Production process of pressure transmitter
- Component screening: A good pressure transmitter starts with components. From screening test to qualified employment, we check at every level to provide you with high-quality pressure transmitters.
- 6 times accuracy standard: Germany General Electric automatic calibration system is adopted. Each product has been accurately calibrated 6 times from production to delivery. Three-point detection of zero point, mid-point and full scale covers the full range, and the measurement accuracy is much higher than that of two-point calibration.
- High-temperature aging detection: high-temperature detection, aging detection, core body detection, component detection, finished product detection, and out-of-warehouse detection. Each pressure transmitter has undergone a 48-hour high temperature test. Nearly ten testing procedures ensure that each pressure transmitter is durable.
- Laser marking: Each pressure transmitter has a corresponding “identity number”. From production to testing, digital management.
