It boasts an accuracy of ±0.1%FS, repetition deviation of ±0.002% FS, and repeatability of ±0.002%FS. With rapid response time of ≤ 40ms and measurement cycle of ≤100ms, the device is capable of meeting high output requirements of most real-time applications.

The operating principle behind 0936012315 is based on the piezoresistive pressure sensor. This type of sensor contains a Wheatstone bridge circuit that is composed of a Wheatstone bridge strain gauges made of four strain-sensitive resistors. When pressure is applied to the bridge, the distance between diagonals is compressed or stretched, which changes the bridge’s electrical resistance. Since the resistance of each strain gauge is proportional to the force applied to it, the output of the Wheatstone bridge is proportional to the applied pressure.

The Wheatstone bridge is connected to a suitable amplifier and bridge excitation circuit. A regulated DC supply voltage is connected to the bridge circuit to generate a stable bridge output voltage. The excitation voltage used is usually between 2.2V and 3V. The output of the amplifier is a voltage which is linearly proportional to the applied pressure. It is typically between 0V-10V. The output voltage of the amplifier is then digitized using an Analog-to-Digital Converter (ADC) to get the data ready for processing.

An advanced analog ASIC processes the measured data and calibrates it using coefficients stored in micro-controller memory. Finally, the data is used to determine the pressure level in the desired unit of measurement. The device supports two different download protocols for flexibility in system setup and operation. These two software protocols are the MODBUS protocol and HART protocol.

In summary, 0936012315 is a digital pressure transmitter suitable for a wide range of applications. It offers excellent accuracy, repeatability, resolution and linearity ensured by advanced kinds of pressure sensors, ASICs, and micro-controller processing techniques. Its wide temperature range, fast response time and two communication protocols make it an ideal choice for industrial automation, process engineering, HVAC, medical device, and pump control applications.
