Temperature measurement with Pt1000 / Pt100 RTD is a proven and precise approach in the industry for years.
RTDtoMQTT modernizes this approach by transmitting the measured data directly to an IIoT system (MQTT broker) or build in Modbus TCP server.
RTDtoMQTT is an industrial 4-channel device for temperature measurement by resistive temperature sensors (RTD), type Pt100 or Pt1000. The measured results are published to the MQTT broker.
24-bit measuring resolution.
RTDtoMQTT is powered by an external 24 VDC and has galvanic isolation between the micro-controller part and both the external power supply and the measurement part.
Detachable terminals for RTDtoMQTT connecting to the sensors and the external power.
Built-in WEB server (configurator) for RTDtoMQTT configuration. The WEB server is accessed via a WEB browser on an external device (PC, laptop, smartphone, etc.).
Technical features:
- Automatic recognition of the sensor type - Pt100 or Pt1000.
- Three-wire connection of the sensors, cancelation of the resistance of the connecting wires.
- Ethernet 10/100Base-T network interface.
- Protocol - TCP/IP, UDP.
- Built-in WEB server for configuration.
- Build in Modbus TCP server.
- Working as a client of a remote MQTT broker.
- External power supply 24 VDC.
- Complete galvanic isolation between the external power supply, processor, measuring and communication parts.
- LED indication for power supply and error occur - damaged sensor connection, lack of communication, etc.
- Measurement resolution - 24-bit.
- Detachable terminal blocks.
- Protection degree IP20.
- 35 mm DIN rail mounting.
RTDtoMQTT is applicable:
- for temperature monitoring in HVAC installations, facilities for transportation and storage of food, warehouse and production areas, greenhouses, furnaces, temperature chambers, boilers, tanks.
- in systems for data collection and processing (Data acquisition).
- in control and information systems for technological processes.
