Range = x (1.2-1.5) times the maximum temperature of the system;
The actual measuring pressure range of the product should be 15% - 80% of the measuring range;

2. Product output / accuracy level / power supply mode:
Current type: 4-20mA (two-wire system), 0-20mA (three wire system);
Voltage type: 0-5vdc, 0-10vdc, 0.5-4.5vdc (three wire system);
Digital communication type: rs485-rtu, TTL, RS232, low power consumption RS485 (four wire system);

Supply voltage:
24VDC (12-30vdc) / general type output signal power supply;
5VDC / output 0.5-4.5vdc;
3.7vdc (or battery powered) / low power output power supply;

3. Users need to understand the characteristics of the measuring medium of the product:
Medium specification, medium temperature, medium purity (whether it contains impurities or particles, etc.);

4. Users should understand the installation environment and installation method of the product:
Indoor or outdoor installation;
Ambient temperature;
Required sealing grade;
Vibration range of equipment;

Precautions for use of Pt100 temperature transmitter

For installation and use, please check whether the relevant parameters of the product label and certificate are consistent with the operating conditions;
When the thermal resistance / thermocouple is installed, its insertion depth shall not be less than 8 ~ 10 times of the outer diameter of the thermal resistance protection tube;
Increase the heating part of thermal resistance / thermocouple as much as possible;
The thermal resistance / thermocouple shall be installed vertically as far as possible to prevent bending and deformation at high temperature.
In order to reduce the error during the use of thermal resistance / thermocouple, the surface of protective sleeve shall be close to the temperature of measured medium as much as possible;
When installing the product, the stressed part is "process connection hexagonal wrench position", and the wrench specification corresponds to the hexagonal wrench position;
It is strictly prohibited that the medium temperature, pressure range and excitation voltage of the measured system exceed the rated service range of the transmitter;
Pay attention to protect the sensor / transmitter cable or compensation wire;
Try to avoid direct access to user devices or electrical appliances causing interference;
