YJJ SM9541-140C-S-C-3-S Pressure Sensors Are Used in Medical Dialysis Equipment

Features:

Detection of respiratory parameters of anesthesia machine is only limited to the conventional mechanical ventilation mode, and the selection of pressure sensor, a key component of anesthesia machine, is very important.

For anaesthesia machines, the pressure sensing part needs to be very sensitive in order to accurately measure the patient's inhalation and exhalation as well as the anesthetic gas delivered to the airflow.Therefore, sensors that can detect differential pressure or airflow at very low rates should be selected.The sensor should be able to measure the peak of a patient's breathing, or the turning point between inhaling and exhaling.Once pressure, airflow and media requirements are determined, precision and stability requirements, including total error bands, should be considered.Consider the design factor of getting smaller, beautiful and portable.Customer calibration may also be considered, especially for CPAP(continuous positive airway pressure) applications, to maximize product performance to match the patient's breathing pattern.

In the anesthesia machine, SM9541 pressure sensor can be used to measure expiratory velocity, inspiratory velocity, expiratory pressure, inspiratory pressure, PEEP.SM9541 series is a high stable piezoresistive pressure sensor chip mounted on a ceramic substrate. It USES the thin film resistor on the ceramic substrate for zero correction, zero temperature compensation and sensitivity temperature compensation. It is driven by a constant voltage source.

SM9541 series is a high stable piezoresistive pressure sensor chip mounted on a ceramic substrate. It USES the thin film resistor on the ceramic substrate for zero correction, zero temperature compensation and sensitivity temperature compensation. It is driven by a constant voltage source.SM9541 supports I2C data reading and can set the baud rate of 4Mhz.

1) micro pressure range: 250pxH2O, 500pxH2O, 1000pxH2O, 2500pxH2O

2) wide temperature compensation range: -5℃ to 65℃

3) accuracy: ±1%

4) zero point calibration and temperature compensation

5) high performance and stable silicon chip package

6) table pressure and differential pressure are supported

7) I2C pressure output value: 1638 to 14745

The interface of the SM9541 pressure sensor is I2C and only two 4.7k ohms are needed.A 0.1uf filter capacitor is required at the power pin.
