Membrane pressure sensor ZET 7112-I VER.2

digital

Integrated primary transducer Open membrane Ready for operation CAN 2.0 interface ZET 7112-I VER.2 digital gauge pressure (open membrane) is used for fast and simple pressure measurements and measured values data transfer in digital format via CAN 2.0 interface. ZET 7112-I VER.2 digital gauge pressure (open membrane) is intended for integration into various technological processes automated control systems. Open membrane type enables pressure meters operation in viscous, pasty and rapidly polymerizing environments. ZET 7112-I VER.2 digital gauge pressure (open membrane) consists of primary transducer and measuring module integrated into a single package. This allows to perform digital signal processing in direct vicinity to the transducer signal, which positvely affects the measurement results. 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. Primary transducer performs pressure value conversion to analog signal. Then the measuring module performs digital processing of the signal by means of 24-digit ADC and transfers the digital pressure value via CAN 2.0 interface. The measuring module also has self-diagnostics, automated calibration and data quality control functions.
