High accuracy DMP 333i pressure sensor for mineral hydraulic oil use on material testing machines with 4-20mA output.
This version of the DMP 333i pressure sensor is intended for demanding applications like material testing machines, where high accuracy and reliability are paramount. These machines, used extensively in quality control and research labs, exert precise amounts of force to test the tensile and compressive strength of materials. Accurate pressure measurement within the hydraulic system is crucial for controlling this force and ensuring the validity of the test results.
The force applied to the test specimen is directly related to the hydraulic pressure measured by the DMP 333i. To calculate the force, the pressure reading is multiplied by the effective area of the hydraulic actuator, typically the cross-sectional area of the piston. The formula is:
Force (F) = Pressure (P) x Area (A).
For example, if the DMP 333i reads 1,000 psi and the actuator has a piston with a cross-sectional area of 2 square inches, the force applied to the test specimen would be:
F = 1000 psi x 2 in² = 2000 pounds of force.
It’s important to note that this calculation assumes an ideal hydraulic system with no losses due to friction or other inefficiencies. In real-world applications, there will always be some degree of loss, and the actual force applied may be slightly lower than the calculated value. However, the high accuracy of the DMP 333i ensures that the pressure reading used in this calculation is as precise as possible, minimizing any potential errors.
This ability to accurately determine the applied force is essential for material testing machines. It allows engineers and researchers to precisely control the stress applied to the test specimen, ensuring the accuracy and reliability of the test results. This data is crucial for evaluating material properties, ensuring quality control, and validating designs.
The accuracy of the DMP 333i is crucial in this application as it directly impacts the accuracy of the calculated force and the reliability of the material test results. The sensor’s robust construction and IP67 rated housing ensure reliable operation in demanding industrial environments. The 4-20mA output signal allows for easy integration with control systems and data acquisition devices.
The sensor is installed using a 1/4 inch NPT tapered male thread to measure the mineral hydraulic oil, and the 4 to 20 milliamps current loop output is connected to signal monitoring instrumentation using the IP67 rated field housing with wire terminals and cable gland.
The DMP 333i‘s high accuracy, 16-bit analog-to-digital conversion ensures that the pressure readings used to control the hydraulic system are extremely precise, contributing to the overall accuracy and reliability of the material testing process.
