Process temperature range

• –60 to +230 °C (–76 to +446 °F)
• –60 to +280 °C (–76 to +536 °F)/to 300 °C (572 °F) for max. 50 h on cumulative basis
• –50 to +230 °C (–58 to +446 °F) with PFA coating (conductive)
The device can be ordered for use in very aggressive media with a highly corrosion-
resistant PFA coating. At medium temperatures up to ≥ 150 °C (302 °F), pay attention to
the chemical durability and the increasing risk of damage to the coating from diffusion.

Thermal shock

Without restrictions within the process temperature range.
With PFA coating (conductive): ≤ 120 K/s

Process pressure range

WARNING
L
The maximum pressure for the device depends on the lowest-rated element, with
regard to pressure, of the selected component. This means that it is necessary to pay
attention to the process connection as well as the sensor.
‣
For pressure specifications, see the "Mechanical construction" section.
‣
Only operate the device within the specified limits!
‣
The Pressure Equipment Directive (2014/68/EU) uses the abbreviation "PS". The
abbreviation "PS" corresponds to the MWP (maximum working pressure) of the device.
