Main Features
| Features | Description |
| Flexible sensor configuration | HART-Tool configuration software can flexibly and conveniently configure the measurement range of sensors and the range of transmitter boards. |
| Flexible temperature compensation | Supports to set 2 to 11 temperature points and 1 to 15 pressure points at each temperature. The temperature compensation methods are highly flexible and can meet the different needs of users. For example, only compensating the zero point; compensating both the zero point and the range simultaneously; or compensating the zero point, the range and the linearity. |
| Strong on-site anti-interference capability | •Protected by conformal coating, which can effectively prevent the damage to the electronic components caused by the external environment.
•Equipped with anti-interference devices such as high-power TVS (Transient Voltage Suppressor) and magnetic beads internally, effectively suppressing various interferences on site. •The EEPROM has an enhanced anti-interference design and complete data backup and recovery functions, thoroughly realizing maintenance-free operation on site. |
| Intelligent Self-inspection | The software has the function of intelligent self-inspection, further ensuring high reliability on-site. |
| Useful Tools | •HART-Tool configuration software: For the configuration and debugging of transmitter boards. For small-batch production of transmitter boards, this software can also be used.
•HART intelligent transmitter board batch-production software: With dedicated tooling, it can simultaneously complete linearization, temperature compensation, configuration, etc. of multiple transmitter boards. |
