Operating hours counter in temperature classes

The SITRANS TR200/TR300 has different operating hours counters. The operating hours
counters are for monitoring the connected process flows.
1. Operating hours counter for transmitter electronics
● Monitors the number of operating hours that the transmitter has been in continuous
● Records the process of operating hours of the transmitter in 9 ranges of ambient
● Begins with the first commissioning at the plant.
● The user cannot reset or adjust the operating hours counter or temperature ranges.
● The operating hours counter is only updated when it is in measuring mode. The operating
2. Operating hours counter for process variable
● Monitors the process of the sensor connected to the transmitter in different process
● Records the process of operating hours of the process variable in 9 ranges. Subdivision
● The operating hours counter is reset automatically if one of its following parameters is
The parameter assignment software SIPROM T for SITRANS TR200 or SIMATIC PDM or
HART communicator on SITRANS TR300 can read out the operating hours counters. The
operating hours counters are automatically stored to the non-volatile memory once an hour.
If the power supply to the device is interrupted, the operating hours counters are available
upon restarting the device.
