Purpose

of ZET 7012-A-VER.1 digital pressure meter

ZET 7012-A-VER.1 digital pressure meter is used for fast and simple absolute pressure measurements and measured values data transfer in digital format via RS-485 or 4-20 mA interface.

ZET 7012-A-VER.1 digital pressure meter is intended for integration into various technological processes automated control systems.

Measuring network layout

based on ZET 7012-A-VER.1 digital pressure meter

Using digital pressure meters is especially convenient when establishing distributed measuring networks. Unlike normally used centralized measuring networks, there is no need to use “star” conection, which allows to reduce overall cable length. Since the data is transmitted in digital format, the are less requirements to data transfer channel, besides, one can use relatively inexpensive cables for the measuring network establishing.

In order to connect the measuring network to ZETLAB and ZETVIEW systems, one can use interface converter ZET 7070 (USB ↔ RS-485) or ZET 7076 (Ethernet ↔ RS-485). Using inner power supply module ZET 7070 one can connect up to 4 digital sensors to a single ZET 7070 module (and up to 60 digital sensors if external power supply module is used).

ZETLAB Software enables connection of up to 1024 sensors to a single PC. Measuring networks can also be connected to any system using Modbus protocol via RS-485 interface.
