Palmer Wahl: Digital Pressure Gauges
January 23, 2012
Digital pressure gauges have been added to the line of process pressure instrumentation. With a 2.5-inch dial face, EDG gauges display both positive and negative pressures on an easy-to-read LCD screen. Accuracy of ±1 percent of full scale provides the reliability needed for the user’s process. Settable resolutions of 0.1, 0.2, 0.5, and 1 whole unit allow flexibility in readings. User-selectable single-point calibration with known pressure input allows the user to minimize errors at the user’s expected operation pressure, for optimum accuracy. Standard 9-V battery is good for approximately 1,500 hours (8,000 cycles) and is easy to replace. The auto-off timer feature saves battery life, allowing the gauge to be always on, or to auto shut off in increments between 30 seconds and 180 seconds. The gauge allows the unit of measurement to be selected: pounds per square inch (psi), bar, kilogram-force per square centimeter, or kilopascals for standard ranges; millibar, millimeters of mercury, and inches of mercury for compound ranges. Models include bottom ¼-inch NPT connection for versatile installation options and protective rubber boot for impact dampening. For corrosive liquid applications, 316SS internals are available. Compound and standard ranges are available.
