The core component of the Model 161 series differential pressure
sensor/transmitter is a capacitive pressure sensor, which consists of a
stainless steel diaphragm with a fixed electrode forming a capacitor
whose value varies with pressure. Using the company's special patented
technology carefully designed sensor sensors and unique detection
circuit to ensure good temperature performance and long-term stability
of the product.

The Model 161 differential pressure
sensor/transmitter can be used to measure differential or gauge pressure
with outputs of 0-5V, 0-10V, 4-20mA, and can also be customized for
other outputs. The accuracy of Model 161 was ±1.0%FS, 0.4%FS or 0.25%FS
at room temperature. The temperature compensation ranges from 4 ℃ to
77℃, and the temperature effect is less than ±0.05%FS/℃.

Model
161 has excellent performance-price ratio, widely used in HVAC,
environmental pollution control, clean engineering, medical instruments
and equipment, oven pressurization and furnace pressure control, natural
gas, gas pipe network monitoring, underground ventilation and power
plant wind pressure monitoring and other fields.
