✔ High Accuracy: ±0.15% of span for thermocouples, ±0.08% for Pt100.
✔ Cold Junction Compensation: Improves thermocouple accuracy.
✔ Remote Configuration: Configurable via SigNow software, TxConfig II software, or SigNow app.
✔ Loop-Powered 4-20 mA Output: Provides linearized output proportional to input.
✔ Fast Response Time: Typical response time of 6 seconds.
The resilience of NOVUS devices and the established quality of HART® certification are combined in the temperature transmitter TxIsoBlock-HRT. The transmitter supports voltage spikes up to 1.5 kVrms and offers electrical isolation between input and output. It is compatible with devices that have earned the HART® certification. The main difference is that it has two 4-20 mA current loop wires for total configuration, which means more functionality for monitoring and device setting.
The TxIsoBlock-HRT Temperature Transmitter from NOVUS combines robust industrial design with advanced HART® protocol communication, making it an ideal solution for precise temperature measurement and smart device integration.
