20 to 100 kPa， 0.2 to 1.0 kgf/cm2或bar，或3 to 15psi

The Model MC43 Pneumatic Indicating Controller,designed for field mounting, satisfies industry’s need for an economical, dependable means of automatically controlling on-line variables where no permanent record is required. Highly reliable, it measures and controls important process variables such as tempera-ture, pressure and liquid level. A variety of measuring elements for specific process variables can be built into its housing along with the control mechanism,making the Model MC43 a low cost, compact, stand-alone instrument which can both indicate process
variables and control them at desired setpoints. The controller’s case is weatherproof and dustproof offering excellent durability, and the indicating pointer and the setting index are visible even from a distance. Thus the MC43 is highly suitable for mounting outdoors or in the field.
