The core component of the Alpha Model 165 series differential pressure sensor/transmitter is a capacitive pressure sensor. It consists of a stainless steel diaphragm and a fixed electrode that together form a capacitor whose capacitance varies with pressure. Utilizing Alpha’s proprietary patented technology, the carefully designed sensor 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 165 differential pressure sensor/transmitter can be used to measure differential or gauge pressure, with standard outputs of 0–5V, 0–10V, and 4–20mA. Other output options are available upon customization. At room temperature, its accuracy is available in three grades: ±1.0%FS, 0.4%FS, or 0.25%FS. The device features a temperature compensation range from 4 ℃ to 77 ℃, with a temperature effect limited to less than ±0.05%FS/℃.
Thanks to its excellent performance‑to‑price ratio, the Alpha Model 165 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 related fields.
