UbiBot PT100-3M-R-USB Industrial Grade Temperature Probe for WS1 Pro 3 Metres
Features
Ubibot Industrial Grade Temperature Probe for WS1 Pro 3 Metres - Micro USB Connector
This product adopts modbus-rtu protocol, and the computer can monitor the temperature through the communication mode of RS485 interface. Cooperate with WS1 Pro series product to monitor the data on computer platform or mobile APP, and generate temperature data report through the platform.
The PT100 probe is made of specially treated platinum wire wrapped around the inner surface of the probe. Compared with the general axial thermal resistance, it can reflect the actual temperature of the measured object quickly and accurately. The butt cock line is made of high temperature zone shielded fiberglass material, with a temperature range of up to 200 degrees Celsius. PT100 adopts the 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 probe can be continuously measured in water.
- RS485 Interface
- High precision, wide range, good consistency
- Super stability and anti-interference
- Wide voltage input,DC5-12V
- Standard MODBUS RTU protocol
Cooperate with WS1 Pro to achieve remote monitoring, report generation and other functions

Widely used in chemical plants, power plants, oil refineries, cold storage, sewage treatment plants, steel plants, food plants and other industrial temperature measurement sites.

Note
1. Do not directly place the transmitter in a high temperature environment.
2. It is prohibited to place the transmitter in the environment of steam, water mist, water curtain or condensation for a long time.
3. The temperature tolerance of the probe butt cock line is 200?. Exceeding this temperature will lead to the failure of normal temperature measurement and even permanent damage.
4. Once the waterproof box of transmitter is opened, it will not be returned or replaced.
