The core component of the Model 162
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 162 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 162 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
162 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.
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
