Testermeter-FST100-1001 Low Power Pressure Transmitter
【Product Description】
| FST100-1001 low-power pressure transmitter is based on MEMS technology and adopts advanced glass micro-melting technology, which avoids the influence of temperature, humidity, mechanical fatigue and media on the product, and strengthens the long-term stability of the sensor in the industrial environment. The pressure chamber adopts the overall processing technology of A17-4PH stainless steel, no welding seam, no "O" ring, and no hidden danger of leakage. It is a low-power digital pressure sensor, which adopts imported high-quality pressure-sensing core body, combined with microprocessor technology and sensor digital conversion technology design, adopts laser welding process as a whole, safe and non-leakage, advanced temperature digital compensation, wide working temperature range . Ultra-low power consumption design, easy to use, good stability. It is suitable for the Internet of Things such as fire water, water affairs, heating, and other occasions that require low-power battery power supply. |
