Barksdale's 440 Series Intrinsically Safe Transducers provide high accuracy pressure measurement when operating in Class I, Division I environments. Intrinsically safe transducers prevent personal injury and machinery damage by preventing the explosion in the first place. External zener barriers are required in order to meet UL requirements for an intrinsically safe installation. The higher cost of having to install a zener barrier is offset with the comfort of knowing that an explosion will not occur within normal operating conditions. Three models are available: Series 443 (0-5V), Series 445 (4-20mA) and Series 446 (0-10V).
