Inductive digimatic measuring instrument uses precision circuit design principle. Sizes of workpieces can be calculated through the measured signal changes of inductive displacement sensors. Nominal value or tolerance value is displayed on the screen. Various parameters can be set in accordance with the requirements; measured values are stored in a built-in large capacity SD storage card; external RS485 and RS232 interfaces, convenient for data upload; external USB2.0 interface, exporting the saved data to the USB disk; external input and output I / O for external device control.
Digimatic pneumoelectric measuring instrument uses US precision differential pressure sensor. Sizes of workpieces can be calculated through the measured air pressure change value. Nominal value or tolerance value is displayed on the screen. With key panel, various parameters can be set in accordance with the requirements; measured values are stored in a built-in large capacity SD storage card; external RS485 and RS232 interfaces, convenient for data uploading; external USB2.0 interface, exporting the saved data to the USB disk; external input and output I / O are used for external device control.
A / E single-channel measuring instrument is used for detecting industrial high-precision air pressure changes, transforming the change amount into digital number, and transfer it to the host computer through communication interface.
Digital path box uses mixed analog and digital integrated circuit, to send a sine wave excitation signal to the LVDT displacement sensor, and process and calibrate the signals of sensors. Upload the data to the host computer through RS485 network and Ethernet.
Gateway gathers all the real-time data collected by the sensors, and uploads the data to the remote server. Gateway coordinates the data communication throughout the network.
Communication between gateway and server adopts TCP protocol. As a network connection terminal, gateway sends a connection request. If the gateway and remote server are not connected, connection requests will be sent every period of time, till they are connected. Gateway can be connected to 433 wireless communication, TCP cable network, 4G network and WIFI at the same time.
FRD-RF-1000 wireless transmission module works in the ISM 433MHz frequency band. Use GFSK modulation for front-end data processing and receiving and back-end RF data transmission.
