PTM3051S single crystal silicon pressure transmitter
The internal chip of the PTM3051S monocrystalline silicon pressure transmitter adopts the MEMS monocrystalline silicon pressure chip imported from Germany. The sensor signal is converted into a standard signal output by a dedicated signal processing module. After long-term aging and stability screening, the product performance is stable and reliable. It is used in harsh environment and open air conditions., at the same time can be on-site pressure display, zero, full range, etc.
Features:
1. Using German imported MEMS monocrystalline silicon pressure chip.
2. Wide range coverage
3. Two-wire system, 4～20mA HART® protocol digital communication
4, Smart LCD screen head with backlight
5. Both remote transmission and local zero and span adjustment.
6. Full range, high precision and good stability.
7. Flameproof shell structure, strong anti-frequency interference.
8. No mechanical transmission parts, strong vibration resistance.
