Defining Differential Pressure Transmitters
Differential pressure transmitters, such as the WIKA DPT-20, are designed to measure the difference in pressure between two points in a system. These instruments translate pressure variations into standardized electrical signals, which can then be interpreted by control systems. They are essential in a variety of applications ranging from water treatment plants to oil and gas extraction sites.
The Influence of Ambient Temperature on Accuracy
Ambient temperature can have a profound effect on the accuracy of differential pressure transmitters. Generally, these instruments are calibrated for specific temperature ranges, and deviations from this range can lead to measurement inaccuracies. As the temperature fluctuates, components within the transmitter can expand and contract, affecting the pressure readings.
