The core component of the Alpha Model 162 series differential pressure
sensor/transmitter is a capacitive pressure sensor, which consists of a
stainless steel diaphragm and a fixed electrode to form a capacitor
whose capacitance varies with pressure. Leveraging Alpha’s proprietary
patented technology, the sensor and its unique detection circuit are
carefully designed to 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 162 differential pressure sensor/transmitter can measure differential or gauge pressure, offering standard output options of 0‑5V, 0‑10V, and 4‑20mA, with other outputs available for customization. At room temperature, its accuracy can reach ±1.0%FS, 0.4%FS, or 0.25%FS. The temperature compensation range spans from 4 ℃ to 77 ℃, with a temperature effect limited to below ±0.05%FS/℃.
With its outstanding performance‑price ratio, the Alpha Model 162 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.
