PS40-102V-PWM

Pressure sensors are transducers that measure and monitor the pressure within a system or environment. The PS40-102V-PWM is one such sensor whose application field and working principle we will be discussing here.

The PS40-102V-PWM is a linear pressure transducer that can measure both positive and negative pressure. This makes it ideal for applications such as differential pressure monitoring, HVACR systems, medical systems and process control applications. It has a pressure range of -102 to +122 kPa, and an output range of 4-20 mA. It is also compatible with most common electrical systems.

The working principle of the PS40-102V-PWM involves an internal Wheatstone bridge circuit that converts the measured pressure into a linear output. This bridge is constructed with four strain gauges arranged in a Wheatstone bridge configuration. When pressure is applied to the sensor, the strain gauges are displaced and the resistance value of the bridge changes accordingly. This change in resistance is then converted into a linear output using a precision operational amplifier.

The PS40-102V-PWM also includes a pulse width modulation (PWM) output. This PWM output is used to provide an analog to digital conversion of the linear output signal. The PWM signal is created by sampling the linear output signal and then converting it into a proportional duty cycle signal. This allows the PS40-102V-PWM to be accurately interfaced with digital systems such as microprocessors and other digital control systems.

The PS40-102V-PWM is a reliable and accurate pressure transducer that has a wide range of applications. It can be used to measure and monitor pressure in industrial, medical and process control applications. The PWM output makes it easy to interface with digital systems, allowing for accurate and robust data collection and analysis.
