German Kracht Indicator

The German Kracht indicator is a device used to measure and monitor the pressure, temperature, and flow rate of fluid systems. It typically includes a pointer or digital display screen that displays the measured value and has the ability to adapt to different units and measurement ranges. These indicators are widely used in the industrial field for controlling and monitoring parameters of hydraulic systems, lubrication systems, and other fluid transmission systems.

The German Kracht indicator is mainly used to measure and monitor parameters in hydraulic and mechanical transmission systems, such as pressure, flow rate, temperature, and speed. These indicators use high-precision sensors and measurement technology to provide accurate and reliable measurement results. And it has a user-friendly design and operating interface, usually with a digital display screen and functional buttons, allowing users to easily read and adjust measurement parameters.

The German Kracht indicator is widely used in various industries, including mechanical manufacturing, automotive engineering, aerospace, energy, and chemical engineering. Its high precision and reliability make it an important tool for engineers and technicians to conduct system monitoring and fault diagnosis.

　　1German Kracht IndicatorThe functional applications are as follows:

The plug-in display SD1 is a versatile on-site display that can be used for all flow meter product lines produced by KRACHT with (compliant with DIN 43650 standard) connector interfaces.

The monitor only needs to be directly plugged into the middle of the flowmeter connector and socket. You can choose to display the flow rate or volume on the display screen. Like standard measuring instruments, it can output square wave signals for external reprocessing. Previously purchased flow meters can be additionally equipped with this plug-in display. SD1-I-24 requires the removal of the amplifier circuit board from the existing flowmeter connector for this purpose. The plug-in display of SD1-I-24 can be programmed freely. All necessary settings can be completed with just two buttons. Program data is stored in EEPROM, so it will not be lost even in the event of a power outage.
