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.
Where Can the EM500-PT100 T050 Be Used?
Key Measurement Parameters
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.
Communication, Power Supply and Design
* The manufacturer declares up to 10 years of operation with a 10-minute reporting interval and a temperature of 25°C. Actual battery life depends on configuration, communication conditions, and operating environment.
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.
