Data refresh rate 1, 5, 25, 100, 200 Hz Synchronization accuracy ±1 µsec Data transmission interface CAN 2.0 The ZET 7112-A VER.2 pressure meter is intended for use in automated process control systems for various industrial applications: petroleum and natural gas industry; metallurgy industry; energy industry; construction industry; chemical industry; food industry; utilities and water supply; motorized and shipping facilities; It is a digital pressure meter for simple and fast pressure measurements which transmits the measured values in a digital form via CAN 2.0 interface. Functional units of ZET 7112-A VER2 pressure meter are as follows: a primary transducer and a measuring unit; they are combined in a single cover which ensures digital processing of the signal from the transducer within the minimum distance from it, which significantly decreases distortions of the measurement result. The primary transducer converts the pressure to analog signal. The measuring unit digitizes the signal from the converter and transmits the pressure value in a digital form via CAN 2.0 interface. 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 glue-fixed bridge strain resistors, SOS membranes allow to register pressure change at the level of 0.00001 of the upper scale of the range. Sensibility of the electronic amplifier is 15 nV reduced to the input.
