Products Description
Intelligent transmitters are generally hybrid intelligent transmitters with both digital and analog signals. Communication with DCS mainly involves transmitting 4-20mA analog signals, and then overlaying digital signals on top of them for remote setting of zero and range, as well as calibration, configuration, and diagnosis of the transmitter. It is only designed for compatibility with existing DCS and is a true transition product to fully digital intelligent transmitters (such as fieldbus type intelligent transmitters).
Technical Parameters
| Working temperature | -20 ℃ to 80 ℃; | Thermal sensitivity drift | When the ambient temperature deviates from the reference working condition temperature, the full range drift of the transmitter should not exceed 0.03% FS/℃. |
| Basic error | Insulation resistance | Under reference working conditions, the insulation resistance between the terminals of the transmitter and the ground shall not be less than 20M Ω/250V. | |
| The accuracy level of the transmitter is divided into | 0.1 level, with a basic error of ± 0.1; 0.3 level, with a basic error of ± 0.3; Level 0.5, with a basic error of ± 0.5 (expressed as a percentage of the range). | Explosion proof performance | The explosion-proof performance of the instrument meets the requirements of Exia II CT6 Gb. |
| Thermal zero drift | When the ambient temperature deviates from the reference working condition temperature, the zero drift of the transmitter should not exceed 0.03% FS/℃. |
