Determining Response Time to Use 

The Response Time is factory set for the fastest response time allowed for its Model. You may wish to 
select a slower response time that is more suitable for the process.  

To follow temperature variations as they occur, select a fast response time. If you prefer to "filter out" 
temperature variations, select a slower response time. In most applications, the practical approach is to 
observe the temperature display or analog current output and adjust the response time for the most 
meaningful  temperature  information  without  distracting  variations.  Observe  the  temperature 
indications  on  a  Temperature  Display,  or  chart  recorder. 

Figure  80 

illustrates  the  general  effects  of 

response times as if plotted by a chart recorder. 

 

The combination of low target temperature and fast response time will cause unstable 
temperature  indications.  When  measuring  low  target  temperatures,  adjust  the 
Response  Time  slowly  to  obtain  stable  temperature  readings.  Measurements  below 
400°F (200°C) may require a response time of one second or more. A Response Time 
setting  of  30  milliseconds  usually  provides  good  starting  point  for  higher  process 
temperatures.

Temperature display and output 

signals follow temperature 

variations as fast as minimum 

response time of instrument. 

Rapid temperature variations are 

“filtered out“ and system follows 

general trends in temperature, 

with small amounts of “ripple“. 

Sensor tracks slow variations in 

temperature ans effects of 

temperature spikes are 

eliminated.
