VERNIER气压传感器介绍

The Vernier Gas Pressure Sensor is used to monitor pressure changes in gas-law experiments in chemistry, biology, and physics.

What's Included

two tapered valve connectors

one tapered valve connector inserted into a No. 1 stopper

one two-way valve

two Luer-lock connectors connected to either end of a piece of plastic tubing

one 20 mL syringe

two transpiration tubing clamps

How the Sensor Works

The sensor in this unit has a membrane that flexes as pressure changes. This sensor is arranged to measure absolute pressure. One side of the membrane is a vacuum, while the other side is open to the atmosphere. The sensor produces an output voltage that varies in a linear way with absolute pressure. It includes special circuitry to minimize errors caused by changes in temperature.

传感器的工作原理

该装置中的传感器有一个薄膜，可随着压力变化而弯曲。该传感器被布置用于测量绝对压力。膜的一侧是真空，而另一侧对大气开放。传感器产生的输出电压随绝对压力呈线性变化。它包括特殊电路，可最大限度地减少温度变化引起的错误。
