torque of 6 Nm.
•
the amplifier box is mounted in such a way that the breather tube cannot be flooded.
•
the cable is fastened with cable clips with a distance of max. 50 cm.
•
the cable isolation is not damaged (cracks, weld spatter, burns etc.).
•
shut-off valves can be either ball valves or other valves not generating over pressure exceeding 4
x the transducer range between valve seat and transducer when the valve is closed.
Note!
The white and brown wires in the transducer cable are only used when a Pt100 sensor is
built into the transducer.
As for flange mounted applications it is recommended that a ball valve is fitted in the front of the
transducer to facilitate testing and calibration of the transmitter.
The power cable / 4 - 20 mA signal cable shall be a cable with solid insulation; the minimum wire insu-
lation must be 0.25 mm for each wire. Using a shielded cable for the 4-20 mA signal, the shield shall
be connected at the earth terminal of the I/O system (e.g. simple gauge or tank monitoring system)
and not in the amplifier box. Using a shielded cable ensures maximum protection against electrical
noise.
If the amplifier box is installed in an area with over pressure or negative pressure in relation to the
atmospheric pressure in the tank, the breather tube must be directed to an area with atmospheric
pressure equal to the pressure inside the tank. This applies to gauge transmitters only. For absolute
transmitters this has no affect, due to the reference to absolute vacuum and not atmospheric pres-
sure. This is also the reason why no breather tube is necessary.
