2.2 Scope of delivery
INFORMATION!
Do a check of the packing list to make sure that you have all the elements given in the order.
Figure 2-1: Scope of delivery
1 Signal converter and probe.
2 Probe segments. For the assembly procedure of the single rod probe, refer to the instructions that are supplied with
the device. If a single rod or coaxial probe is attached and you ordered the "segmented probe" option, only part of the
probe is attached to the device. For the assembly procedure of the segmented single rod probe, refer to the instruc-
tions that are supplied with the device. For the assembly procedure of the segmented coaxial probe, refer to the in-
structions that are supplied with the device.

2.3 Visual check
If the device is supplied with an FKM/FPM gasket, there is no symbol on the side of the process
connection.
INFORMATION!
Inspect the packaging carefully for damages or signs of rough handling. Report damage to the
carrier and to the local office of the manufacturer.
Figure 2-2: Visual check
1 Device nameplate (for more data, refer to the handbook)
2 Process connection data (size and pressure rating, material reference and heat number)
3 Gasket material data –refer to the illustration that follows
Figure 2-3: Symbols for the supplied gasket material (on the side of the process connection)
1 EPDM
2 Kalrez®6375
INFORMATION!
Look at the device nameplate to ensure that the device is delivered according to your order.
Check for the correct supply voltage printed on the nameplate.

2.4 Storage
•Store the device in a dry and dust-free location.
•Store the device in its original packing.
2.5 Transport
WARNING!
Do not keep the device in a vertical position. This will damage the probe and the device will not
measure correctly.
Figure 2-4: Storage conditions
1 Do not bend rod and coaxial probes –support here
2 Storage temperature range: -50…+85°C/-60…+185°F (min. -40°C/-40°F for devices with the integrated LCD display
option)
Figure 2-5: How to hold the device
1 Wind cable probes greater than 400 mm / 16¨in diameter.
2 Do not hold the probe when you lift the device.
3 Do not wind the electrical cable less than 330 mm / 13¨in diameter.
WARNING!
If you do not lift the device carefully, you can cause damage to the probe.

2.6 Pre-installation requirements
•Make sure that there is sufficient space on all sides.
•Protect the signal converter from direct sunlight. If necessary, install the weather protection
accessory.
•Do not subject the signal converter to heavy vibrations.
2.7 How to prepare the tank before you install the device
2.7.1 Pressure and temperature ranges
INFORMATION!
Obey the precautions that follow to make sure that the device is correctly installed.
CAUTION!
To avoid measuring errors and device malfunction, obey these precautions.
Figure 2-6: Pressure and temperature ranges
1 Temperature at the process connection
The temperature at the process connection must stay in the temperature range of the gasket material unless the de-
vice is a High-Temperature version. Refer to the table "Permitted temperature ranges for gaskets" that follows and
to "Technical data" in the handbook.
Devices with Hazardous Location approvals: see supplementary instructions
2 Ambient temperature for operation of the display
-20...+60°C / -4...+140°F
If the ambient temperature is not between these limits, the display screen switches off automatically
3 Ambient temperature
Non-Ex devices: min. (Compact) -36°C/-33°F, min. (Remote) -37°C/-34.6°F max. +80°C / +176°F
Devices with Hazardous Location approvals: see supplementary instructions
4 Process pressure
-1...40 barg / -14.5...580 psig
WARNING!
The process connection temperature range must agree with the temperature limits of the
gasket material.
