Overview
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.
