D&D Valve & Engineering Supplies offers a range of pressure gauges and thermometers suitable for various applications.
When purchasing a pressure gauge, accuracy is the main consideration. To ensure a pressure gauge has the accuracy required by your application, you need to understand how accuracy is graded by gauge manufacturers.
There are two sets of standards that define the accuracy grades of pressure gauges: ASME B40.1 defines the accuracy grades of dial-type gauges while ASME B40.7 defines the accuracy grades of digital gauges.
The accuracy of pressure gauges is determined under extremely specific environmental conditions, such as a temperature of 23°C and barometric pressure of 29.92 in Hg. Conditions other than these can affect gauge accuracy.
Dial thermometers work on the bimetal, expansion or gas actuation principle and are suited to operation in a thermowell. Various connection designs, stem diameters and individual stem lengths enable a flexible measuring point design.
V-shaped straight, and angle, pipe thermometers are suitable for use in many industrial and heating facilities, where robustness, reliability and resistance to vibration are necessary.
