Product Overview

The PC420A-IS series intrinsically safe 4-20 mA loop-powered sensors are designed for reliable operation in hazardous environments. These sensors offer true RMS or peak output and are easily integrated into existing process control systems. Manufactured in an ISO 9001 approved facility, they are certified intrinsically safe for use in Class I, Div 1 Groups A, B, C, D T3C and II 1 G Ex ia IIC T4 Ga hazardous locations. They are suitable for applications requiring accurate vibration monitoring in potentially explosive atmospheres.
