Milesight EM500-PT100-915M PN: T500 Platinum Temperature Sensor
Product Description
Milesight EM500-PT100-915M PN: T500 Platinum Temperature Sensor is a long-range industrial temperature monitoring system designed for high-temperature processes. This product uses the PN T500 three-wire platinum resistance temperature probe for compatible industrial machinery, ovens, boilers, chimneys, liquid and gas process equipment, and laboratory monitoring, reporting measurements over LoRaWAN®.
T500 probe only: Measurement range −50°C to +500°C, Class A accuracy, 0.1°C resolution and manufacturer-listed typical accuracy of ±0.5°C (−50°C to +170°C) and ±1.2°C (+170°C to +500°C). The straight stainless-steel 304 probe is Ø4 × 30 mm, IP30, with fiberglass cable rated −50°C to +500°C and a standard cable length of 1.5 m (customizable). The IP67 rating applies to the separate LoRaWAN transmitter; the T500 probe is IP30.
The battery-operated transceiver supports LoRaWAN® OTAA/ABP Class A and Milesight D2D, remote downlink configuration, NFC mobile-app settings and USB Type-C PC configuration. It stores up to 1,000 measurement records and provides data retransmission, retrieval, threshold and change alarms. The replaceable 19,000 mAh ER34615 Li-SOCl₂ battery has an OEM laboratory life estimate of 10 years with 10-minute reports at 25°C. The transmitter itself operates from −30°C to +70°C, not at the T500 probe's maximum sensing temperature.
Regional frequency: TwoElectrons SKU 2ESE2188 is listed as EM500-PT100-915M T500. IN865 is one of the manufacturer’s regional LoRaWAN options, but the frequency compatibility of the supplied 915M unit must be confirmed for Indian installation. Specifications on this page are for T500 only, not other PT100 probe models.
