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).
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.
- 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.
