Models 3144 & 3244MV Smart Temperature Transmitters
 The Models 3144 and 3244MV
temperature transmitters provide superior accuracy, stability, and
reliability, making them the industry-leading temperature transmitters used
in control and safety applications. The Model 3144 is a single-sensor input
transmitter. The Model 3244MV has a dual-sensor input capability that allows
the transmitter to accept simultaneous input from two independent sensors.
You can use this transmitter for measuring differential temperatures,
averaging temperature or redundant temperature measurement.
- Industry leading 5 year stability, which reduces maintenance costs
- Hot Backup® feature in the
Model 3244MV automatically switches to the backup sensor if the primary sensor
fails
- Transmitter-Sensor matching eliminates
sensor interchangeability error, which improves accuracy by 75%
- Dual-compartment housing that provides the highest reliability in
harsh environments
- Highest accuracy differential temperature measurement on the Model 3244MV
- Sensor Drift Alert in the Model 3244MV enables continuous monitoring of the
differential temperature for two sensors.
- Integral LCD meter with large, easy to read display
- RTD, thermocouple, ohm and millivolt inputs accepted
- Hard-wired failure jumper for reliable failure modes
