Calibration Bench Technical Description This calibration bench enables to study the function and transient response of industrial control circuit components as controllers, control valves, pressure sensors, measuring transducers, etc. (not supplied). It also contains precise sensors for standardized current signals and the corresponding pressure and current measuring units. A height adjustable water tank with level tube allows the precise setting of even very low pressures. A sturdy assembly tube is used for the proper attachment of test components. The entire unit is set up on a laboratory trolley with four castors.
