The core component of the Alpha Model 168 series differential pressure sensor/transmitter is a capacitive pressure sensor, which comprises a stainless steel diaphragm and a fixed electrode that together form a capacitor with capacitance varying in response to pressure. By leveraging Alpha's proprietary patented technology, the sensor and its dedicated detection circuit are meticulously 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 168 differential pressure sensor/transmitter can be used to measure both differential and 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 device is available in three accuracy grades: ±1.0%FS, 0.4%FS, or 0.25%FS. It supports temperature compensation from 4 ℃ to 77 ℃, with a temperature effect maintained below ±0.05%FS/℃.
With its outstanding
performance-price ratio, the Alpha Model 168 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 applications.
