Display and user interface Display and user interface Display and user interface Display and user interface
Display Only in connection head "BUZ-HW": 4...20 mA, non-illuminated, LCD,
loop display.
Operating Only in connection head "BUZ-HW": interior keys.
Display functions Temperature, either as output signal (HART ® penetrable) in mA or
scaled to °C/°F.
Measuring accuracy
Reference conditions Ambient temperature: +23°C / +73.4°F (fluctuations due to air
pressure and density have no impact on measuring accuracy).
Maximum measuring error More detailed information in the subsection "Measurement Error",
this section. The maximum measurement error also depends on the
type of sensor:
• Measuring insert with Pt100 RTD: measurement error in
accordance with tolerance classes A, B and 1/3 B as per
DIN EN 60751.
• Thermocouple: measurement error in accordance with tolerance
class 1 as per DIN EN 60584.
Operating conditions
Load limits The load limits depend on several factors (e.g. dimensions, design
and material of thermowell). Other information can be found in the
"Installation" section or in separate subsections of this section.
Thermometer without thermowell: 0.8...1.2 bara / 11.6...17.4 psia.
Temperature Temperature Temperature Temperature
Process temperature Maximum -200...+600°C / -328...+1112°F, depending on measuring
insert, design and material.
Ambient temperature Maximum -40...+100°C / -40...+212°F, depending on the connection
head and measuring insert.
Storage temperature -40...+70°C / -40...+158°F at 40...60% relative humidity.
Other conditions Other conditions Other conditions Other conditions
Protection categories Dependent on the connection head: IP 54 (BKK), IP 65 (BA, BUZ-
T/S/H/HW, BVA), IP 67 (BGK), IP 68 (AXD).
