摘要:
An electrical connector for connection to a sensor has an integrated microcontroller, with a plug-and-socket connection for connection to an interface of the sensor and with an electronic circuit. With the connector, the data of a sensor, especially the parameter data, can be mirrored outside the sensor in a simple and economical manner so that the data are available at any time and as much as possible on site. The electronic circuit has a memory for storage of data, especially parameter data and characteristic data of the sensor, and a microcontroller, the microcontroller operating the interface of the sensor, and depending on the characteristic data of the sensor, either reading data, especially parameter data, out of the sensor via the interface and storing it in the memory, or reading data stored in the memory, especially parameter data, out of the memory and transmitting them via the interface into the sensor.
摘要:
The invention relates to pressure measurement apparatuses and pressure or force measurement devices for static or dynamic pressure measurement, in particular for high pressures or forces, whose housing contains among other things, a pressure or force measuring cell, e.g. a piezoresistive or capacitive measuring cell. In devices like this, service life and chemical resistance are problematic. The pressure measurement device according to the invention is essentially comprised of a housing (2), a seal (4) between the pressure medium and the inner chamber (2d) of the housing (2), a pressure measuring cell (3), whose first main face (3e) is exposed to the pressure medium and which has a deflection when pressure loaded, which deflection leads to a relative movement between pressure measuring cell (3) and housing (2) in the region of the seal (4). In the region of the seal (4), the housing (2) is embodied so that it has spring-elastic properties. The pressure measurement apparatus according to the invention is comprised of a flange (7) with a conical sealing rib (7b) in the through opening (7f) and a pressure measurement device (9) with a housing (2) that is rotationally symmetrical in the region of the flange (7). The sealing rib (7b) is embodied as an elastic sealing rib.
摘要:
An electrical measurement device is described, with a measurement input, an integrated sensor, a measurement and evaluation circuit, and a measured value display, and several measured value outputs. The electrical measurement device enables not only one measured value or several measured values to be determined, but makes it possible to display and process the determined measured values depending on other values such as comparison values and setpoints. An influencing input acts on the measurement and evaluation circuit and is the connecting point for the electrical measurement device to which or via which an influencing value can be applied or input. Therefore, a value with which the measured value can be influenced in the broadest sense is applied.
摘要:
A measurement apparatus for determining the position of an object relative to a reference surface, with a measurement nozzle, a reference nozzle, and a measurement device, the outlet opening of the measurement nozzle being located in the reference surface. A compressed air source provides air having a certain feed pressure so that the measurement device acquires one of three state variables: flow rate, pressure and speed of the air upstream of the measurement nozzle.
摘要:
A ceramic pressure measurement cell for use in a sensor for static and/or dynamic monitoring of the pressure of a liquid or flowable medium which includes a base body and a membrane connected to the base body such that one side of the membrane is in contact with the medium to be monitored. The pressure measurement cell has high chemical resistance and high temperature resistance for a plurality of chemicals which is achieved by applying at least one plastic film on the side of the membrane in contact with the medium.
