Pressure sensor

The Pressure sensor BT66i is designed to measure absolute gas pressure. It has two measurement ranges, which can be selected using a switch located on the side of the sensor box, 0 .. 700 kPa range and 0 .. 130 kPa range.
The pressure is measured via a pressure port located next to the switch. The pressure port has a small threaded end called a Luer-lock. With a gentle half turn, you may attach a plastic tube or a valve with Luer-lock connectors. You can also attach the 20-ml plastic syringe included with the sensor directly to this port.
The BT66i Pressure sensor is delivered with the following accessories:
- one plastic 20-ml syringe with Luer-lock,
- two plastic tubes (5 cm and 45 cm long),
- one three-way valve with Luer- lock connectors, and
- two Luer-lock connectors.
The Pressure sensor can be used in various experiments such as:
• Measurements of pressure changes in gas-law experiments, Boyle's and Gay-Lussac's laws,
• Measurements of vapor pressure of liquids,
• Measurements of reaction rates as a gas is produced in chemical reactions.
If the sensor pressure port is left open to the atmosphere, the Pressure Sensor will display the value for atmospheric (barometric) pressure. The measurement range 0 .. 130 kPa is suitable to measure such air pressure for weather studies or to perform measurements of the air pressure over a longer period of time or at different altitudes.

The Pressure sensor BT66i can be directly connected to the analog BT inputs of the CMA interfaces. Attention: The sensor cable BT - IEEE1394 needed to connect the sensor to an interface is not supplied with the sensor and has to be purchased separately (CMA Art. Nr BTsc_1).

Technical specifications of the sensor are descibed in its User's guide.
