Example for calculating measured error for ambient temperature drift:
Input temperature drift Δϑ = 10 K (18 °F), Pt100, measuring range 0 to 100 °C (32 to 212 °F)
Maximum process temperature: 100 °C (212 °F)
Measured resistance value: 138.5 Ω (IEC 60751) at maximum process temperature
Typical temperature drift in Ω: (0.001% of 138.5 Ω) * 10 = 0.01385 Ω
Conversion to Kelvin: 0.01385 Ω / 0.385 Ω/K = 0.04 K (0.054 °F)

Environment conditions

• Without display: -40 to +185 °F (-40 to +85 °C)
• With display: -40 to +176 °F (-40 to +80 °C)
For use in hazardous area, see Ex certification or control drawing
At temperatures < -4 °F (-20 °C) the display may react slowly. Readability of the display
cannot be guaranteed at temperatures < -30 °C (-22 °F).

Care should be taken when using L-form brackets (see wall/tube 2" brackets in Section
'Accessories') since this can cause resonance. Caution: vibrations at the transmitter must
not exceed the specified values.
CE Electromagnetic Compatibility Compliance
EMC meets all relevant requirements listed under EN 61326 Series and NAMUR NE21. Details as
per declaration of conformity.
This recommendation is a uniform and practical way of determining whether the devices used in
laboratories and process control are immune to interference with an objective to increase its
functional safety.
