Process

• –60 to +230 °C (–76 to +446 °F)
• –60 to +280 °C (–76 to +536 °F)
• –50 to +230 °C (–58 to +446 °F) with PFA coating (conductive)
• 300 °C (572 °F) for a maximum of 50 h (cumulative)
Pay attention to the pressure and temperature dependence, see the "Sensor process pressure range"
section.
Without restrictions within the process temperature range.
With PFA coating (conductive): ≤ 120 K/s
WARNING
L
The maximum pressure for the measuring device is dependent on the lowest-rated element,
with regard to pressure, of the selected components. 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.
‣
The measuring device must be operated only 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 measuring device.
