Product Details:
SMT-H1 field type weighing instrument is a tank weighing manager developed for industrial weighing field applications. It can be widely used for weighing tanks and silos in concrete and asphalt mixing stations, feed, metallurgy, chemical batching and other applications.
Product parameters:
1,Suspended field installation method, dustproof, IP65 waterproof shell; |
2, 1-way 6-wire analog sensor scale interface, connect up to 8 350Ω sensors; |
3, support for theoretical value calibration and weight calibration two ways; |
4,Support 1 RS485 serial port communication function and 1 network port communication function; |
5,Support GPRS, Modbus-RTU (serial port), Modbus-TCP/IP (network port) communication and continuous reporting, can be automatically uploaded at set intervals of instrument status and weight information, in and out of the material information; |
6, through the GPRS or 4G way, remote wireless transmission of weight, material level heartbeat packet data and in and out of the material time, weight records and other data; |
7,Input scanning through IO port to get material level information. |
