SITRANS T Temperature Measurement Rail Transmitter
SITRANS TR320/420
The reliable with high accuracy
SITRANS TR320 and TR420 rail transmitters combine perfect measurement and intelligence under all conditions. Reliability is guaranteed, for example, by the TR420’s 2-fold sensor input including 4-wire sensor connection and hot backup: In the event of a sensor failure, the transmitter automatically switches to the second sensor, and the values continue to be recorded seamlessly and without loss.
The SITRANS TR300 Advantage
- High availability during measurement by hot backup function (SITRANS TR420)
- High reliability and long-term stability – sensor trim (Callendar-van-Dusen) and sensor drift detection (SITRANS TR420 only) for high accuracy and accelerated calibration time
- Avoidance of production stop because of measurement failures
- Best cost-benefit ratio for facility management
- Cost reduction through anticipatory maintenance
- Withstanding safety-critical environments – Extended temperature range up to -50°C and SIL2/3 approvals
