Pt1000 temperature transmitter 3S-MT-PT1000-U

0-10 Vvoltage outputIP67

Overview
Module temperature sensor measures the back of the solar panels temperature in degrees Celsius (°C) by using a PT1000 probe. The probe is placed between two backsheet layers with an EVA sheet to measure the back of module temperature. A transducer converts the PT1000 signal to an analog 0-10 V output. This model is compatible with dataloggers, gateways, and PLCs that have a 0-10 V input port.

Working principle
Professional, intelligent measurement sensor designed to track the rear surface temperature of photovoltaic modules. A high-precision PT1000 sensor measures the PV module temperature and an electronic card housed in a UV-resistant protective enclosure converts it to an analog 0–10 V output.

Installation
IEC 61724-1:2021 states the module temperature sensor shall be placed at the center of a cell near the midpoint of the module, avoiding cell boundaries. The sensor should be placed closest to the center of the cell, on a dry and contaminant-free area. Note that dew or residues in winter may make attachment difficult.

Advantages

• Estimating PR: provides precise module temperature data required for accurate Performance Ratio calculations.
• Protection Against Overheating: real-time temperature data allows control systems to mitigate overheating and prevent long-term damage.
• Weather Adaptability: enables dynamic system responses to changing weather conditions to maximize energy yield.

Why Seven Sensor Solutions
SEVEN products use premium components and the sensor structure closely resembles the backside structure of a PV module to ensure comparable heat transfer behavior. The 3S-MT module temperature sensor is designed to meet Annex B of IEC 61724-1:2021 and IEC 60751:2022, delivering resolution ≤ 0.1 °C and uncertainty ±1 °C aligning with the standards.
