| Ordering tips of Electronic Pressure Switch |
1. When choosing products, please make sure that adapted to product contact parts of the measured medium.
2. When ordering, please indicate the power supply, precision level, number of control points, whether with RS485 interface.
3. The measuring range of flat diaphragm pressure controller is 0~35KPa... 20MPa.
4. For users who choose differential pressure measurement, attention should be paid to the relationship between the differential pressure range and the allowable overpressure and maximum pressure of the high and low pressure chamber, and ensure that it meets the requirements of field application. In order to ensure the safe and reliable operation of the product, it is recommended to install a three-valve manifold between the measuring point and the transmitter.
5. In order to ensure reliable operation of the product, it is recommended to install lightning protection device on site and ensure reliable grounding of the product and power supply. In case of strong vibration, instantaneous impact force, strong electromagnetic interference, RF interference and other special requirements, please inform our company and indicate in the order.
