The resilience of NOVUS devices and the established quality of HART® certification are combined in the temperature transmitter TxIsoRail-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.
NOVUS’s temperature transmitter TxIsoRail-HRT uses a globally recognized protocol with over 40 million field instruments that accept HART® technology.
TxIsoRail-HRT Temperature Transmitter
The TxIsoRail-HRT temperature transmitter by NOVUS combines the proven reliability of NOVUS hardware with the advanced communication capabilities of the HART® protocol. Designed for industrial applications, it supports universal sensor inputs including thermocouples (J, K, T, N, R, S, B, E), RTDs (Pt100, Pt1000), NTC thermistors, and low voltage signals (0-50 mV).
Key features include:
-
HART® Certification: Supports HART V7 and is backward compatible with HART V5, enabling two-way digital communication over the standard 4-20 mA current loop for remote configuration, diagnostics, and monitoring.
-
Electrical Isolation: Provides 1.5 kVrms isolation between input and output, protecting the system against voltage surges and ensuring signal integrity.
-
High Accuracy: Typical accuracy ranges from 0.07% to 0.2% of span depending on sensor type, with low thermal drift (<0.05% per 25 °C).
-
Robust Design: Operates reliably in harsh environments with a temperature range of -40 to 85 °C and up to 90% relative humidity.
-
DIN Rail Mounting: Compact design for easy installation on standard 35 mm DIN rails.
-
Power Supply: Loop powered (8.5 to 36 Vdc), simplifying wiring and reducing installation costs.
-
Comprehensive Compliance: CE, NAMUR NE43, RoHS, REACH, and electromagnetic compatibility standards ensure suitability for industrial environments.
-
Configuration: Can be configured via TxConfig-HRT adapter or any HART-certified handheld device using TxConfigII software.
