Pressure sensors and transducers are becoming increasingly common in the consumer and industrial markets, due to the need to measure and control pressure accurately. The 26PCAFA2G pressure sensor and transducer are specifically designed for applications where a high accuracy and degree of repeatability are required.

The 26PCAFA2G pressure sensor is a combined pressure transducer and transmitter that provides a high precision, single point, absolute pressure measurement. It uses a micro-machined diaphragm with a silicon strain gauge that provides a low-hysteresis, repeatable output signal with a high degree of accuracy (+/- 0.2% FSO).

The 26PCAFA2G pressure sensor is designed to operate with a range of pressure inputs, from vacuum to positive pressures up to 6 bar (or equivalent). This pressure range is communicated to the user via a 0-5 VDC or 4-20 mA analog signal. It also features a second temperature sensing element which can be used to measure the change in output voltage that occurs with changes in ambient temperature. The internal electronic circuit compensates the signal for changes in temperature, thus improving accuracy.

The 26PCAFA2G is designed for use in a variety of pressure sensing and control applications, ranging from medical equipment such as ventilators and anaesthetizers, to HVAC systems and process control equipment. It is rugged enough to withstand harsh environments, including extreme temperatures up to 125°C and is hermetically sealed for increased protection and durability.

The 26PCAFA2G is easy to install and use, with simple connections to the pressure source and a single connection to an external sensor. It contains an embedded microcontroller, allowing for simple programming and configuration of parameters. It also has integrated protection features that protect the sensor from overload, reverse output, and short circuit.

The working principle of the 26PCAFA2G pressure sensor is based on the elastomeric diaphragm principle. Pressure is applied to the diaphragm, which creates a strain in the elastic material. This strain is transferred into an electrical signal via a strain gauge. The strain gauge is attached to a Wheatstone Bridge circuit, which amplifies the signal and sends it to the output. The output signal is a function of the input pressure and can be calibrated to gain a desired reading.

The 26PCAFA2G pressure sensor is a reliable and accurate pressure measuring device, designed for use in a variety of applications where accuracy is essential. Its high degree of accuracy, low hysteresis, and robust design make it an ideal choice for a variety of pressure sensing and control applications.
