2. Data Frame Format:
The Modbus-RTU communication protocol is used in the following
format:
- Initial Structure: 4 bytes in time.
- Address code: 1 byte, default 0xC2.
- Function code: 1 byte, support function code 0x03 (read only)
and 0x06 (read/write). - Data area: N bytes, 16-bit data, high byte comes first.
- Error check: 16-bit CRC code.
- End Structure: 4 bytes of time.
Product Application:
- Do not directly place the sensor in a high-temperature
environment or the environment of steam, water mist, water curtain,
or condensation for a long time. - The temperature tolerance of the sensor tail line is 200°C.
Exceeding this temperature will lead to the failure of normal
temperature measurement and even permanent damage.
Frequently Asked Questions (FAQ):
Q: What is the recommended working temperature range for the
sensor?
A: The sensor has a working temperature range of -30°C to
200°C.
Q: What communication protocol does the device support?

Introduction
The PT100 sensor is made of specially treated platinum wire wrapped around the inner surface of the sensor. Compared with the general axial thermal resistance, it can reflect the actual temperature of the measured object quickly and accurately. The sensor chip imported from Germany with high stability, and adopts a more stable three-wire connection mode to ensure the accuracy of temperature measurement and anti-interference ability of the system.The probe shell is made of 304 stainless steel, which has good resistance to acid and alkali corrosion. The shell is completely wrapped and can reach IP68 waterproof grade, which means the sensor can be continuously measured in water.
Use Case Scenarios Widely used in chemical plants, power plants, oil refineries, cold storage, sewage treatment plants, steel plants, food plants and other industrial temperature measurement sites.
Features High precision, wide range, good consistency. Super stability and anti-interference. Standard MODBUS RTU protocol.
