Description

AST 3P is a DIN rail mounted, high performance weight transmitter designed for apllications with strain gauge transducers. It converts the output from connected load cells into a very stable signal suitable for PC or PLC based control systems.

AST 3P weight meter is typically used where a local display is essential either for displaying data or for front panel set-up. The set-up and calibration procedure is easily performed either from the front panel or by using the deltaCOM programme via a standard PC running under Windows 95/98/2000/NT4/ME/XP/Windows 7/Windows 8/ Windows 10. All set-up data can be stored in the host computer and downloaded in case of replacement of the transmitter with PC software deltaCOM.

The transmitter is fitted with two relay outputs having a response time of less than 20 ms. for use in high precision level control applications. A unique and patented A/D converter, of high resolution and stability, serves as the heart of the transmitter. This advanced technology provides both analogue and CONFIGURATION serial outputs which can be conditioned to give the user accurate, stable and rapid response measurement information.

The AST 3P is compatible with other instruments in the BLH Nobel program and can communicate via standard RS-485/MODBUS RTU protocol with a common process control host – PC/PLC. Fieldbus communication is possible via the GATE 3S module from BLH Nobel. The transmitter is CE marked, and fully compliant with the EMC and Low Voltage directives.
