[APPLICATION]: Normal Ambient Temperature: -4°F to +140°F (-20°C to +60°C). It is suitable for environments with severe vibration; the damping liquid (glycerin) can withstand the vibrations of the working environment and reduce the pulsating effects of medium pressure.
Dial Size: 2" Dial Size (Crimped Casing) Accuracy: +/- 3/2/3% Scale: Dual Scale - PSI / Bar Movement: Copper Alloy Bourdon Tube: Copper Alloy Window: Polycarbonate Case: Stainless Steel case for protection in harsh environments Connection: Copper Alloy Lower Mount; 1/4" NPT (for 2" dial) Normal Ambient Temp.: -4F to +140F (-20C to +60C) Liquid Filling: Glycerin oil filled to enhance the reliability and integrity; helps dampen the effect of vibration and pulsation; lubricates the movement and extends the life of gauge.
