Intermittent Sensor Detect
(Advanced Function)

(1)

NOTE

The Intermittent Sensor Detect feature is not available in previous 
versions of the Model 3144 and 3244MV transmitters (see Appendix A: 
Transmitter Improvements).

The Intermittent Sensor Detect feature is designed to guard against 
process temperature spikes causes by intermittent sensor conditions 
(an intermittent sensor condition is an open sensor condition that lasts 
less than 0.7 seconds). By default, the transmitter is shipped with the 
Intermittent Sensor Detect feature switched ON and the threshold 
value set at 2% of output range. In most applications, this is the 
preferred setting. The Intermittent Sensor Detect feature can be 
switched ON or OFF, and the threshold value can be changed to any 
value between 0 and 100% of output range with a HART communicator.

Transmitter Behavior with Intermittent Sensor Detect ON

When the Intermittent Sensor Detect feature is switched ON, the 
transmitter can eliminate the output pulsing caused by intermittent 
open sensor conditions. Process temperature changes within the 
threshold value will be tracked normally by the transmitter’s output. A 
temperature change greater than the threshold value will activate the 
intermittent sensor algorithm. True open sensor conditions will cause 
the transmitter to go into alarm. A detailed description of the 
intermittent sensor algorithm can be found under “Intermittent Sensor 
Algorithm” on page 5-15.

The threshold value should be set at a level that allows the normal 
range of process temperature fluctuations: too high and the algorithm 
will not be able to filter out intermittent conditions; too low and the 
algorithm will be activated unnecessarily. The default threshold value 
is 2% of output range.

Transmitter Behavior with Intermittent Sensor Detect OFF

When the Intermittent Sensor Detect feature is OFF, the transmitter 
tracks all process temperature changes, even if these are the 
consequence of an intermittent sensor. (The transmitter in effect 
behaves as though the threshold value had been set at 100%.) The 
output delay due to the intermittent sensor algorithm will be 
eliminated.

The Intermittent Sensor Detect command is not available in previous versions of the Model 3144 and 3244MV transmitters.
