Transducer Specifications Click on the below links for the corresponding technical data sheets. Uncertainty is also defined as an estimated error, which is the difference between the true value and the measured value. There are many aspects of a pressure sensor that determine whether it is the right choice for a given application. The reason why pressure transducer frequency response is important is that in many cases, the pressure to be measured using the pressure transducer can change very rapidly. Pressure transmitters use many different sensing technol ogies and can measure the pressure of liquids and/or gases. Handheld Infrared Industrial Thermometers, Temperature Connectors, Panels and Block Assemblies, Temperature and Humidity and Dew Point Meters, Multi-Channel Programmable and Universal Input Data Loggers.

All Rights Reserved. Touch-screen Display 37. Omega’s PX309 Stainless Steel Pressure Transducer features an accurate silicon sensor protected by an oil-filled stainless-steel diaphragm. It should not be confused with accuracy which refers to how close a measured output or reading is to the actual pressure rather than how straight they all are. Zero Offset Zero output is factory set to within a certain % of full scale. Root Sum Squares (RSS): accuracy of a pressure transducer is calculated by taking the square root of non-linearity + hysteresis + non-repeatability. Hysteresis The maximum difference in output at any pressure value within the specified range, when the value is approached with increasing and decreasing pressure. SPeCIFICATIOnS OPerATIOn The uCP-242 accepts a 4-20 mA signal and outputs 3-15 psig. USB Load Cells: Do More with the Measurement Data, @media screen and (max-width:1024px){ A pressure transducer, often called a pressure transmitter, is a sensor that converts pressure into an analog electrical signal.Although there are various types of transducers, one of the most common is the strain-gage wheatstone bridge pressure transducer.

Average resolution is the median of the best and worst values. Product Finder. 17844 Pressure Transducer “Sensonor”, type SP-844, complete with one dome 17844-001 lodged in its plastic case. If you use a pressure sensor with a 1000 psi maximum range, it will not be able to read the pressure values beyond 1000 psi. This delay or lag leads to hysteresis. All these readings get updated and displayed on the monitor. If you have a setup that makes 1000 psi of pressure, then the pressure sensor you choose must have a range more than the maximum value to be measured. The models CPT6180 and CPT6100 precision pressure transducers are compact, robust sensors with a serial output and a measuring range which is freely selectable between -15... 6,000 psi (-1... 400 bar).
