Industrial PT100 temperature sensor

Milesight EM500-PT100-868M is an industrial LoRaWAN temperature sensor designed for contact monitoring of very low temperatures. The variant T050 uses a 3-wire Class B PT100 probe and enables measurement over a wide range from −200°C to +50°C.

The 304 stainless steel probe and Teflon cable rated for temperatures from −200°C to +290°C make the device suitable for applications including refrigeration, low-temperature installations, laboratories, and industrial processes. The IP67 LoRaWAN module features a 19 000 mAh battery, storage for 1000 records, and alarm and data retransmission functions.

EM500-PT100 T050 — Temperature Monitoring Down to −200°C

Milesight EM500-PT100 in the T050 variant is a wireless temperature sensor designed for contact measurements in low-temperature installations and processes.

The Class B PT100 probe enables measurement from −200°C to +50°C. A 3-wire connection, 304 stainless steel probe, and Teflon cable make the device suitable for refrigeration, laboratories, process installations, and other applications requiring very low temperature monitoring.

Temperature Monitoring from −200°C

Range −200…+50°C

The T050 variant is designed for applications where standard industrial temperature sensors do not provide a sufficiently low operating range.

Class B PT100

The platinum PT100 resistance temperature sensor provides stable temperature measurement even at very low ranges.

Wireless LoRaWAN

Measurements can be automatically transmitted to a central system without the need for wired communication infrastructure.

Temperature Measurement Down to −200°C

The T050 differs from other EM500-PT100 variants primarily by its very low lower measurement limit of −200°C.

This makes the device suitable where standard probes designed for typical industrial or refrigeration monitoring do not offer a sufficient measurement range.

Design Prepared for Low Temperatures

304 Stainless Steel

The straight probe is made of 304 stainless steel and has a diameter of 4 mm and a measurement section length of 30 mm.

Teflon Cable

The probe cable is designed for operation from −200°C to +290°C, matching the low-temperature application of the T050.

3-Wire Connection

The 3-wire configuration reduces the impact of cable resistance on the measurement result and supports stability of the entire measurement circuit.

Automatic 24/7 Temperature Control

The EM500-PT100 replaces periodic manual temperature checks with continuous measurement and automatic data reporting via LoRaWAN.

Measurement history can be used to analyse storage and process conditions, while alarms enable rapid response when defined temperature values are exceeded.

Local Storage and Alarming

1000 Records

The EM500-PT100 can locally store up to 1000 historical measurement records.

Data Retransmission

Data stored during temporary communication loss can be retransmitted after the connection to the LoRaWAN network is restored.

Temperature Alarms

Threshold alarms and rapid temperature-change alarms enable earlier detection of unwanted conditions in the monitored process.

EM500-PT100 in a Temperature Monitoring System

Measurements from the PT100 probe can be automatically transmitted via LoRaWAN to a gateway and then to a central platform. This makes it possible to monitor multiple points, archive temperature history, and generate alarms.
