The core component of the Alpha Model 164 series differential pressure sensor/transmitter is a capacitive pressure sensor, which consists of a stainless steel diaphragm and a fixed electrode that together form a variable capacitor. Leveraging Alpha's proprietary patented technology, the sensor’s design and its unique detection circuit ensure excellent temperature performance and long-term stability.
The positive/negative pressure end can withstand at least 100kPa overload without damage
With temperature compensation capacitive sensitive element, to ensure the
transmitter excellent movement State/static temperature performance
Multiple pressure interfaces/output forms/installation modes are optional
True zero output of voltage
Asymmetrical bidirectional differential pressure range is optional
Full protection of misconnection
Meet the CE standard
Environmental protection design, in line with ROHS standards
Minimum pressure range of 10Pa
The Alpha Model 164 differential pressure sensor/transmitter can be used to measure differential or gauge pressure. It offers standard output options of 0–5V, 0–10V, and 4–20mA, with other outputs available for customization. At room temperature, the accuracy of Model 164 is available in three grades: ±1.0%FS, 0.4%FS, or 0.25%FS. The device supports a temperature compensation range of 4 ℃ to 77 ℃, with a temperature effect limited to less than ±0.05%FS/℃.
With its excellent performance-price ratio, the Alpha Model 164 is widely used in HVAC, environmental pollution control, clean engineering, medical instruments and equipment, oven pressurization and furnace pressure control, natural gas and pipeline network monitoring, underground ventilation, power plant wind pressure monitoring, and other related fields.
