PT100 RTD Temperature Sensor Module with RS485 MODBUS RTU -20°C to 400°C Industrial Temperature Transmitter

Tired of unreliable temperature readings in your industrial setup? The PT100 RTD Temperature Sensor Module with RS485 MODBUS RTU gives you precise, stable measurements from -20°C to 400°C — ready to plug straight into your PLC, SCADA, or control system.

This industrial-grade temperature transmitter converts PT100 RTD sensor signals into clean RS485 MODBUS RTU digital output, eliminating signal noise and long-distance interference that plague analog systems. It supports both 2-wire and 3-wire PT100 probes, reads actual temperature and PT100 resistance values simultaneously, and communicates at a default 9600 baud rate using standard MODBUS function codes (03 read / 06 write). The corrosion-resistant platinum sensing element ensures long-term accuracy even in harsh, high-humidity, or chemically aggressive environments.

What truly sets this module apart is its multi-drop cascading capability — assign unique RS485 addresses and chain up to 247 modules on a single bus. Whether you're monitoring furnace zones, HVAC ducts, laboratory ovens, or industrial pipelines, one cable run handles your entire network. At ₹659, this is a fraction of what branded industrial transmitters cost, making it the smart choice for engineers, automation professionals, and makers scaling up temperature monitoring without scaling up their budget.
