Model 168 Product Introduction

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.

Model 168 Product Features

• 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

Model 168 Technical Data

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.
