Differential pressure sensor/transmitter
Pressure medium: air or other non-conductive gas
Accuracy: ±1.0%,±0.4%,±0.25%
Range: unidirectional: 25 Pa to 25000 Pa/bidirectional: ±10 Pa to ±10000 Pa
Signal output: 4-20mA, 0-5Vdc, 0-10Vdc

The core component of the Model 167
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 167 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 167 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
167 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.
