4 - 20毫安 数字 螺纹

集成初级传感器防爆版本RS-485数字输出4- 20ma输出版本可用数字表压力ZET 7012-I-VER。1通过RS-485或4- 20ma接口用于快速简单的超压测量和测量值数据的数字格式传输。7012 - i - ver.1 ZET数字gauge pressure is intended for integration into various technological processes automated control systems: petroleum industry; metal industry; construction industry; chemical industry; food processing industry; municipal infrastructure; automobile transportation and shipping facilities. Digital gauge pressure ZET 7012-I-VER.1 consists of primary transducer and integrated measuring module. The primary transducer converts the pressure value to analog signal. The measuring unit digitizes the signal from the converter and transmits the pressure value in a digital form via RS-485 interface by means of Modbus protocol or via data transfer interface “Current loop” (4-20 mA). The membrane of the primary transducer is made of a silicon plate. The strain resistor circuit (bridge connection) is implemented on the basis of the “silicon on sapphire” technology (SOS). This allows to perform inertia-free dynamic measurements up to 1,000 Hz. In contrast to metal membranes with glued bridge strain resistors, SOS membranes allow to register pressure change at the level of 0.00001 from the upper scale of the range. Sensitivity of the electronic amplifier is 15 nV reduced to the input. The pressure meters are attached to the measured object while the interface modules enabling data transfer are placed inside of electrical cabinets.
