Model 166

Model 166 Product Introduction

The core component of the Alpha Model 166 series differential pressure sensor/transmitter is a capacitive pressure sensor, which consists of a stainless steel diaphragm and a fixed electrode that form a capacitor with capacitance varying with pressure. Employing Alpha’s exclusive patented technology, the sensor and its dedicated detection circuit are carefully designed to deliver superior temperature performance and long-term stability.

Model 166 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 166 Technical Data

The Alpha Model 166 differential pressure sensor/transmitter can measure differential or gauge pressure and provides standard output options of 0–5V, 0–10V, and 4–20mA, with other outputs available for customization. Its accuracy at room temperature is available in three grades: ±1.0%FS, 0.4%FS, or 0.25%FS. The device supports temperature compensation from 4 ℃ to 77 ℃, with a temperature effect limited to below ±0.05%FS/℃.

With an excellent performance-to-price ratio, the Alpha Model 166 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.
