Range spring calibration clamp fixes live length of spring for proper gage calibration and is factory set and sealed. Silicone rubber diaphragm allows accurate response to a broad range of temperatures and at extremely low pressure. Incorporates blow out area for overpressure protection. Diaphragm support plates of lightweight aluminum on each side of the diaphragm minimize position or attitude sensitivity and help define pressure area. Flat leaf range spring reacts to pressure on the diaphragm.
Live length is adjustable for calibration.
Small amplitude of motion minimizes inaccuracies and assures long life. Low pressure tap connects to rear chamber. If necessary, surface mounting of the gage can be accomplished by means of two 4-40 screws into the tapped mounting bracket stud holes in the rear of the gage. Surface mounting requires clearance holes in the panel for the two pressure taps. 2.00 5.00 Model Number Range, PSI Minor Div.
